目的 比较微创胸腔镜手术与传统开胸手术治疗纵膈肿瘤的临床疗效. 方法 将86例纵膈肿瘤患者按照手术方式分为观察组(n=44)与对照组(n=42),观察组患者实行微创胸腔镜手术,对照组患者实行传统开胸手术,比较两组手术时间、切口长度、术后引流量、术后住院时间,比较两组的临床疗效及并发症发生情况.结果 研究组手术时间、切口长度、术后引流量、住院时间均显著少于对照组(P<0.01).观察组总有效率为93.2%,对照组为76.2%,观察组显著高于对照组(P<0.05).观察组并发症发生率为9.1%,对照组为38.1%,观察组显著低于对照组(P<0.01).结论 微创胸腔镜术治疗纵膈肿瘤效果显著,具有创伤小、耗时短、患者恢复快等特点,且并发症少,优于传统开胸手术,值得临床推广应用.“,”Objective To compare the efficacy between minimally invasive thoracoscopic surgery (MITS) and thoracotomy for mediastinal tumor.Methods Eighty-six patients with mediastinal tumors were assigned to observation (n=44) and control group (n=42) according to operative methods, observation group received MITS and the control did traditional thoracotomy, and such indexes compared between 2 groups as operation times, incision lengths, postoperative drainage volumes and postoperative lengths of stay as well as efficacies and complications.Results Operation times, incision lengths, postoperative drainage volumes and postoperative lengths of stay were significantly fewer in observation than in control group (P<0.01).Total effective rate was significantly higher in observation than in control group (93.2% vs.76.2%, P<0.05).The incidence of complications was significantly lower in observation than in control group (9.1% vs.38.1%, P<0.01).Conclusion The MITS has an evident effect and the characteristics of smaller trauma, shorter time consuming, rapider recovery and fewer complications compared with traditional thoracotomy in the treatment of mediastinal tumor, deserves clinical generalization and application.
