经皮椎间孔内窥镜下手术治疗腰椎间盘突出症的近期疗效观察

目的:评价经皮椎间孔内窥镜下椎间盘切除术治疗腰椎间盘突出症的近期临床效果。方法:2009年9月～2010年3月应用经皮椎间孔内窥镜下椎间盘切除术治疗30例腰椎间盘突出症患者,男19例,女11例,年龄18～60岁,平均40.8岁;病程3个月～4年,平均9个月。术前患者均表现为腰痛伴单侧下肢放射性疼痛,均为单间隙突出,侧方型突出25例,旁中央型突出5例。均采用局部麻醉下手术。术前、术后不同时间对患者腰、腿痛进行VAS评分;采用Oswestry功能障碍指数(ODI)评估腰椎功能改善情况;术后6个月随访时采用Mac-Nab标准评价疗效。结果:30例患者均成功实施手术,手术时间55～135min,平均75min,术中出血5～30ml,平均12ml。术后第二天戴腰围下地行走。1例术后患侧膝反射减弱;1例术后腰痛缓解,出院后腿痛加重,均经保守治疗后恢复正常或症状缓解。随访6～12个月,平均9.2个月。腰痛、腿痛VAS由术前的平均6.5分、8.7分下降到术后6个月时的1.9分、1.5分,与术前比较均有显著性差异﹙P<0.01﹚。ODI由术前平均77.38%下降至术后6个月时的平均19.09%。根据MacNab标准,术后6个月时随访优10例(33.3%),良16例(53.3%),可3例(10%),差1例(3.3%),优良率86.6%。结论:经皮椎间孔内窥镜下椎间盘切除术治疗腰椎间盘突出症创伤小,并发症少,术后恢复快,近期疗效较满意。
