全脊柱内镜下治疗极外侧型腰椎间盘突出症的疗效评价

摘要

Objective To evaluate the clinical efficacy of percutaneous endoscopic lumbar discectomy (PELD) on treatment of far lateral lumbar disc herniation (FLDH). Methods We retrospectively analyzed 27 patients with FLDH underwent percutaneous endoscopic lumbar discectomy from June 2014 to September 2015, age from 41 to 64, average 52.3. The average operation time, intraoperative blood loss and length of hospital stay were collected. The lumbocrural pain perception of patients before and after surgery was assessed by visual analog scale (VAS) and postoperative lumbar functional recovery after surgery by modified MacNab criteria. Results Average operation time was 69 min (58~109 min), intraoperative blood loss was 18 ml (11~40 ml), and length of stay was 5.0 d (3.0 ~ 10.0 d). VAS score from (8.12 ± 1.25) preoperatively improved to (2.80 ± 1.12) at the 3rd d after operation, (1.59 ± 1.06) at 3 months after operation, and (1.31 ± 0.89) at the last follow-up after operation; There was a statistical difference between preoperative scores and postoperative scores (P < 0.05). Modified MacNab criteria was a ratio of 88.9%. Conclusions PELD on the treatment of far lateral lumbar disc herniation have small area of trauma, faster postoperative recovering and several other advantages,which is a safe and effective minimally invasive surgery.%目的 评估经皮全脊柱内镜下腰椎间盘切除术(PELD)治疗极外侧型腰椎间盘突出症(FLDH)的临床疗效.方法 回顾性分析2014年6月-2015年9月该科采用经皮全脊柱内镜技术治疗FLDH 27例,年龄41~64岁,平均52.3岁,通过观察手术时间、术中出血量和住院时间,采用视觉模拟评分(VAS)评估术前及术后患者腰腿痛情况,改良MacNab评分评估患者腰部功能恢复情况.结果 单节手术时间为69 min(58~109 min)、术中出血量为18 ml(11~40 ml)、住院时间为5.0 d(3.0~10.0 d),术前VAS评分(8.12±1.25),术后第3天VAS评分(2.80±1.12),术后3个月VAS评分(1.59±1.06),末次随访VAS评分(1.31±0.89),术后VAS评分与术前相比差异均有统计学意义(P<0.05).采用改良MacNab标准评估,优良率为88.9%.结论 PELD治疗FLDH具有创伤小、恢复快等优点,是一种安全、有效的微创手术.
