cause significant low back pain and radicular pain that could profoundly impair daily life activities of individuals. Patients who undergo surgical treatment for lumbar disc herniation usually present with radiculopathy along with low back pain (LBP) instead of radiculopathy alone. When discectomy is performed, improvement in leg radiating pain is observed due to spinal nerve irritation. However, long-term LBP due to degenerative changes in the disc may occur postoperatively. In addition, limited research has been reported on the short-term (within 1 year) improvement in LBP after discectomy. In this study we would like to share our minimally invasive open technique for lumbar discectomy with annuloplasty and nuceloplasty as a technique for effective reduction of both axial and radicular pain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nucleoplasty" title="nucleoplasty">nucleoplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=sinuvertebral%20nerve%20cauterization" title=" sinuvertebral nerve cauterization"> sinuvertebral nerve cauterization</a>, <a href="https://publications.waset.org/abstracts/search?q=annuloplasty" title=" annuloplasty"> annuloplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=discogenic%20low%20back%20pain" title=" discogenic low back pain"> discogenic low back pain</a>, <a href="https://publications.waset.org/abstracts/search?q=axial%20pain" title=" axial pain"> axial pain</a>, <a href="https://publications.waset.org/abstracts/search?q=radicular%20pain" title=" radicular pain"> radicular pain</a>, <a href="https://publications.waset.org/abstracts/search?q=minimally%20invasive%20lumbar%20discectomy" title=" minimally invasive lumbar discectomy"> minimally invasive lumbar discectomy</a> </p> <a href="https://publications.waset.org/abstracts/168826/minimally-invasive-open-lumbar-discectomy-with-nucleoplasty-and-annuloplasty-as-a-technique-for-effective-reduction-of-both-axial-and-radicular-pain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168826.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">68</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">827</span> The Effect of Intrathecal Adenosine in Control of Neuropathic Pain after Lumbar Discectomy in One Level</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dawood%20Aghamohammadi">Dawood Aghamohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Eidi"> Mahmoud Eidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Pishgahi"> Alireza Pishgahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Azam%20Esmaeilnejad"> Azam Esmaeilnejad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Adenosine has an analgesic and anti-inflammatory role and its injections are used for peri-operative pain management. We want to study efficacy of intrathecal injection of adenosine for post operative radicular pain after lumbar discectomy. 40 patients with unilevel lumbar discectomy who had radicular lower limb pain were treated by 1000 micrograms of intrathecal injection of adenosine. Pain severity, pain killer consumption per day and sleep quality were assessed during a 3 months follow up period. Radicular pain severity was significantly reduced in 3 month follow-up period in comparison to the baseline (F=19760, DF=2.53, p-value<0.001). Further painkiller medication consumption rate in average during 3 month follow-up period after injection was significantly lower in comparison to baseline (F= 19.244, df= 1.98, p-value<0.001). This study suggests that intrathecal injection of adenosine is a safe method in order to reduce postoperative pain after lumbar discectomy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adenosine" title="adenosine">adenosine</a>, <a href="https://publications.waset.org/abstracts/search?q=intrathecal%20injection" title=" intrathecal injection"> intrathecal injection</a>, <a href="https://publications.waset.org/abstracts/search?q=discectomy" title=" discectomy"> discectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=neuropathic%20pain" title=" neuropathic pain"> neuropathic pain</a> </p> <a href="https://publications.waset.org/abstracts/74844/the-effect-of-intrathecal-adenosine-in-control-of-neuropathic-pain-after-lumbar-discectomy-in-one-level" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74844.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">252</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">826</span> Finite Element Analysis of the Lumbar Spine after Unilateral and Bilateral Laminotomies and Laminectomy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chih-Hsien%20Chen">Chih-Hsien Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Hung%20Ho"> Yi-Hung Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih-Wei%20Wang"> Chih-Wei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih-Wei%20%20Chang"> Chih-Wei Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yen-Nien%20Chen"> Yen-Nien Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih-Han%20Chang"> Chih-Han Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-Ting%20Li"> Chun-Ting Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Laminotomy is a spinal decompression surgery compatible with a minimally invasive approach. However, the unilateral laminotomy for bilateral side decompression leads to more perioperative complications than the bilateral laminotomy. Although the unilateral laminotomy removes the least bone tissue among the spinal decompression surgeries, the difference of spinal stability between unilateral and bilateral laminotomy and laminectomy is rarely investigated. This study aims to compare the biomechanical effects of unilateral and bilateral laminotomy and laminectomy on the lumbar spine by finite element (FE) simulation. A three-dimensional FE model of the lumbar spine (L1–L5) was constructed with the vertebral body, discs, and ligaments, as well as the sacrum was constructed. Three different surgical methods, namely unilateral laminotomy, bilateral laminotomy and laminectomy, at L3–L4 and L4–L5 were considered. Partial pedicle and entire ligamentum flavum were removed to simulate bilateral decompression in laminotomy. The entire lamina and spinal processes from the lower L3 to upper L5 were detached in the laminectomy model. Then, four kinds of loadings, namely flexion, extension, lateral bending and rotation, were applied on the lumbar with various decompression conditions. The results indicated that the bilateral and unilateral laminotomy both increased the range of motion (ROM) compared with intact lumbar, while the laminectomy increased more ROM than both laminotomy did. The difference of ROM between the bilateral and unilateral laminotomy was very minor. Furthermore, bilateral laminotomy demonstrated similar poster element stress with unilateral laminotomy. Unilateral and bilateral laminotomy are equally suggested to bilateral decompression of lumbar spine with minimally invasive technique because limited effect was aroused due to more bone remove in the bilateral laminotomy on the lumbar stability. Furthermore, laminectomy is the last option for lumbar decompression. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=minimally%20invasive%20technique" title="minimally invasive technique">minimally invasive technique</a>, <a href="https://publications.waset.org/abstracts/search?q=lumbar%20decompression" title=" lumbar decompression"> lumbar decompression</a>, <a href="https://publications.waset.org/abstracts/search?q=laminotomy" title=" laminotomy"> laminotomy</a>, <a href="https://publications.waset.org/abstracts/search?q=laminectomy" title=" laminectomy"> laminectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a> </p> <a href="https://publications.waset.org/abstracts/106868/finite-element-analysis-of-the-lumbar-spine-after-unilateral-and-bilateral-laminotomies-and-laminectomy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106868.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">186</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">825</span> Comparative Study on Efficacy and Clinical Outcomes in Minimally Invasive Surgery Transforaminal Interbody Fusion vs Minimally Invasive Surgery Lateral Interbody Fusion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sundaresan%20Soundararajan">Sundaresan Soundararajan</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Ezekiel%20Silvananthan"> George Ezekiel Silvananthan</a>, <a href="https://publications.waset.org/abstracts/search?q=Chor%20Ngee%20Tan"> Chor Ngee Tan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Transforaminal Interbody Fusion (TLIF) has been adopted for many decades now, however, XLIF, still in relative infancy, has grown to be accepted as a new Minimally Invasive Surgery (MIS) option. There is a paucity of reports directly comparing lateral approach surgery to other MIS options such as TLIF in the treatment of lumbar degenerative disc diseases. Aims/Objectives: The objective of this study was to compare the efficacy and clinical outcomes between Minimally Invasive Transforaminal Interbody Fusion (TLIF) and Minimally Invasive Lateral Interbody Fusion (XLIF) in the treatment of patients with degenerative disc disease of the lumbar spine. Methods: A single center, retrospective cohort study involving a total of 38 patients undergoing surgical intervention between 2010 and 2013 for degenerative disc disease of lumbar spine at single L4/L5 level. 18 patients were treated with MIS TLIF, and 20 patients were treated with XLIF. Results: The XLIF group showed shorter duration of surgery compared to the TLIF group (176 mins vs. 208.3 mins, P = 0.03). Length of hospital stay was also significantly shorter in XLIF group (5.9 days vs. 9 days, p = 0.03). Intraoperative blood loss was favouring XLIF as 85% patients had blood loss less than 100cc compared to 58% in the TLIF group (P = 0.03). Radiologically, disc height was significantly improved post operatively in the XLIF group compared to the TLIF group (0.56mm vs. 0.39mm, P = 0.01). Foraminal height increment was also higher in the XLIF group (0.58mm vs. 0.45mm , P = 0.06). Clinically, back pain and leg pain improved in 85% of patients in the XLIF group and 78% in the TLIF group. Post op hip flexion weakness was more common in the XLIF group (40%) than in the TLIF group (0%). However, this weakness resolved within 6 months post operatively. There was one case of dural tear and surgical site infection in the TLIF group respectively and none in the XLIF group. Visual Analog Scale (VAS) score 6 months post operatively showed comparable reduction in both groups. TLIF group had Owsterty Disability Index (ODI) improvement on 67% while XLIF group showed improvement of 70% of its patients. Conclusions: Lateral approach surgery shows comparable clinical outcomes in resolution of back pain and radiculopathy to conventional MIS techniques such as TLIF. With significantly shorter duration of surgical time, minimal blood loss and shorter hospital stay, XLIF seems to be a reasonable MIS option compared to other MIS techniques in treating degenerative lumbar disc diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extreme%20lateral%20interbody%20fusion" title="extreme lateral interbody fusion">extreme lateral interbody fusion</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20approach" title=" lateral approach"> lateral approach</a>, <a href="https://publications.waset.org/abstracts/search?q=minimally%20invasive" title=" minimally invasive"> minimally invasive</a>, <a href="https://publications.waset.org/abstracts/search?q=XLIF" title=" XLIF"> XLIF</a> </p> <a href="https://publications.waset.org/abstracts/75842/comparative-study-on-efficacy-and-clinical-outcomes-in-minimally-invasive-surgery-transforaminal-interbody-fusion-vs-minimally-invasive-surgery-lateral-interbody-fusion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75842.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">220</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">824</span> Effect of Rehabilitative Nursing Program on Pain Intensity and Functional Status among Patients with Discectomy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amal%20Shehata">Amal Shehata</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Low back pain related to disc prolapse is localized in the lumbar area and it may be radiated to the lower extremities, starting from neurons near or around the spinal canal. Most of the population may be affected with disc prolapse within their lifetime and leads to lost productivity, disability and loss of function. The study purpose was to examine the effect of rehabilitative nursing program on pain intensity and functional status among patients with discectomy. Design: Aquasi experimental design was utilized. Setting: The study was carried out at neurosurgery department and out patient's clinic of Menoufia University and Teaching hospitals at Menoufia governorate, Egypt. Instrument of the study: Five Instruments were used for data collection: Structured interviewing questionnaire, Functional assessment instrument, Observational check list, Numeric rating Scale and Oswestry low back pain disability questionnaire. Results: There was an improvement in mean total knowledge score about disease process, discectomy and rehabilitation program in study group (25.32%) than control group (7.32%). There was highly statistically significant improvement in lumbar flexibility among study group (80%) than control group (30%) after rehabilitation program than before. Also there was a decrease in pain score in study group (58% no pain) than control group (28% no pain) after rehabilitation program. There was an improvement in total disability score of study group (zero %) regarding effect of pain on the activity of daily living after rehabilitation program than control group (16%). Conclusion: Application of rehabilitative nursing program for patient with discectomy had proven a positive effect in relation to knowledge score, pain reduction, activity of daily living and functional abilities. Recommendation: A continuous rehabilitative nursing program should be carried out for all patients immediately after discectomy surgery on regular basis. Also A colored illustrated booklet about rehabilitation program should be available and distributed for all patients before surgery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discectomy" title="discectomy">discectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitative%20nursing%20program" title=" rehabilitative nursing program"> rehabilitative nursing program</a>, <a href="https://publications.waset.org/abstracts/search?q=pain%20intensity" title=" pain intensity"> pain intensity</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20status" title=" functional status"> functional status</a> </p> <a href="https://publications.waset.org/abstracts/124192/effect-of-rehabilitative-nursing-program-on-pain-intensity-and-functional-status-among-patients-with-discectomy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124192.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">823</span> Minimally Invasive versus Conventional Sternotomy for Aortic Valve Replacement: A Systematic Review and Meta-Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Shaboub">Ahmed Shaboub</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Jasim%20Althawadi"> Yusuf Jasim Althawadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shadi%20Alaa%20Abdelaal"> Shadi Alaa Abdelaal</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hussein%20Abdalla"> Mohamed Hussein Abdalla</a>, <a href="https://publications.waset.org/abstracts/search?q=Hatem%20Amr%20Elzahaby"> Hatem Amr Elzahaby</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Mohamed"> Mohamed Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Hazem%20S.%20Ghaith"> Hazem S.

Methods: We conducted a PRISMA-compliant systematic review and meta-analysis. We ran an electronic search of PubMed, Cochrane CENTRAL, Scopus, and Web of Science to identify the relevant published studies. Data were extracted and pooled as standardized mean difference (SMD) or risk ratio (RR) using StataMP version 17 for macOS. Results: Forty-one studies with a total of 15,065 patients were included in this meta-analysis (minimally invasive approaches n=7231 vs. conventional sternotomy n=7834). The pooled effect size showed that minimally invasive approaches had lower mortality rate (RR 0.76, 95%CI [0.59 to 0.99]), intensive care unit and hospital stays (SMD -0.16 and -0.31, respectively), ventilation time (SMD -0.26, 95%CI [-0.38 to -0.15]), 24-h chest tube drainage (SMD -1.03, 95%CI [-1.53 to -0.53]), RBCs transfusion (RR 0.81, 95%CI [0.70 to 0.93]), wound infection (RR 0.66, 95%CI [0.47 to 0.92]) and acute renal failure (RR 0.65, 95%CI [0.46 to 0.93]). However, minimally invasive approaches had longer operative time, cross-clamp, and bypass times (SMD 0.47, 95%CI [0.22 to 0.72], SMD 0.27, 95%CI [0.07 to 0.48], and SMD 0.37, 95%CI [0.20 to 0.45], respectively). There were no differences between the two groups in blood loss, endocarditis, cardiac tamponade, stroke, arrhythmias, pneumonia, pneumothorax, bleeding reoperation, tracheostomy, hemodialysis, or myocardial infarction (all P>0.05). Conclusion: Current evidence showed higher safety and better operative outcomes with minimally invasive aortic valve replacement compared to the conventional approach. Future RCTs with long-term follow-ups are recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aortic%20replacement" title="aortic replacement">aortic replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=minimally%20invasive" title=" minimally invasive"> minimally invasive</a>, <a href="https://publications.waset.org/abstracts/search?q=sternotomy" title=" sternotomy"> sternotomy</a>, <a href="https://publications.waset.org/abstracts/search?q=mini-sternotomy" title=" mini-sternotomy"> mini-sternotomy</a>, <a href="https://publications.waset.org/abstracts/search?q=aortic%20valve" title=" aortic valve"> aortic valve</a>, <a href="https://publications.waset.org/abstracts/search?q=meta%20analysis" title=" meta analysis"> meta analysis</a> </p> <a href="https://publications.waset.org/abstracts/157928/minimally-invasive-versus-conventional-sternotomy-for-aortic-valve-replacement-a-systematic-review-and-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157928.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">121</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">822</span> The OverStitch and OverStitch SX Endoscopic Suturing System in Bariatric Surgery, Closing Perforations and Fistulas and Revision Procedures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Tayefeh%20Norooz">Mohammad Tayefeh Norooz</a>, <a href="https://publications.waset.org/abstracts/search?q=Amirhossein%20Kargarzadeh"> Amirhossein Kargarzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Overweight and obesity as an abnormality are health threatening factors. Body mass index (BMI) above 25 is referred to as overweight and above 30 as obese. Apollo Endosurgery, Inc., a pioneering company in endoscopy surgeries, is poised to revolutionize patient care with its minimally invasive treatment options. Some product solutions are designed to improve patient outcomes and redefine the future of healthcare. Weight gain post-weight-loss surgery may stem from an enlarged stomach opening, reducing fullness and increasing food intake. Apollo Endosurgery's OverStitch system, a minimally invasive approach, addresses this by using sutures to reduce stomach opening size. This reflects Apollo's commitment to transformative improvements in healing endoscopy, emphasizing a shift towards minimally invasive options. The system's versatility and precision in full-thickness suturing offer treatment alternatives, exemplified in applications like Endoscopic Sleeve Gastroplasty for reshaping obesity management. Apollo’s dedication to pioneering advancements suggests ongoing breakthroughs in minimally invasive surgery, positioning the OverStitch systems as a testament to innovation in patient care. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apollo%20endosurgery" title="apollo endosurgery">apollo endosurgery</a>, <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20sleeve%20gastroplasty" title=" endoscopic sleeve gastroplasty"> endoscopic sleeve gastroplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=weight%20loss%20system" title=" weight loss system"> weight loss system</a>, <a href="https://publications.waset.org/abstracts/search?q=overstitch%20endoscopic%20suturing%20system" title=" overstitch endoscopic suturing system"> overstitch endoscopic suturing system</a>, <a href="https://publications.waset.org/abstracts/search?q=therapeutic" title=" therapeutic"> therapeutic</a>, <a href="https://publications.waset.org/abstracts/search?q=perforations" title=" perforations"> perforations</a>, <a href="https://publications.waset.org/abstracts/search?q=fistula" title=" fistula"> fistula</a> </p> <a href="https://publications.waset.org/abstracts/184878/the-overstitch-and-overstitch-sx-endoscopic-suturing-system-in-bariatric-surgery-closing-perforations-and-fistulas-and-revision-procedures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184878.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">63</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">821</span> Predictors of Clinical Failure After Endoscopic Lumbar Spine Surgery During the Initial Learning Curve</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Scherman">Daniel Scherman</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Madani"> Daniel Madani</a>, <a href="https://publications.waset.org/abstracts/search?q=Shanu%20Gambhir"> Shanu Gambhir</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Ling%20Zhixing"> Marcus Ling Zhixing</a>, <a href="https://publications.waset.org/abstracts/search?q=Yingda%20Li"> Yingda Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: This study aims to identify clinical factors that may predict failed endoscopic lumbar spine surgery to guide surgeons with patient selection during the initial learning curve. Methods: This is an Australasian prospective analysis of the first 105 patients to undergo lumbar endoscopic spine decompression by 3 surgeons. Modified MacNab outcomes, Oswestry Disability Index (ODI) and Visual Analogue Score (VAS) scores were utilized to evaluate clinical outcomes at 6 months postoperatively. Descriptive statistics and Anova t-tests were performed to measure statistically significant (p<0.05) associations between variables using GraphPad Prism v10. Results: Patients undergoing endoscopic lumbar surgery via an interlaminar or transforaminal approach have overall good/excellent modified MacNab outcomes and a significant reduction in post-operative VAS and ODI scores. Regardless of the anatomical location of disc herniations, good/excellent modified MacNab outcomes and significant reductions in VAS and ODI were reported post-operatively; however, not in patients with calcified disc herniations. Patients with central and foraminal stenosis overall reported poor/fair modified MacNab outcomes. However, there were significant reductions in VAS and ODI scores post-operatively. Patients with subarticular stenosis or an associated spondylolisthesis reported good/excellent modified MacNab outcomes and significant reductions in VAS and ODI scores post-operatively. Patients with disc herniation and concurrent degenerative stenosis had generally poor/fair modified MacNab outcomes. Conclusion: The outcomes of endoscopic spine surgery are encouraging, with a low complication and reoperation rate. However, patients with calcified disc herniations, central canal stenosis or a disc herniation with concurrent degenerative stenosis present challenges during the initial learning curve and may benefit from traditional open or other minimally invasive techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=complications" title="complications">complications</a>, <a href="https://publications.waset.org/abstracts/search?q=lumbar%20disc%20herniation" title=" lumbar disc herniation"> lumbar disc herniation</a>, <a href="https://publications.waset.org/abstracts/search?q=lumbar%20endoscopic%20spine%20surgery" title=" lumbar endoscopic spine surgery"> lumbar endoscopic spine surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=predictors%20of%20failed%20endoscopic%20spine%20surgery" title=" predictors of failed endoscopic spine surgery"> predictors of failed endoscopic spine surgery</a> </p> <a href="https://publications.waset.org/abstracts/181406/predictors-of-clinical-failure-after-endoscopic-lumbar-spine-surgery-during-the-initial-learning-curve" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181406.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">154</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">820</span> Lateral Retroperitoneal Transpsoas Approach: A Practical Minimal Invasive Surgery Option for Treating Pyogenic Spondylitis of the Lumbar Vertebra</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sundaresan%20Soundararajan">Sundaresan Soundararajan</a>, <a href="https://publications.waset.org/abstracts/search?q=Chor%20Ngee%20Tan"> Chor Ngee Tan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Pyogenic spondylitis, otherwise treated conservatively with long term antibiotics, would require surgical debridement and reconstruction in about 10% to 20% of cases. The classical approach adopted many surgeons have always been anterior approach in ensuring thorough and complete debridement. This, however, comes with high rates of morbidity due to the nature of its access. Direct lateral retroperitoneal approach, which has been growing in usage in degenerative lumbar diseases, has the potential in treating pyogenic spondylitis with its ease of approach and relatively low risk of complications. Aims/Objectives: The objective of this study was to evaluate the effectiveness and clinical outcome of using lateral approach surgery in the surgical management of pyogenic spondylitis of the lumbar spine. Methods: Retrospective chart analysis was done on all patients who presented with pyogenic spondylitis (lumbar discitis/vertebral osteomyelitis) and had undergone direct lateral retroperitoneal lumbar vertebral debridement and posterior instrumentation between 2014 and 2016. Data on blood loss, surgical operating time, surgical complications, clinical outcomes and fusion rates were recorded. Results: A total of 6 patients (3 male and 3 female) underwent this procedure at a single institution by a single surgeon during the defined period. One patient presented with infected implant (PLIF) and vertebral osteomyelitis while the other five presented with single level spondylodiscitis. All patients underwent lumbar debridement, iliac strut grafting and posterior instrumentation (revision of screws for infected PLIF case). The mean operating time was 308.3 mins for all 6 cases. Mean blood loss was reported at 341cc (range from 200cc to 600cc). Presenting symptom of back pain resolved in all 6 cases while 2 cases that presented with lower limb weakness had improvement of neurological deficits. One patient had dislodged strut graft while performing posterior instrumentation and needed graft revision intraoperatively. Infective markers normalized for all patients subsequently. All subjects also showed radiological evidence of fusion on 6 months follow up. Conclusions: Lateral approach in treating pyogenic spondylitis is a viable option as it allows debridement and reconstruction without the risk that comes with other anterior approaches. It allows efficient debridement, short surgical time, moderate blood loss and low risk of vascular injuries. Clinical outcomes and fusion rates by this approach also support its use as practical MIS option surgery for such infection cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lateral%20approach" title="lateral approach">lateral approach</a>, <a href="https://publications.waset.org/abstracts/search?q=minimally%20invasive" title=" minimally invasive"> minimally invasive</a>, <a href="https://publications.waset.org/abstracts/search?q=pyogenic%20spondylitis" title=" pyogenic spondylitis"> pyogenic spondylitis</a>, <a href="https://publications.waset.org/abstracts/search?q=XLIF" title=" XLIF"> XLIF</a> </p> <a href="https://publications.waset.org/abstracts/75844/lateral-retroperitoneal-transpsoas-approach-a-practical-minimal-invasive-surgery-option-for-treating-pyogenic-spondylitis-of-the-lumbar-vertebra" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75844.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">819</span> Clinical Outcomes and Surgical Complications in Patients with Cervical Disk Degeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mirzashahi%20Babak">Mirzashahi Babak</a>, <a href="https://publications.waset.org/abstracts/search?q=Mansouri%20Pejman"> Mansouri Pejman</a>, <a href="https://publications.waset.org/abstracts/search?q=Najafi%20Arvin"> Najafi Arvin</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzan%20Mahmoud"> Farzan Mahmoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: There are several surgical treatment choices for cervical spondylotic myelopathy (CSM). The aim of this study is to evaluate clinical outcomes and surgical complications in patients with cervical disk degeneration (CDD) undergoing either anterior cervical discectomy with or without fusion or cervical laminectomy and fusion. Methods: This prospective case series study included 45 consecutive patients with cervical spondylotic myelopathy between January 2010 and November 2014. There were 28 males and 17 females, with a mean age of 47 (range 37-68) years. The mean clinical follow-up was 14 months (range 3-24 months). The Neck Disability Index (NDI), visual analog scale (VAS) neck and arm pain, Short Form-36 (SF-36) were used as the functional outcome measurements. All of the complications in our patients were recorded. Results: In our study group, 26 patients underwent only one or two level anterior cervical discectomy. Ten patients underwent anterior cervical discectomy and fusion (ACDF) and nine cases underwent posterior laminectomy and fusion. We have found a statistically significant improvement between mean preoperative (29, range 19-43) and postoperative (7, range 0-12) NDI scores following surgery (P < 0.05). Also, there was a statistically significant difference between pre and post-operative VAS and SF-36 score (p < 0.05). There was a 7% overall complication rate (n = 3). The only complication in our patients was surgical site cellulitis which has been managed with oral antibiotic therapy. Conclusion: Both anterior cervical discectomy with or without fusion or posterior laminectomy and fusion are safe and efficacious treatment options for the management of CSM. The clinical outcomes seem to be fairly reproducible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cervical" title="cervical">cervical</a>, <a href="https://publications.waset.org/abstracts/search?q=myelopathy" title=" myelopathy"> myelopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=discectomy" title=" discectomy"> discectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=fusion" title=" fusion"> fusion</a>, <a href="https://publications.waset.org/abstracts/search?q=laminectomy" title=" laminectomy"> laminectomy</a> </p> <a href="https://publications.waset.org/abstracts/37427/clinical-outcomes-and-surgical-complications-in-patients-with-cervical-disk-degeneration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37427.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">350</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">818</span> Lumbar Punctures: Re-Audit of Procedure Documentation Following the Introduction of a Standardised Procedure Checklist</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hayley%20Lawrence">Hayley Lawrence</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabi%20Shah"> Nabi Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Dyer"> Sarah Dyer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aims: Lumbar punctures are a common bedside procedure performed in acute medicine. Published guidance exists on the standardised documentation of invasive procedures in order to reduce the risk of complications. The audit aim was to assess current standards of documentation in accordance with both the GMC and the National Standards for Invasive Procedures guidelines. A second cycle was conducted after introducing a standardised sticker created using current guidelines. This would assess whether the sticker improved documentation, aiming for 100% standard in each step of the procedure. Methods: An initial prospective audit of current practice was conducted over a 3-month period. Patients were identified by their presenting complaints and by colleagues assessing acute medical patients. Initial findings were presented locally, and a further prospective audit was conducted following the implementation of a standardised sticker. Results: 19 lumbar punctures were included in the first cycle and 13 procedures in the second. Pre-procedure documentation was collected for each cycle, whereby documentation of ‘Indication’ improved from 5.3% to 84.6%, ‘Consent’ from 84.2% to 100%, ‘Coagulopathy’ from 0% to 61.5%, ‘Drug Chart checked’ from 0% to 100%, ‘Position of patient’ from 26.3% to 100% and use of ‘Aseptic Technique’ from 83.3% to 100% from the first to the second cycle respectively. ‘Level of Doctor’ and ‘Supervision’ decreased from 53% to 31% and 53% to 46%, respectively, in the second cycle. Documentation of the procedure itself also demonstrated improvements, with ‘Level of Insertion’ 15.8% to 100%, ‘Name of Antiseptic Used’ 11.1% to 69.2%, ‘Local Anaesthetic Used’ 26.3% to 53.8%, ‘Needle Gauge’ 42.1% to 76.9%, ‘Number of Attempts’ 78.9% to 100% and ‘Traumatic/Atraumatic’ procedure 26.3% to 92.3%, respectively. A similar number of opening pressures were documented in each cycle at 57.9% and 53.8%, respectively, but its documentation was deemed ‘Not Applicable’ in a higher number of patients in the second cycle. Post-procedure documentation improved, with ‘Number of Samples obtained’ increasing from 52.6% to 92.3% and documentation of ‘Immediate Complications’ increasing from 78.9% to 100%. ‘Dressing Applied’ was poorly documented in the first cycle at 16.7%. This was not included on the standardised sticker, resulting in 0% documentation in the second cycle. Documentation of Clinicians’ Name and Bleep reduced from 63.2% to 15.4%, but when the name only was analysed, this increased to 84.6%. Conclusions: Standardised stickers for lumbar punctures do improve documentation and hence should result in improved patient safety. There is still room for improvement to reach 100% standard in each area, especially with respect to the clinician’s name and contact details being documented. Final adjustments will be made to the sticker before being included in a lumbar puncture kit, which will be made readily available in the acute medical wards. Future audits could be extended to include other common bedside procedures performed in acute medicine to ensure documentation of all these procedures reaches 100% standard. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=invasive%20procedure" title="invasive procedure">invasive procedure</a>, <a href="https://publications.waset.org/abstracts/search?q=lumbar%20puncture" title=" lumbar puncture"> lumbar puncture</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20record%20keeping" title=" medical record keeping"> medical record keeping</a>, <a href="https://publications.waset.org/abstracts/search?q=procedure%20checklist" title=" procedure checklist"> procedure checklist</a>, <a href="https://publications.waset.org/abstracts/search?q=procedure%20documentation" title=" procedure documentation"> procedure documentation</a>, <a href="https://publications.waset.org/abstracts/search?q=standardised%20documentation" title=" standardised documentation"> standardised documentation</a> </p> <a href="https://publications.waset.org/abstracts/147379/lumbar-punctures-re-audit-of-procedure-documentation-following-the-introduction-of-a-standardised-procedure-checklist" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147379.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">103</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">817</span> An Innovative Non-Invasive Method To Improve The Stability Of Orthodontic Implants: A Pilot Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dr.">Dr.</a>, <a href="https://publications.waset.org/abstracts/search?q=Suchita%20Daokar"> Suchita Daokar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Successful orthodontic treatment has always relied on anchorage. The stability of the implants depends on bone quantity, mini-implant design, and placement conditions. Out of the various methods of gaining stability, Platelet concentrations are gaining popularity for various reasons. PRF is a minimally invasive method, and there are various studies that has shown its role in enhancing the stability of general implants. However, there is no literature found regarding the effect of PRF in enhancing the stability of the orthodontic implant. Therefore, this study aimed to evaluate and assess the efficacy of PRF on the stability of the orthodontic implant. Methods: The study comprised of 9 subjects aged above 18 years of age. The split mouth technique was used; Group A (where implants were coated before insertion) and group B (implant were normally inserted). The stability of the implant was measured using resonance frequency analysis at insertion (T0), 24 hours (T1), 2 weeks (T2), at 4 weeks (T3), at 6 weeks (T4), and 8 weeks (T5) after insertion. Result: Statistically significant findings were found when group A was compared to group B using ANOVA test (p<0.05). The stability of the implant of group A at each time interval was greater than group B. The implant stability was high at T0 and reduces at T2, and increasing through T3 to T5. The stability was highest at T5. Conclusion: A chairside, minimally invasive procedure ofPRF coating on implants have shown promising results in improving the stability of orthodontic implants and providing scope for future studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Orthodontic%20implants" title="Orthodontic implants">Orthodontic implants</a>, <a href="https://publications.waset.org/abstracts/search?q=stablity" title=" stablity"> stablity</a>, <a href="https://publications.waset.org/abstracts/search?q=resonance%20Frequency%20Analysis" title=" resonance Frequency Analysis"> resonance Frequency Analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=pre" title=" pre"> pre</a> </p> <a href="https://publications.waset.org/abstracts/140299/an-innovative-non-invasive-method-to-improve-the-stability-of-orthodontic-implants-a-pilot-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140299.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">816</span> Development of Anterior Lumbar Interbody Fusion (ALIF) Peek Cage Based on the Korean Lumbar Anatomical Information</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chang%20Soo%20Chon">Chang Soo Chon</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheol%20Woong%20Ko"> Cheol Woong Ko</a>, <a href="https://publications.waset.org/abstracts/search?q=Han%20Sung%20Kim"> Han Sung Kim </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to develop an anterior lumbar interbody fusion (ALIF) PEEK cage suitable for Korean people.

Therefore, surgeons need efficient tactile sensing like determining the hardness of contact tissue for investigating the patient’s health condition. In such a case, MIS tactile sensors are preferred to be able to provide force/pressure sensing, force position, lump detection, and softness sensing. Among different pressure sensor technologies, the piezoelectric operating principle is the fittest for MIS’s instruments, such as catheters. Using PVDF with its copolymer, TrFE, as a piezoelectric material, is a common method of design and fabrication of a tactile sensor due to its ease of implantation and biocompatibility. In this research, PVDF-TrFE polymer is deposited via spin-coating method and treated with various post-deposition processes to investigate its piezoelectricity and amount of electroactive β phase. These processes include different post thermal annealing, the effect of spin-coating speed, different layer of deposition, and the presence of additional hydrate salt. According to FTIR spectroscopy and SEM images, the amount of the β phase and porosity of each sample is determined. In addition, the optimum experimental study is established by considering every aspect of the fabrication process. This study clearly shows the effective way of deposition and fabrication of a tactile PVDF-TrFE based sensor and an enhancement methodology to have a higher β phase and piezoelectric constant in order to have a better sense of touch at the end effector of biomedical devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%CE%B2%20phase" title="β phase">β phase</a>, <a href="https://publications.waset.org/abstracts/search?q=minimally%20invasive%20surgery" title=" minimally invasive surgery"> minimally invasive surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=piezoelectricity" title=" piezoelectricity"> piezoelectricity</a>, <a href="https://publications.waset.org/abstracts/search?q=PVDF-TrFE" title=" PVDF-TrFE"> PVDF-TrFE</a>, <a href="https://publications.waset.org/abstracts/search?q=tactile%20sensor" title=" tactile sensor"> tactile sensor</a> </p> <a href="https://publications.waset.org/abstracts/122781/design-and-fabrication-of-piezoelectric-tactile-sensor-by-deposition-of-pvdf-trfe-with-spin-coating-method-for-minimally-invasive-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122781.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">122</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">814</span> Body Shape Control of Magnetic Soft Continuum Robots with PID Controller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20H.%20Korayem">M.

However, one of the main challenges in this field is damage to the vascular structure caused by unwanted stress on the vessel wall and deformation of the vessel due to improper control of the shape of the robot body during surgery. Therefore, this article proposes an approach for controlling the form of a magnetic, soft, continuous robot body using a PID controller. The magnetic soft continuous robot is modelled using Cosserat theory in static mode and solved numerically. The designed controller adjusts the position of each part of the robot to match the desired shape. The PID controller is considered to minimize the robot's contact with the vessel wall and prevent unwanted vessel deformation. The simulation results confirmed the accuracy of the numerical solution of the static Cosserat model. Also, they showed the effectiveness of the proposed contouring method in achieving the desired shape with a maximum error of about 0.3 millimetres. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PID" title="PID">PID</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20soft%20continuous%20robot" title=" magnetic soft continuous robot"> magnetic soft continuous robot</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20robot%20shape%20control" title=" soft robot shape control"> soft robot shape control</a>, <a href="https://publications.waset.org/abstracts/search?q=Cosserat%20theory" title=" Cosserat theory"> Cosserat theory</a>, <a href="https://publications.waset.org/abstracts/search?q=minimally%20invasive%20surgery" title=" minimally invasive surgery"> minimally invasive surgery</a> </p> <a href="https://publications.waset.org/abstracts/175469/body-shape-control-of-magnetic-soft-continuum-robots-with-pid-controller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175469.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">109</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">813</span> Early and Mid-Term Results of Anesthetic Management of Minimal Invasive Coronary Artery Bypass Grafting Using One Lung Ventilation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Devendra%20Gupta">Devendra Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20P.%20Ambesh"> S.

Minimally invasive direct coronary artery bypass (MIDCAB) provides many anesthetic challenges including one lung ventilation (OLV), managing myocardial ischemia, and pain. We present an early and midterm result of the use of this technique with OLV. Method: We enrolled 62 patients for analysis operated between 2008 and 2012. Patients were anesthetized and left endobronchial tube was placed. During the procedure left lung was isolated and one lung ventilation was maintained through right lung. Operation was performed utilizing off pump technique of coronary artery bypass grafting through a minimal invasive incision. Left internal mammary artery graft was done for single vessel disease and radial artery was utilized for other grafts if required. Postoperative ventilation was done with single lumen endotracheal tube. Median follow-up is 2.5 years (6 months to 4 years). Results: Median age was 58.5 years (41-77) and all were male. Single vessel disease was present in 36, double vessel in 24 and triple vessel disease in 2 patients. All the patients had normal left ventricular size and function. In 2 cases difficulty were encounter in placement of endobronchial tube. In 1 case cuff of endobronchial tube was ruptured during intubation. High airway pressure was developed on OLV in 1 case and surgery was accomplished with two lung anesthesia with low tidal volume. Mean postoperative ventilation time was 14.4 hour (11-22). There was no perioperative and 30 day mortality. Conversion to median sternotomy to complete the operation was done in 3.23% (2 out of 62 patients). One patient had acute myocardial infarction postoperatively and there were no deaths during follow-up. Conclusion: MICABG is a safe and effective method of revascularization with OLV in low risk candidates for coronary artery bypass grafting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MIDCABG" title="MIDCABG">MIDCABG</a>, <a href="https://publications.waset.org/abstracts/search?q=one%20lung%20ventilation" title=" one lung ventilation"> one lung ventilation</a>, <a href="https://publications.waset.org/abstracts/search?q=coronary%20artery%20bypass%20grafting" title=" coronary artery bypass grafting"> coronary artery bypass grafting</a>, <a href="https://publications.waset.org/abstracts/search?q=endobronchial%20tube" title=" endobronchial tube"> endobronchial tube</a> </p> <a href="https://publications.waset.org/abstracts/12483/early-and-mid-term-results-of-anesthetic-management-of-minimal-invasive-coronary-artery-bypass-grafting-using-one-lung-ventilation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12483.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">425</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">812</span> Biomechanical Evaluation for Minimally Invasive Lumbar Decompression: Unilateral Versus Bilateral Approaches</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yi-Hung%20Ho">Yi-Hung Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih-Wei%20Wang"> Chih-Wei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih-Hsien%20Chen"> Chih-Hsien Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih-Han%20Chang"> Chih-Han Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Unilateral laminotomy and bilateral laminotomies were successful decompressions methods for managing spinal stenosis that numerous studies have reported. Thus, unilateral laminotomy was rated technically much more demanding than bilateral laminotomies, whereas the bilateral laminotomies were associated with a positive benefit to reduce more complications. There were including incidental durotomy, increased radicular deficit, and epidural hematoma. However, no relative biomechanical analysis for evaluating spinal instability treated with unilateral and bilateral laminotomies. Therefore, the purpose of this study was to compare the outcomes of different decompressions methods by experimental and finite element analysis. Three porcine lumbar spines were biomechanically evaluated for their range of motion, and the results were compared following unilateral or bilateral laminotomies. The experimental protocol included flexion and extension in the following procedures: intact, unilateral, and bilateral laminotomies (L2–L5). The specimens in this study were tested in flexion (8 Nm) and extension (6 Nm) of pure moment. Spinal segment kinematic data was captured by using the motion tracking system. A 3D finite element lumbar spine model (L1-S1) containing vertebral body, discs, and ligaments were constructed. This model was used to simulate the situation of treating unilateral and bilateral laminotomies at L3-L4 and L4-L5. The bottom surface of S1 vertebral body was fully geometrically constrained in this study. A 10 Nm pure moment also applied on the top surface of L1 vertebral body to drive lumbar doing different motion, such as flexion and extension. The experimental results showed that in the flexion, the ROMs (±standard deviation) of L3–L4 were 1.35±0.23, 1.34±0.67, and 1.66±0.07 degrees of the intact, unilateral, and bilateral laminotomies, respectively. The ROMs of L4–L5 were 4.35±0.29, 4.06±0.87, and 4.2±0.32 degrees, respectively. No statistical significance was observed in these three groups (P>0.05). In the extension, the ROMs of L3–L4 were 0.89±0.16, 1.69±0.08, and 1.73±0.13 degrees, respectively. In the L4-L5, the ROMs were 1.4±0.12, 2.44±0.26, and 2.5±0.29 degrees, respectively. Significant differences were observed among all trials, except between the unilateral and bilateral laminotomy groups. At the simulation results portion, the similar results were discovered with the experiment. No significant differences were found at L4-L5 both flexion and extension in each group. Only 0.02 and 0.04 degrees variation were observed during flexion and extension between the unilateral and bilateral laminotomy groups. In conclusions, the present results by finite element analysis and experimental reveal that no significant differences were observed during flexion and extension between unilateral and bilateral laminotomies in short-term follow-up. From a biomechanical point of view, bilateral laminotomies seem to exhibit a similar stability as unilateral laminotomy. In clinical practice, the bilateral laminotomies are likely to reduce technical difficulties and prevent perioperative complications; this study proved this benefit through biomechanical analysis. The results may provide some recommendations for surgeons to make the final decision. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unilateral%20laminotomy" title="unilateral laminotomy">unilateral laminotomy</a>, <a href="https://publications.waset.org/abstracts/search?q=bilateral%20laminotomies" title=" bilateral laminotomies"> bilateral laminotomies</a>, <a href="https://publications.waset.org/abstracts/search?q=spinal%20stenosis" title=" spinal stenosis"> spinal stenosis</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis "> finite element analysis </a> </p> <a href="https://publications.waset.org/abstracts/36871/biomechanical-evaluation-for-minimally-invasive-lumbar-decompression-unilateral-versus-bilateral-approaches" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36871.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">399</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">811</span> A Decision Support System to Detect the Lumbar Disc Disease on the Basis of Clinical MRI </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yavuz%20Unal">Yavuz Unal</a>, <a href="https://publications.waset.org/abstracts/search?q=Kemal%20Polat"> Kemal Polat</a>, <a href="https://publications.waset.org/abstracts/search?q=H.%20Erdinc%20Kocer"> H.

Standard exposure factors such as kV, mAs and FFD used for imaging the Lumbar spine anthropomorphic phantom obtained from average exposure factors that were used with CR in five radiology centres. Lumbar spine phantom was imaged using CR and DR systems. Entrance surface air kerma (ESAK) was calculated X-ray tube output and patient exposure factor. Images were evaluated using visual grading system based on the European Guidelines on Quality Criteria for diagnostic radiographic images. The ESAK corresponding to each image was measured at the surface of the phantom. Six experienced specialists evaluated hard copies of all the images, the image score (IS) was calculated for each image by finding the average score of the Six evaluators. The IS value also was used to determine whether an image was diagnostically acceptable. The optimum recommended exposure factors founded here for Lumbar spine PA and Lumbar spine LAT, with respectively (80 kVp,25 mAs at 100 cm FFD) and (75 kVp,15 mAs at 100 cm FFD) for CR system, and (80 kVp,15 mAs at100 cm FFD) and (75 kVp,10 mAs at 100 cm FFD) for DR system. For Lumbar spine PA, the lowest ESAK value required to obtain a diagnostically acceptable image were 0.80 mGy for DR and 1.20 mGy for CR systems. Similarly for Lumbar spine LAT projection, the lowest ESAK values to obtain a diagnostically acceptable image were 0.62 mGy for DR and 0.76 mGy for CR systems. At standard kVp and mAs values, the image quality did not vary significantly between the CR and the DR system, but at higher kVp and mAs values, the DR images were found to be of better quality than CR images. In addition, the lower limit of entrance skin dose consistent with diagnostically acceptable DR images was 40% lower than that for CR images. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=image%20quality" title="image quality">image quality</a>, <a href="https://publications.waset.org/abstracts/search?q=dosimetry" title=" dosimetry"> dosimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20protection" title=" radiation protection"> radiation protection</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20radiography" title=" digital radiography"> digital radiography</a>, <a href="https://publications.waset.org/abstracts/search?q=computed%20radiography" title=" computed radiography"> computed radiography</a> </p> <a href="https://publications.waset.org/abstracts/185317/image-quality-and-dose-optimisations-in-digital-and-computed-radiography-x-ray-radiography-using-lumbar-spine-phantom" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185317.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">50</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">809</span> A Minimally Invasive Approach Using Bio-Miniatures Implant System for Full Arch Rehabilitation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omid%20Allan">Omid Allan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The advent of ultra-narrow diameter implants initially offered an alternative to wider conventional implants. However, their design limitations have restricted their applicability primarily to overdentures and cement-retained fixed prostheses, often with unpredictable long-term outcomes. The introduction of the new Miniature Implants has revolutionized the field of implant dentistry, leading to a more streamlined approach. The utilization of Miniature Implants has emerged as a promising alternative to the traditional approach that entails the traumatic sequential bone drilling procedures and the use of conventional implants for full and partial arch restorations. The innovative "BioMiniatures Implant System serves as a groundbreaking bridge connecting mini implants with standard implant systems. This system allows practitioners to harness the advantages of ultra-small implants, enabling minimally invasive insertion and facilitating the application of fixed screw-retained prostheses, which were only available to conventional wider implant systems. This approach streamlines full and partial arch rehabilitation with minimal or even no bone drilling, significantly reducing surgical risks and complications for clinicians while minimizing patient morbidity. The ultra-narrow diameter and self-advancing features of these implants eliminate the need for invasive and technically complex procedures such as bone augmentation and guided bone regeneration (GBR), particularly in cases involving thin alveolar ridges. Furthermore, the absence of a microcap between the implant and abutment eliminates the potential for micro-leakage and micro-pumping effects, effectively mitigating the risk of marginal bone loss and future peri-implantitis. The cumulative experience of restoring over 50 full and partial arch edentulous cases with this system has yielded an outstanding success rate exceeding 97%. The long-term success with a stable marginal bone level in the study firmly establishes these implants as a dependable alternative to conventional implants, especially for full arch rehabilitation cases. Full arch rehabilitation with these implants holds the promise of providing a simplified solution for edentulous patients who typically present with atrophic narrow alveolar ridges, eliminating the need for extensive GBR and bone augmentation to restore their dentition with fixed prostheses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mini-implant" title="mini-implant">mini-implant</a>, <a href="https://publications.waset.org/abstracts/search?q=biominiatures" title=" biominiatures"> biominiatures</a>, <a href="https://publications.waset.org/abstracts/search?q=miniature%20implants" title=" miniature implants"> miniature implants</a>, <a href="https://publications.waset.org/abstracts/search?q=minimally%20invasive%20dentistry" title=" minimally invasive dentistry"> minimally invasive dentistry</a>, <a href="https://publications.waset.org/abstracts/search?q=full%20arch%20rehabilitation" title=" full arch rehabilitation"> full arch rehabilitation</a> </p> <a href="https://publications.waset.org/abstracts/174089/a-minimally-invasive-approach-using-bio-miniatures-implant-system-for-full-arch-rehabilitation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174089.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">74</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">808</span> Bionaut™: A Breakthrough Robotic Microdevice to Treat Non-Communicating Hydrocephalus in Both Adult and Pediatric Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suehyun%20Cho">Suehyun Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Darrell%20Harrington"> Darrell Harrington</a>, <a href="https://publications.waset.org/abstracts/search?q=Florent%20Cros"> Florent Cros</a>, <a href="https://publications.waset.org/abstracts/search?q=Olin%20Palmer"> Olin Palmer</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Caputo"> John Caputo</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Kardosh"> Michael Kardosh</a>, <a href="https://publications.waset.org/abstracts/search?q=Eran%20Oren"> Eran Oren</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20Loudon"> William Loudon</a>, <a href="https://publications.waset.org/abstracts/search?q=Alex%20Kiselyov"> Alex Kiselyov</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Shpigelmacher"> Michael Shpigelmacher</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bionaut Labs, LLC is developing a minimally invasive robotic microdevice designed to treat non-communicating hydrocephalus in both adult and pediatric patients. The device utilizes biocompatible microsurgical particles (Bionaut™) that are specifically designed to safely and reliably perform accurate fenestration(s) in the 3rd ventricle, aqueduct of Sylvius, and/or trapped intraventricular cysts of the brain in order to re-establish normal cerebrospinal fluid flow dynamics and thereby balance and/or normalize intra/intercompartmental pressure. The Bionaut™ is navigated to the target via CSF or brain tissue in a minimally invasive fashion with precise control using real-time imaging. Upon reaching the pre-defined anatomical target, the external driver allows for directing the specific microsurgical action defined to achieve the surgical goal. Notable features of the proposed protocol are i) Bionaut™ access to the intraventricular target follows a clinically validated endoscopy trajectory which may not be feasible via ‘traditional’ rigid endoscopy: ii) the treatment is microsurgical, there are no foreign materials left behind post-procedure; iii) Bionaut™ is an untethered device that is navigated through the subarachnoid and intraventricular compartments of the brain, following pre-designated non-linear trajectories as determined by the safest anatomical and physiological path; iv) Overall protocol involves minimally invasive delivery and post-operational retrieval of the surgical Bionaut™. The approach is expected to be suitable to treat pediatric patients 0-12 months old as well as adult patients with obstructive hydrocephalus who fail traditional shunts or are eligible for endoscopy. Current progress, including platform optimization, Bionaut™ control, and real-time imaging and in vivo safety studies of the Bionauts™ in large animals, specifically the spine and the brain of ovine models, will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bionaut%E2%84%A2" title="Bionaut™">Bionaut™</a>, <a href="https://publications.waset.org/abstracts/search?q=cerebrospinal%20fluid" title=" cerebrospinal fluid"> cerebrospinal fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=CSF" title=" CSF"> CSF</a>, <a href="https://publications.waset.org/abstracts/search?q=fenestration" title=" fenestration"> fenestration</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocephalus" title=" hydrocephalus"> hydrocephalus</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-robot" title=" micro-robot"> micro-robot</a>, <a href="https://publications.waset.org/abstracts/search?q=microsurgery" title=" microsurgery"> microsurgery</a> </p> <a href="https://publications.waset.org/abstracts/131924/bionaut-a-breakthrough-robotic-microdevice-to-treat-non-communicating-hydrocephalus-in-both-adult-and-pediatric-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131924.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">170</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">807</span> Isolated Contraction of Deep Lumbar Paraspinal Muscle with Magnetic Nerve Root Stimulation: A Pilot Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shi-Uk%20Lee">Shi-Uk Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Chae%20Young%20Lim"> Chae Young Lim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: The aim of this study was to evaluate the changes of lumbar deep muscle thickness and cross-sectional area using ultrasonography with magnetic stimulation. Methods: To evaluate the changes of lumbar deep muscle by using magnetic stimulation, 12 healthy volunteers (39.6±10.0 yrs) without low back pain during 3 months participated in this study. All the participants were checked with X-ray and electrophysiologic study to confirm that they had no problems with their back. Magnetic stimulation was done on the L5 and S1 root with figure-eight coil as previous study. To confirm the proper motor root stimulation, the surface electrode was put on the tibialis anterior (L5) and abductor hallucis muscles (S1) and the hot spots of magnetic stimulation were found with 50% of maximal magnetic stimulation and determined the stimulation threshold lowering the magnetic intensity by 5%. Ultrasonography was used to assess the changes of L5 and S1 lumbar multifidus (superficial and deep) cross-sectional area and thickness with maximal magnetic stimulation. Cross-sectional area (CSA) and thickness was evaluated with image acquisition program, ImageJ software (National Institute of Healthy, USA). Wilcoxon signed-rank was used to compare outcomes between before and after stimulations. Results: The mean minimal threshold was 29.6±3.8% of maximal stimulation intensity. With minimal magnetic stimulation, thickness of L5 and S1 deep multifidus (DM) were increased from 1.25±0.20, 1.42±0.23 cm to 1.40±0.27, 1.56±0.34 cm, respectively (P=0.005, P=0.003). CSA of L5 and S1 DM were also increased from 2.26±0.18, 1.40±0.26 cm2 to 2.37±0.18, 1.56±0.34 cm2, respectively (P=0.002, P=0.002). However, thickness of L5 and S1 superficial multifidus (SM) were not changed from 1.92±0.21, 2.04±0.20 cm to 1.91±0.33, 1.96±0.33 cm (P=0.211, P=0.199) and CSA of L5 and S1 were also not changed from 4.29±0.53, 5.48±0.32 cm2 to 4.42±0.42, 5.64±0.38 cm2. With maximal magnetic stimulation, thickness of L5, S1 of DM and SM were increased (L5 DM, 1.29±0.26, 1.46±0.27 cm, P=0.028; L5 SM, 2.01±0.42, 2.24±0.39 cm, P=0.005; S1 DM, 1.29±0.19, 1.67±0.29 P=0.002; S1 SM, 1.90±0.36, 2.30±0.36, P=0.002). CSA of L5, S1 of DM and SM were also increased (all P values were 0.002). Conclusions: Deep lumbar muscles could be stimulated with lumbar motor root magnetic stimulation. With minimal stimulation, thickness and CSA of lumbosacral deep multifidus were increased in this study. Further studies are needed to confirm whether the similar results in chronic low back pain patients are represented. Lumbar magnetic stimulation might have strengthening effect of deep lumbar muscles with no discomfort. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20stimulation" title="magnetic stimulation">magnetic stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=lumbar%20multifidus" title=" lumbar multifidus"> lumbar multifidus</a>, <a href="https://publications.waset.org/abstracts/search?q=strengthening" title=" strengthening"> strengthening</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonography" title=" ultrasonography"> ultrasonography</a> </p> <a href="https://publications.waset.org/abstracts/37453/isolated-contraction-of-deep-lumbar-paraspinal-muscle-with-magnetic-nerve-root-stimulation-a-pilot-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37453.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">371</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">806</span> Design of a Lumbar Interspinous Process Fixation Device for Minimizing Soft Tissue Removal and Operation Time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minhyuk%20Heo">Minhyuk Heo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jihwan%20Yun"> Jihwan Yun</a>, <a href="https://publications.waset.org/abstracts/search?q=Seonghun%20Park"> Seonghun Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It has been reported that intervertebral fusion surgery, which removes most of the ligaments and muscles of the spine, increases the degenerative disease in adjacent spinal segments. Therefore, it is required to develop a lumbar interspinous process fixation device that minimizes the risks and side effects from the surgery. The objective of the current study is to design an interspinous process fixation device with simple structures in order to minimize soft tissue removal and operation time during intervertebral fusion surgery. For the design concepts of a lumbar fixation device, the principle of the ratchet was first applied on the joining parts of the device in order to shorten the operation time. The coil spring structure was selected for connecting parts between the spinous processes so that a normal range of motion in spinal segments is preserved and degenerative spinal diseases are not developed in the adjacent spinal segments. The stiffness of the spring was determined not to interrupt the motion of a lumbar spine. The designed value of the spring stiffness allows the upper part of the spring to move ~10° which is higher than the range of flexion and extension for normal lumbar spine (6°-8°), when a moment of 10Nm is applied on the upper face of L1. A finite element (FE) model composed of L1 to L5 lumbar spines was generated to verify the mechanical integrity and the dynamic stability of the designed lumbar fixation device and to further optimize the lumbar fixation device. The FE model generated above produced the same pressure value on intervertebral disc and dynamic behavior as the normal intact model reported in the literature. The consistent results from this comparison validates the accuracy in the modeling of the current FE model. Currently, we are trying to generate an abnormal model with defects in one or more components of the normal FE model above. Then, the mechanical integrity and the dynamic stability of the designed lumbar fixation device will be analyzed after being installed in the abnormal model and then the lumbar fixation device will be further optimized. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lumbar%20interspinous%20process%20fixation%20device" title="lumbar interspinous process fixation device">lumbar interspinous process fixation device</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=lumbar%20spine" title=" lumbar spine"> lumbar spine</a>, <a href="https://publications.waset.org/abstracts/search?q=kinematics" title=" kinematics"> kinematics</a> </p> <a href="https://publications.waset.org/abstracts/60372/design-of-a-lumbar-interspinous-process-fixation-device-for-minimizing-soft-tissue-removal-and-operation-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60372.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">228</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">805</span> Minimal Invasive Esophagectomy for Esophageal Cancer: An Institutional Review From a Dedicated Centre of Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nighat%20Bakhtiar">Nighat Bakhtiar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Raza%20Khan"> Ali Raza Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahid%20Khan%20Khattak"> Shahid Khan Khattak</a>, <a href="https://publications.waset.org/abstracts/search?q=Aamir%20Ali%20Syed"> Aamir Ali Syed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Chemoradiation followed by resection has been the standard therapy for resectable (cT1-4aN0-3M0) esophageal carcinoma.

Treatment of hypertensive intracerebral hematoma (ICH) is controversial. Advantage of one surgical method on other has not been established. Recent reports suggest a favorable effect of minimally invasive surgery. We conducted a small comparative study of different surgical methods. Methods. We analyzed the result of surgical treatment of 176 patients with intracerebral hematomas at the age from 41 to 78 years. Men were been113 (64.2%), women - 63 (35.8%). Level of consciousness: conscious -18, lethargy -63, stupor –55, moderate coma - 40. All patients on admission and in the dynamics underwent computer tomography (CT) of the brain. ICH was located in the putamen in 87 cases, thalamus in 19, in the mix area in 50, in the lobar area in 20. Ninety seven patients of them had an intraventricular hemorrhage component. The baseline volume of the ICH was measured according to a bedside method of measuring CT intracerebral hematomas volume. Depending on the intervention of the patients were divided into three groups. Group 1 patients, 90 patients, operated open craniotomy. Level of consciousness: conscious-11, lethargy-33, stupor–18, moderate coma -18. The hemorrhage was located in the putamen in 51, thalamus in 3, in the mix area in 25, in the lobar area in 11. Group 2 patients, 22 patients, underwent smaller craniotomy with endoscopic-assisted evacuation. Level of consciousness: conscious-4, lethargy-9, stupor–5, moderate coma -4. The hemorrhage was located in the putamen in 5, thalamus in 15, in the mix area in 2. Group 3 patients, 64 patients, was conducted minimally invasive removal of intracerebral hematomas using the original device (patent of Russian Federation № 65382). The device - funnel cannula - which after the special markings introduced into the hematoma cavity. Level of consciousness: conscious-3, lethargy-21, stupor–22, moderate coma -18. The hemorrhage was located in the putamen in 31, in the mix area in 23, thalamus in 1, in the lobar area in 9. Results of treatment were evaluated by Glasgow outcome scale. Results. The study showed that the results of surgical treatment in three groups depending on the degree of consciousness, the volume and localization of hematoma. In group 1, good recovery observed in 8 cases (8.9%), moderate disability in 22 (24.4%), severe disability - 17 (18.9%), death-43 (47.8%). In group 2, good recovery observed in 7 cases (31.8%), moderate disability in 7 (31.8%), severe disability - 5 (29.7%), death-7 (31.8%). In group 3, good recovery was observed in 9 cases (14.1%), moderate disability-17 (26.5%), severe disability-19 (29.7%), death-19 (29.7%). Conclusions. The method of using cannulae allowed to abandon from open craniotomy of the majority of patients with putaminal hematomas. Minimally invasive technique reduced the postoperative mortality and improves treatment outcomes of these patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nontraumatic%20intracerebral%20hematoma" title="nontraumatic intracerebral hematoma">nontraumatic intracerebral hematoma</a>, <a href="https://publications.waset.org/abstracts/search?q=minimal%20invasive%20surgical%20technique" title=" minimal invasive surgical technique"> minimal invasive surgical technique</a>, <a href="https://publications.waset.org/abstracts/search?q=funnel%20canula" title=" funnel canula"> funnel canula</a>, <a href="https://publications.waset.org/abstracts/search?q=differentiated%20surcical%20treatment" title=" differentiated surcical treatment"> differentiated surcical treatment</a> </p> <a href="https://publications.waset.org/abstracts/163607/differentiated-surgical-treatment-of-patients-with-nontraumatic-intracerebral-hematomas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163607.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">83</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">803</span> Endoscopic Treatment of Esophageal Injuries Using Vacuum Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Murad%20Gasanov">Murad Gasanov</a>, <a href="https://publications.waset.org/abstracts/search?q=Shagen%20Danielyan"> Shagen Danielyan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Gasanov"> Ali Gasanov</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuri%20Teterin"> Yuri Teterin</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Yartsev"> Peter Yartsev</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Despite the advances made in modern surgery, the treatment of patients with esophageal injuries remains one of the most topical and complex issues. In recent years, high-technology minimally invasive methods, such as endoscopic vacuum therapy (EVT) in the treatment of esophageal injuries. The effectiveness of EVT has been sufficiently studied in case of failure of esophageal anastomoses, however the application of this method in case of mechanical esophageal injuries is limited by a small series of observations, indicating the necessity of additional study. Aim: The aim was to аnalyzed of own experience in the use of endoscopic vacuum therapy (EVT) in a comprehensive examination of patients with esophageal injuries. Methods: We analyzed the results of treatment of 24 patients with mechanical injuries of the esophagus for the period 2019-2021. Complex treatment of patients included the use of minimally invasive technologies, including percutaneous endoscopic gastrostomy (PEG), EVT and video-assisted thoracoscopic debridement. Evaluation of the effectiveness of treatment was carried out using multislice computed tomography (MSCT), endoscopy and laboratory tests. The duration of inpatient treatment and the duration of EVT, the number of system replacements, complications and mortality were taken into account. Result: EVT in patients with mechanical injuries of the esophagus allowed to achieve epithelialization of the esophageal defect in 21 patients (87.5%) in the form of linear scar on the site of perforation or pseudodiverticulum. Complications were noted in 4 patients (16.6%), including bleeding (2) and and esophageal stenosis in the perforation area (2). Lethal outcome was in one observation (4.2%). Conclusion. EVT may be the method of choice in complex treatment in patients with esophageal lesions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=esophagus%20injuries" title="esophagus injuries">esophagus injuries</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20to%20the%20esophagus" title=" damage to the esophagus"> damage to the esophagus</a>, <a href="https://publications.waset.org/abstracts/search?q=perforation%20of%20the%20esophagus" title=" perforation of the esophagus"> perforation of the esophagus</a>, <a href="https://publications.waset.org/abstracts/search?q=spontaneous%20perforation%20of%20the%20esophagus" title=" spontaneous perforation of the esophagus"> spontaneous perforation of the esophagus</a>, <a href="https://publications.waset.org/abstracts/search?q=mediastinitis" title=" mediastinitis"> mediastinitis</a>, <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20vacuum%20therapy" title=" endoscopic vacuum therapy"> endoscopic vacuum therapy</a> </p> <a href="https://publications.waset.org/abstracts/159374/endoscopic-treatment-of-esophageal-injuries-using-vacuum-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159374.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">105</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">802</span> The Correlation between Body Composition and Spinal Alignment in Healthy Young Adults</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ferruh%20%20Taspinar">Ferruh Taspinar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Saracoglu"> Ismail Saracoglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Emrah%20Afsar"> Emrah Afsar</a>, <a href="https://publications.waset.org/abstracts/search?q=Eda%20O.%20%20Okur"> Eda O.

The aim of this study was to investigate the correlation with detailed body composition and spine alignment in healthy young adults. This cross-sectional study was conducted with sixty seven healthy volunteers (37 men and 30 women) whose ages ranged between 19 and 27 years. All participants’ sagittal spinal curvatures of lumbar and thoracic region were measured via Spinal mouse® (Idiag, Fehraltorf, Switzerland). Also, body composition analysis (whole body fat ratio, whole body muscle ratio, abdominal fat ratio, and trunk muscle ratio) estimation by means of bioelectrical impedance was evaluated via Tanita Bc 418 Ma Segmental Body Composition Analyser (Tanita, Japan). Pearson’s correlation was used to analysis among the variables. The mean lumbar lordosis and thoracic kyphosis angles were 21.02°±9.39, 41.50°±7.97, respectively. Statistically analysis showed a significant positive correlation between whole body fat ratio and lumbar lordosis angle (r=0.28, p=0.02). Similarly, there was a positive correlation between abdominal fat ratio and lumbar lordosis angle (r=0.27, p=0.03). The thoracic kyphosis angle showed also positive correlation with whole body fat ratio (r=0.33, p=0.00) and abdominal fat ratio (r=0.40, p=0.01). The whole body muscle ratio showed negative correlation between lumbar lordosis (r=-0.28, p=0.02) and thoracic kyphosis angles (r=-0.33, p=0.00), although there was no statistically correlation between trunk muscle ratio, lumbar and thoracic curvatures (p>0.05). The study demonstrated that an increase of fat ratio and decrease of muscle ratio in abdominal region or whole body shifts the spinal alignment which may adversely affect the spinal loading. Therefore, whole body composition should be taken into account in spine rehabilitation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=body%20composition" title="body composition">body composition</a>, <a href="https://publications.waset.org/abstracts/search?q=lumbar%20lordosis" title=" lumbar lordosis"> lumbar lordosis</a>, <a href="https://publications.waset.org/abstracts/search?q=spinal%20alignment" title=" spinal alignment"> spinal alignment</a>, <a href="https://publications.waset.org/abstracts/search?q=thoracic%20kyphosis" title=" thoracic kyphosis"> thoracic kyphosis</a> </p> <a href="https://publications.waset.org/abstracts/60279/the-correlation-between-body-composition-and-spinal-alignment-in-healthy-young-adults" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60279.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">386</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">801</span> Evaluation of Patients’ Quality of Life After Lumbar Disc Surgery and Movement Limitations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shirin%20Jalili">Shirin Jalili</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramin%20Ghasemi"> Ramin Ghasemi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lumbar microdiscectomy is the most commonly performed spinal surgery strategy; it is regularly performed to lighten the indications and signs of sciatica within the lower back and leg caused by a lumbar disc herniation. This surgery aims to progress leg pain, reestablish function, and enable a return to ordinary day-by-day exercises. Rates of lumbar disc surgery show critical geographic varieties recommending changing treatment criteria among working specialists. Few population-based considers have investigated the hazard of reoperation after disc surgery, and regional or inter specialty varieties within the reoperations are obscure. The conventional approach to recouping from lumbar microdiscectomy has been to restrain bending, lifting, or turning for a least 6 weeks in arrange to anticipate the disc from herniating once more. Traditionally, patients were exhorted to limit post-operative action, which was accepted to decrease the hazard of disc herniation and progressive insecurity. In modern hone, numerous specialists don't limit understanding of postoperative action due to the discernment this practice is pointless. There's a need of thinks about highlighting the result by distinctive scores or parameters after surgery for repetitive circle herniations of the lumbar spine at the starting herniation location.

Methods: This study was a retrospective chart review of 291 patients who underwent lumbar fusion between March 2015 and February 2016 at the Asan Medical Center. Information was extracted from electronic medical records. Postoperative fever was measured at Tmax > 37.7 ℃ and Tmax > 38.3 ℃. The presence of postoperative fever, blood culture, urinary excretion, and/or chest x-ray were evaluated. Patients were evaluated for infection after lumbar fusion. Results: We found 222 patients (76.3%) had a postoperative temperature of 37.7 ℃, and 162 patients (55.7%) had a postoperative temperature of 38.3 ℃ or higher. The percentage of febrile patients trended down following the mean 1.8days (from the first postoperative day to seventh postoperative day). Infection rate was 9 patients (3.1%), respiratory virus (1.7%), urinary tract infection (0.3%), phlebitis (0.3%), and surgical site infection (1.4%). There was no correlation between Tmax > 37.7℃ or Tmax > 38.3℃, and timing of fever, positive blood or urine cultures, pneumonia, or surgical site infection. Risk factors for increased postoperative fever following surgery were confirmed to be delay of defecation (OR=1.37, p=.046), and shorten of remove drainage (OR=0.66, p=.037). Conclusions: The incidence of fever was 76.3% after lumbar fusion and the drainage time was faster in the case of fever. It was thought that the bleeding was absorbed at the operation site and fever occurred. The prevalence of febrile septicemia was higher in patients with long bowel movements before surgery than after surgery. Clinical symptoms should be considered because postoperative fever cannot be determined by fever alone because fever and infection are not significant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lumbar%20surgery" title="lumbar surgery">lumbar surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=fever" title=" fever"> fever</a>, <a href="https://publications.waset.org/abstracts/search?q=postoperative" title=" postoperative"> postoperative</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factor" title=" risk factor"> risk factor</a> </p> <a href="https://publications.waset.org/abstracts/76549/risk-factors-for-postoperative-fever-in-patients-undergoing-lumbar-fusion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76549.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">249</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">799</span> Advanced Techniques in Robotic Mitral Valve Repair</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abraham%20J.%20Rizkalla">Abraham J.

Yan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: Durable mitral valve repair is preferred to a replacement, avoiding the need for anticoagulation or re-intervention, with a reduced risk of endocarditis. Robotic mitral repair has been gaining favour globally as a safe, effective, and reproducible method of minimally invasive valve repair. In this work, we showcase the use of the Davinci© Xi robotic platform to perform several advanced techniques, working synergistically to achieve successful mitral repair in advanced mitral disease. Techniques: We present the case of a Barlow type mitral valve disease with a tall and redundant posterior leaflet resulting in severe mitral regurgitation and systolic anterior motion. Firstly, quadrangular resection of P2 is performed to remove the excess and redundant leaflet. Secondly, a sliding leaflet plasty of P1 and P3 is used to reconstruct the posterior leaflet. To anchor the newly formed posterior leaflet to the papillary muscle, CV-4 Goretex neochordae are fashioned using the innovative string, ruler, and bulldog technique. Finally, mitral valve annuloplasty and closure of a patent foramen ovale complete the repair. Results: There was no significant residual mitral regurgitation and complete resolution of the systolic anterior motion of the mitral valve on post operative transoesophageal echocardiography. Conclusion: This work highlights the robotic approach to complex repair techniques for advanced mitral valve disease. Familiarity with resection and sliding plasty, neochord implantation, and annuloplasty allows the modern cardiac surgeon to achieve a minimally-invasive and durable mitral valve repair when faced with complex mitral valve pathology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=robotic%20mitral%20valve%20repair" title="robotic mitral
