摘要目的：探讨腰椎间盘突出行后路椎间盘镜治疗的临床疗效。方法选择柳江县人民医院2009年7月至2012年11月收治的84例腰椎间盘突出患者为研究对象，随机分为对照组和观察组，每组42例，对照组行传统开放手术治疗，观察组行后路椎间盘镜治疗，比较两组患者的治疗效果。结果观察组术中失血量、术后住院时间均少于对照组（P<0.05）；对照组治疗优良率为73.81%，观察组为92.86%，差异有统计学意义（P<0.05）。结论对腰间盘突出患者实施后路椎间盘镜治疗，效果显著，创伤小，利于患者术后恢复，值得临床进一步推广使用。

abstractsObjective To investigate the clinical effects of posterior approach microendoscopy on lumber spinal stenosis. Methods To select 84 patients with lumber spinal stenosis in people’s hospital of Liujiang from July 2009 to November 2012 as the research objects,and they were randomly divided into control group and observation group,with 42 cases in each group. The control group were treated by the traditional open operations,while the observation group were treated by the posterior approach microendoscopy. Then,the treatment effects of the two groups were analyzed. Results The blood loss volume during operation and the hospital stay after the operation in the observation group were significantly lower than those in the control group(P<0. 05). The fine rate of the control group was 73. 81%,compared with 92. 86%in the observation group,the difference was significant(P<0. 05). Conclusions The treatment of posterior approach mi-croendoscopy on lumber spinal stenosis has evident effect and little trauma,which is good for the recovery after the opera-tion. Thus,it is worth promoting further in the clinical application.
