BACKGROUND:No data for patients with failed back surgery syndrome (FBSS) based on the location of adhesions separated by epiduroscopic adhesiolysis have been reported.METHODS:We performed epiduroscopic adhesiolysis on 28 FBSS patients to examine the impact of differences in the locations of the separated regions on the treatment results.We performed fluoroscopic imaging through the sacral hiatus to assess the condition of adhesions in the epidural space during the post-adhesiolysis observation period.RESULTS:In patients in whom only the epidural space was separated by adhesiolysis,there was a significant improvement in the Roland-Morris disability questionnaire (RDQ) score until 12 weeks after adhesiolysis,but the score gradually returned to the preoperative value thereafter.Among patients in whom the nerve root responsible for radicular pain was separated,there was a long-term improvement in the RDQ,Oswestry disability index 2.0 (ODI),and Japanese Orthopedic Association Assessment of Treatment (JOA) scores.Among patients in whom both the epidural space and the nerve root responsible for pain were separated,there was a 12 week improvement in the RDQ score and 24 week improvements in the ODI and JOA scores.CONCLUSIONS:Progressive epidural imaging after adhesiolysis suggested that pain was caused by re-adhesion around the nerve root.Since re-adhesion of the nerve root required some time,the effect of adhesiolysis was maintained for extended periods in these cases.We suggest that epiduroscopic adhesiolysis is an effective therapy for FBSS patients,and that adhesiolysis of the nerve root may exhibit the long-term (24 weeks) efficacy in patients with pain.

背景：腰椎手术失败综合症（FBSS）患者行硬膜外腔镜下粘连松解术,其粘连分离部位的选择对治疗结果的影响尚无相关报道.方法：我们对28例FBSS患者实施了硬膜外腔镜下粘连松解术,经由骶裂孔采用荧光透视成像法评估粘连分解术后观察期内硬膜外腔的粘连情况,观察不同分离区域定位对治疗效果的影响.
结果：行硬膜外腔粘连分离的患者,术后12周内,其罗兰莫里斯残疾问卷（ RDQ ）评分有显著改善,但其后评分逐渐恢复至术前值.对引起神经根性疼痛的神经根进行分离的患者,其 RDQ ,Oswestry功能障碍指数2.0 （ODI） ,和日本骨科协会评估治疗（ JOA ）分数均有长期改善.同时行硬膜外腔粘连分离及神经根分离的患者,术后12周RDQ评分及24周ODI指数与JOA分数均有改善.结论：粘连松解术后渐进式硬膜外腔成像结果提示,术后疼痛的原因是神经根周围的再次粘连.由于神经根的再次粘连需要一段时间,因此以上病例粘连松解术后能保持长时间的效果.我们的结果提示,硬膜外腔粘连松解术对FBSS患者是一种有效的治疗方法,且神经根处的粘连松解对疼痛患者可能会有长期（ 24周）的疗效.
