后路椎间盘镜与开放椎板开窗治疗腰椎间盘突出症的比较研究

A Comparative Study on Microendoscopic Discectomy and Open Discectomy for Lumbar Dischermiation

目的:比较后路椎间盘镜髓核摘除术(microendoscopicdiscectomy,MED)与开放椎板开窗(open discecto-my,OD)治疗腰椎间盘突出症的临床效果及优缺点。方法:回顾性分析2006年7月至2007年7月手术治疗48例腰椎间盘突出症(椎间盘镜组、开放椎板开窗组各24例),分别比较两组手术时间、术中出血量、术后卧床时间、术后住院时间;术后随访按Nakai评分统计术后优良率。结果:椎间盘镜组和开放椎板开窗组术后优良率差异无统计学意义,两组在术中出血量、术后卧床时间、术后住院时间差异有统计学意义,椎间盘镜组优于开放手术组。结论:椎间盘镜与开放椎板开窗术均能缓解腰椎间盘突出症症状,但椎间盘镜具有切口小、组织损伤轻、恢复较快的优点。

Objective： To compare the clinical therapeutic effects as well as advantages and disadvantages of microendoscopic discectomy （MED）and open discectomy（OD）. Methods： A restrospective study was carried out in a series of 48 patients（24 treated by MED and 24 by OD ）treated from July 2006 to July 2007. The operation time ,bleeding during the operation, postoperative stay and duration of hospitalization after operation were compared. The rate of excellent and good outcomes were evaluated according to Nakai criterian. Results： Significant difference was found between MED group and OD group in the operation time, bleeding ,postoperative stay and duration of hospitalization after operation. Conclusion： Compared with the OD, MED has advantages such as smaller incision, mild damage of tissues, bleeding less, quicker recovery. By both methods, the clinical outcomes are similar in the treatment to relieve the symptoms of the lumbar dischemiation.
