【摘要】 目的:回顾性分析内窥镜下椎间盘切除术(MED)治疗腰椎间盘突出症术后复发的发生率及影响因素。方法:2009年1月~2014年1月年经MED治疗的单节段腰椎间盘突出症患者共322例,男203例,女119例;年龄39±12岁(14~84岁);随访28.6±17.8个月(12~68个月)。应用日本骨科协会腰椎功能评分(腰椎JOA评分)评价治疗效果。采用卡方检验分别分析MED术后复发与年龄、性别、职业、体重指数、节段、突出类型、突出部位、术后活动程度等因素的关系。通过Logistic回归对MED术后复发的相关因素进行多因素分析。结果:术后21例患者复发,复发率为6.5%,其中19例为同部位复发,2例为对侧部位复发。复发时间为术后13.6±17.8个月(1~60个月),其中16例(76.2%)为MED术后1年内复发。单因素卡方分析显示突出类型及术后活动程度与MED术后复发有关,而与性别、年龄、职业、体重指数、节段、突出部位无显著相关性;多因素Logistic回归分析显示突出类型(P=0.009,OR=2.762,CI=1.282~5.942)、术后活动程度(P=0.026,OR=1.907,CI=1.079~3.370)与术后复发显著性相关。结论:脱出型、游离型及高强度术后活动程度为MED术后复发的危险因素。 |

【Abstract】 Objectives: To investigate the recurrence rate after microendoscopic discectomy(MED) for lumbar disc heniation(LDH) retrospectively, and to explore the influential factors related to recurrence. Methods: From January 2009 to January 2014, 322 patients with single-level LDH who underwent MED were enrolled in this study. There were 203 males and 119 females(age range, 14-84 years; mean age, 39±12 years; follow-up range, 12-68 months; mean follow-up, 28.6±17.8 months). The clinical curative effect was evaluated by using lumbar JOA score system. The influential factors were investigated including age, gender, occupation, body-mass index(BMI), postoperative activity level, and level, type, site of LDH. The relationships between the variables and recurrent LDH were evaluated by single factor chi-squared and multiple logistic regression analysis. Results: Recurrent LDH was observed in 21 patients(6.5%). There were 19 cases at the same level in the ipsilateral side as the original LDH, and 2 cases in the contralateral side. The mean time interval between MED and recurrence was 13.6±17.8 months(range, 1-60 months). There were 16(76.2%) recurrent patients within 1 year after MED. Single factor chi-squared analysis revealed herniation type and postoperative activity level significantly related with recurrent LDH, which had no significant correlation with other factors including age, gender, occupation, body-mass index(BMI), level and site of LDH. Multivariate analysis showed that herniation type and postoperative activity level were risk factors for recurrent LDH(P=0.009, OR=2.762, CI=1.282-5.942; P=0.026, OR=1.907, CI=1.079-3.370, respectively). Conclusions: Our study suggests that extrusion, sequestration and high-intensity of postoperative activity level may significantly increase the incidence of recurrent LDH. |
