显微内窥镜治疗脱出型腰椎间盘突出症疗效分析
Analysis of clinical efficacy of microendoscopic discectomy in treating prolapsed lumbar disc herniation

目的:探讨显微内窥镜腰椎间盘切除术(MED)治疗脱出型腰椎间盘突出症的临床疗效。方法:选择2015年9 月至2016年9月应用MED(观察组,70例)和传统椎板切除手术(对照组,60例)治疗的脱出型腰椎间盘突出症患者进行随访,统计并比较两组患者术前、术后1周、1个月、3个月、6个月、9个月、12个月的日本骨科协会评估治疗分数(JOA,评估患者功能障碍)、视觉模拟评分(VAS,评估患者的疼痛强度)、MacNab 疗效评定标准(评估临床疗效的优良率)以及两种患者手术时间、术中出血、并发症和术后住院时间的差异。结果:所有患者术后JOA评分较术前明显升高,术后VAS评分较术前明显降低; MED的手术时间、术中出血量、术后住院时间均优于传统椎板切除术(P<0.05)。结论:MED是治疗脱出型腰椎间盘突出症的有效方法。
Aim: To explore the clinical efficacy of microendoscopic discectomy(MED)in treating prolapsed lumbar disc herniation(LDH).Methods: Seventy patients with prominent LDH undergoing MED(observation group)and 60 patients with the same symptom undergoing traditional laminectomy(control group)from September 2015 to September 2016 were selected for follow-up. For the two groups, the related results of JOA scores(for evaluating dysfunction), VAS scores(for evaluation pain intensity), MacNab effect(for evaluating acceptance rate of efficacy), operation time, bleeding amount, complication, and postoperation hospital stay at pre-operation, 1 week, 1 month, 3 months, 6 months, 9 months and 12 months after operation were compared.Results: For all the 130 patients, the JOA scores were higher than pre-operation; the postoperative VAS scores were lower than pre-operation; MED was better than traditional laminectomy in operative time, intraoperative blood loss, and postoperative hospital stays(P<0.05).Conclusion: MED is effective for curing LDH
