肥胖对腰椎后路手术疗效的影响

Effect of Obesity on Outcome of Posterior Lumbar Surgery

目的分析肥胖是否会对腰椎后路融合手术的并发症发生率及术后疗效造成影响。方法回顾性分析2010年1月至2012年12月,因腰椎退行性疾病而采用单节段腰椎后路减压椎间植骨融合内固定手术治疗的155例患者,根据体质指数(BMI)的值分为肥胖组(35例)与正常组(120例),比较不同体质量患者手术时间、术中出血量及术后并发症情况,同时以调查问卷形式评估手术疗效。结果肥胖组,手术时间明显长于正常组;伤口并发症的发生率高;术后疗效无明显差异。结论肥胖会增加腰椎后路融合手术的难度,并增加伤口并发症风险,并不影响术后疗效。

Objective To analyze whether morbid obesity can affect the incidence of complications and the outcome of surgery in patients undergoing posterior lumbar interbody fusion. Methods Data of155 patients who underwent posterior decompression with single segmental lumbar interbody fusion between January 2010 and December 2012 were analyzed retrospectively. These patients were divided into obesity group and normal group according to the body mass index. The operation time,intraoperative blood loss and complications were compared between the two groups. In addition, the curative efficacies were evaluated using the questionnaire. Results Compared with the normal group,operation time and incidence of complications significantly increased in the 35 obesity patients. There was no significant difference in the curative efficacy between the two groups. Conclusion Morbid obesity can increase the difficulty of posterior lumbar interbody fusion and the risk of wound complications, but cannot affect the clinical outcome.
