[目的]探讨腰椎间盘镜手术治疗复杂性腰椎管狭窄症患者的疗效.[方法]选取48例复杂性腰椎管狭窄症患者,其中合并脊椎滑脱者26例,合并腰椎骨折者10例,合并脊柱侧凸者12例,均予以后路腰椎间盘镜手术,根据不同情况加用椎弓根器械行矫形、复位、固定及椎间或横突间植骨融合术.综合评估患者手术前后视觉模拟评分(VAS评分)、Oswestry功能障碍指数(ODI)、生活质量[世界卫生组织生存质量简表(WHOQOL-BREF)]评分及相关症状评分的变化.[结果]48例患者术后VAS、ODI及症状评分结果均较术前明显降低(P <0.05),WHOQOL-BREF评分结果均较手术前明显提高,差异均有显著性(P均<0.05).[结论]腰椎间盘镜手术能有效减轻复杂性腰椎管狭窄患者疼痛症状,对改善其功能障碍、提高生活质量等具有积极影响.“,”[Objective]To investigate the efficacy of microendoscopy disectomy in the treatment of patients with complicated lumbar spinal stenosis.[Methods] Forty-eight patients with complicated lumbar spinal ste-nosis were selected as subjects,including 26 patients complicated with spondylolisthesis,10 patients compli-cated with lumbar fractures and 12 patients complicated with scoliosis.All patients were treated with posterior microendoscopy disectomy,and they were treated by orthopaedic treatment,reduction,fixation and interver-tebral or intertransverse fusion with transpedicular instrument according to different conditions.Changes in scores of Visual Analog Scale(VAS score),Oswestry disability index(ODI),quality of life[World Health Organization on Quality of Life Brief Scale(WHOQOL-BREF)]and related symptoms before and after sur-gery were evaluated comprehensively.[Results]Scores of postoperative VAS,ODI and symptoms of 48 cases were significantly lower than those before surgery(P <0.05),while WHOQOL-BREF scores were signifi-cantly higher than those before surgery(P <0.05).[Conclusion]Microendoscopy disectomy can effectively relieve pain symptoms in patients with complicated lumbar spinal stenosis,and it has positive effect on relie-ving functional disability and improving the quality of life.
