目的 探讨椎板间隙入路经皮脊柱内镜腰椎间盘摘除术(PELD)治疗微小腰椎间盘突出症(MLDH)的临床效果。方法 回顾性分析2019年1月-2020年1月该院收治的12例MLDH患者的临床资料,均使用PELD进行治疗。分析术前1 d和术后不同时间点的视觉模拟评分法(VAS)和Oswestry功能障碍指数(ODI)评分,并且采用MacNab标准对末次随访进行疗效评估。结果 随访时间(12.1±2.6)个月,手术时间(45.5±8.5) min。术后1 d、术后1个月、术后3个月和末次随访时的VAS和ODI评分均较术前明显改善(P <0.05)。Macnab疗效评定:优9例,良3例。结论 椎板间隙入路PELD治疗MLDH,创伤小,症状改善明显,具有较好的临床效果。
Objective To observe the clinical effect of interlaminar approach percutaneous endoscopic lumbar discectomy (PELD) in treatment of minimal lumbar disc herniation (MLDH).Methods Twelve patients with MLDH treated from January 2019 to January 2020 were selected, who were treated by PELD. The visual analogue scale (VAS) and Oswestry disability index (ODI) scores were analyzed at one day before operation and different times after operation, and MacNab rating was used to evaluate the patients at the last follow-up.Results The follow-up time were (12.1 ± 2.6) months. The operation time was (45.5 ± 8.5) min. the VAS and ODI scores at 1 day, 1 month, 3 months after operation and the last follow-up were improved compared with those before operation (P < 0.05). MacNab evaluation showed that 9 cases were excellent and 3 cases were good.Conclusion The treatment of MLDH by interlaminar approach PELD has good clinical effect with little trauma and obvious improvement of symptoms.
