However, few reports have described the results of endoscopic posterior decompression (EPD) with laminectomy performed under local anesthesia. This study aimed to evaluate the clinical and radiological outcomes of EPD performed under local anesthesia in patients with LSS and to compare the procedural outcomes in patients with and without preoperative spondylolisthesis.<\/jats:p><\/jats:sec>METHODS<\/jats:title>Fifty patients (28 female and 22 male) who underwent EPD under local anesthesia were included in this study. Patients were assessed before surgery and were followed up with regular outpatient visits (at 1, 3, 6, 12, and 24 months postoperatively). Clinical outcomes were evaluated using the visual analog scale (VAS), Oswestry Disability Index (ODI), and the 36-Item Short Form Survey (SF-36) outcome questionnaire. Radiological outcomes were assessed by measuring lumbar lordosis, disc-wedging angle, percentage of vertebral slippage, and disc height index on plain standing radiographs.<\/jats:p><\/jats:sec>RESULTS<\/jats:title>The VAS, ODI, and SF-36 scores were significantly improved at 1 month after surgery compared to the baseline mean values, and the improved scores were maintained over the 2-year follow-up period. Radiological progression was found in 2 patients during the follow-up period. Patients with and without preoperative spondylolisthesis had no significant differences in their clinical and radiological outcomes.<\/jats:p><\/jats:sec>CONCLUSIONS<\/jats:title>EPD performed under local anesthesia is effective for LSS treatment. Similar favorable outcomes can be obtained in patients with and without preoperative spondylolisthesis using this approach.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2018.5.spine171337","type":"journal-article","created":{"date-parts":[[2018,9,28]],"date-time":"2018-09-28T14:02:23Z","timestamp":1538143343000},"page":"661-666","source":"Crossref","is-referenced-by-count":28,"title":["Endoscopic posterior decompression under local anesthesia for degenerative lumbar spinal stenosis"],"prefix":"10.3171","volume":"29","author":[{"given":"Myung Soo","family":"Youn","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Myungeun Hospital;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jong Ki","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Biomedical Research Institute, Pusan National University School of Medicine, Busan; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tae Sik","family":"Goh","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Biomedical Research Institute, Pusan National University School of Medicine, Busan; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung Min","family":"Son","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Pusan National University Yangsan Hospital, Pusan National University School of Medicine, Yangsan, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jung Sub","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Biomedical Research Institute, Pusan National University School of Medicine, Busan; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Neurosurg Spine","doi-asserted-by":"publisher","first-page":"339","DOI":"10.3171\/2014.11.SPINE13597","article-title":"Minimally invasive laminectomy for lumbar spinal stenosis in patients with and without preoperative spondylolisthesis: clinical outcome and reoperation rates","volume":"22","author":"Alimi M","year":"2015","unstructured":"Alimi M, Hofstetter CP, Pyo SY, Paulo D, H\u00e4rtl R: Minimally invasive laminectomy for lumbar spinal stenosis in patients with and without preoperative spondylolisthesis: clinical outcome and reoperation rates.
