Transforaminal endoscopic techniques have become increasingly popular in surgery of patients with lumbar stenosis. The literature has not yet been systematically reviewed. A comprehensive systematic literature review up to November 2009 to assess the effectiveness of transforaminal endoscopic surgery in patients with symptomatic lumbar stenosis was made. Two reviewers independently checked all retrieved titles and abstracts and relevant full text articles for inclusion criteria. Included articles were assessed for quality, and relevant data, including outcomes, were extracted by two reviewers independently. No randomized controlled trials were identified, but seven observational studies. The studies were of poor methodological quality and heterogeneous regarding patient selection, indications, operation techniques, follow-up period and outcome measures. Overall, 69-83% reported the outcome as satisfactory and a complication rate of 0-8.3%. The reported re-operation rate varied from 0 to 20%. At present, there is no valid evidence from randomized controlled trials on the effectiveness of transforaminal endoscopic surgery for lumbar stenosis. Randomized controlled trials comparing transforaminal endoscopic surgery with other surgical techniques are direly needed.
经皮内窥镜下腰椎间孔入路技术在腰椎管狭窄症的治疗中已得到广泛应用，但目前尚无系统评价。本研究旨在对经皮内窥镜下腰椎间孔入路手术治疗腰椎管狭窄症的疗效进行系统评价。检索 2009 年 11 月以前发表的相关文献，按照纳入标准筛选文献、评价质量和提取资料。共纳入 7 项观察性研究，均为低质量研究，在患者选择、适应证、手术技术、随访时间及疗效评价指标等方面存在差异。总体优良率为 69%83%，并发症发生率为 0%8.3%，再手术率为 0%~20%。目前，尚无经皮内窥镜下腰椎间孔入路手术治疗腰椎管狭窄症的高质量随机对照研究，需要开展随机对照试验比较其与其他手术方法的疗效。
