椎间盘镜手术与小切口手术治疗腰椎间盘突出症的比较研究

目的比较椎间盘镜髓核摘除术（MED）与小切口髓核摘除术（MTD）治疗腰椎间盘突出症的远期临床疗效及优缺点。方法随机选取本院2004—01—2007—01期间收治的腰椎间盘突出症患者98例，采用MED手术55例，MTD手术43例，将其手术疗效、腰椎功能改善率及具体手术情况进行统计学分析。结果平均随访时间76个月（72～81个月），两组患者的治疗优良率、腰椎功能改善率及手术时间均无统计学差异（P〈0．05），但MED组在手术出血量、住院时间、手术切口长度方面均低于MTD组（P〈0．05）。结论MED与MTD治疗腰椎间盘突出症的远期临床疗效相当．各有优缺点，二者可根据临床的具体情况选用。

Comparison of the clinical efficacy of microendoscopic discectomy and microtraumatic discec- tomy in treating lumbar disc herniation

Objective To compare the long term clinical efficacy of microendoscopic discectomy （MED） and microtraumatic discectomy （MTD） in the treatment of lumbar disc herniation （LDH）, as well as their merits and drawbacks. Methods 98 patients with LDH in our hospital from Jan- uary 2004 to January 2007 were randomly selected. 55 cases were treated by MED,and the other 43 cases received MTD treatment. The clinical efficacy,lumbar function improvement rate and oper- ative outcomes of the two groups were statistically analyzed. Results There were no significant dif- ferences in the excellent rate of the surgical treatment,lumbar function improvement rate and opera- tion time between the two groups （P〉0.05）. The blood loss,length of hospital stay and incision length of the MED group were significantly lower than those of MTD group （P〈0.05）. Conclusion Both MED and MTD can be selected according to the specific clinical situations, in respect that MED and MTD have similar long term clinical efficacy in treatment of LDH,and have their own merits and drawbacks.
