显微内镜治疗腰椎间盘突出症

A Study on microendoscopic discectomy system in the treatment to lumbar disc herniation

目的 探讨第二代椎间盘镜手术系统治疗腰椎间盘突出症的效果。 方法 2 0 0 0年 5月至 2 0 0 1年 10月采用显微内镜髓核摘除术共治疗 85例、98个间隙腰椎间盘突出症 ,单间隙突出者 72例 ,双间隙突出者 13例 ,合并侧隐窝狭窄者 15例。 结果 所有病例均获得 (6～ 2 0 )个月随访 ,平均 14个月。优良率 92 9% (79 85 )。随访期间无患者出现腰椎不稳。患者术后第 3天即可下床活动 ,切口仅长 1 6cm ,行皮内缝合 ,不需拆线。本组患者均在术后 (3～ 5 )天出院。 结论 显微内镜治疗腰椎间盘突出症近期疗效满意 ,选择合适的病例和仔细的操作是手术成功的关键。

Objective To evaluate the second generation micro-endoscopic discectomy (MED) system in the treatment of lumbar disc herniation. Methods Eighty-five patients with single or double level lumbar disc herniation were treated with MED under epidural anesthesia from May 2000 to October 2001.Single disc herniation was in 72 cases, double disc herniation in 13 cases; lateral recess stenosis in 15 cases. Results The average following-up period was 14 months and the successful therapeutic results achieved 92 9%(79/85). the patients were allowed to walk 3 d and discharged 3～5 d after operation. The length of incision was only 1.6 cm. Conclusions MED has short-term satisfactory therapeutic efficacy in the treatment of lumbar disc herniation. The suitable indication and precise technique are the key for the operation.
