Indications for surgery were single- or double-level LSS, persistent neurological symptoms, and failure of conservative treatment. Microendoscopy provided wide visualization through oblique lenses and allowed bilateral decompression via a unilateral approach, through partial resection of the base of the spinous process, thereby preserving the supraspinous and interspinous ligaments and contralateral musculature. Clinical symptoms and signs of low-back pain were evaluated prior to and following surgical intervention by applying the Japanese Orthopaedic Association (JOA) scoring system, Roland-Morris Disability Questionnaire (RMDQ), Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ), and 36-Item Short Form Health Survey (SF-36). These items were evaluated preoperatively and 2 years postoperatively.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>Effective circumferential decompression was achieved in all patients. The 2-year follow-up evaluation was completed for 310 patients (148 men and 162 women; mean age 68.7 years). The average recovery rate based on the JOA score was 61.3%. The overall results were excellent in 34.9% of the patients, good in 34.9%, fair in 21.7%, and poor in 8.5%. The mean RMDQ score significantly improved from 11.3 to 4.8 (p &lt; 0.001). In all categories of both JOABPEQ and SF-36, scores at 2 years' follow-up were significantly higher than those obtained before surgery (p &lt; 0.001). Twelve surgery-related complications were identified: dural tear (6 cases [1.9%]), wrong-level operation (1 [0.3%]), transient neuralgia (4 [1.3%]), and infection (1 [0.3%]). All patients recovered, and there were no serious postoperative complications.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Microendoscopic laminotomy is a safe and very effective minimally invasive surgical technique for the treatment of degenerative LSS.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2013.8.spine13125","type":"journal-article","created":{"date-parts":[[2013,10,4]],"date-time":"2013-10-04T14:05:57Z","timestamp":1380895557000},"page":"664-671","source":"Crossref","is-referenced-by-count":65,"title":["Endoscope-assisted spinal decompression surgery for lumbar spinal stenosis"],"prefix":"10.3171","volume":"19","author":[{"given":"Akihito","family":"Minamide","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Munehito","family":"Yoshida","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Yamada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yukihiro","family":"Nakagawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaki","family":"Kawai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuhiro","family":"Maio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Hashizume","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Iwasaki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shunji","family":"Tsutsui","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-spine13125","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"1142","DOI":"10.1097\/00007632-199011010-00011","article-title":"Biomechanical evaluation of lumbar spinal stability after graded facetectomies","volume":"15","author":"Abumi","year":"1990"},{"key":"b2-spine13125","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"1424","DOI":"10.1097\/00007632-200006010-00016","article-title":"Lumbar spinal stenosis: conservative or surgical management?: a prospective 10-year study","volume":"25","author":"Amundsen","year":"2000"},{"key":"b3-spine13125","series-title":"Clin Orthop Relat Res","doi-asserted-by":"publisher","first-page":"90","DOI":"10.1097\/BLO.0b013e31803799a9","article-title":"Is spinal stenosis better treated surgically or nonsurgically?","volume":"458","author":"Athiviraham","year":"2007"},{"key":"b4-spine13125","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"556","DOI":"10.1097\/00007632-200003010-00005","article-title":"Surgical and nonsurgical management of lumbar spinal stenosis: four-year outcomes from the Maine Lumbar Spine Study","volume":"25","author":"Atlas","year":"2000"},{"key":"b5-spine13125","series-title":"J Spinal Disord","doi-asserted-by":"publisher","first-page":"461","DOI":"10.1097\/00002517-199306060-00001","article-title":"The role of fusion and instrumentation in the treatment of degenerative spondylolisthesis with spinal stenosis","volume":"6","author":"Bridwell","year":"1993"},{"key":"b6-spine13125","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"2807","DOI":"10.1097\/00007632-199712150-00003","article-title":"1997 Volvo Award winner in clinical studies.
