结直肠癌腹腔镜手术对比开放手术远期疗效与安全性的荟萃分析

目的荟萃分析比较腹腔镜手术与开放手术治疗结直肠癌的远期疗效和安全性。方法检索1991年1月～2007年7月发表的腹腔镜手术对比开放手术治疗结直肠癌的随机对照试验,摘录入选文献数据,采用RevMan4.2软件进行统计分析。结果按照筛选标准,共有14篇文献4989例结直肠癌患者入选。并发症两组除肠粘连发生率有差异外（P=0.002）,其他并发症的差异均无显著性。远期疗效如3年生存率、5年生存率、局部复发和远处转移两组差异无显著性。结论腹腔镜手术治疗结直肠癌创伤小,安全有效,远期疗效与开放手术无差异。

Long-term Survival and Safety of Laparoscopy and Open Surgery for Colorectal Cancer: Meta-analysis

Objective To compare the long-term survival rate and safety of laparoscopic surgery(LS)with those of open surgery(OS)in the treatment of colorectal cancer by using Meta-analysis.Methods Randomized controlled trails reported between January 1991 and July 2007 comparing the outcomes of LS and OS in patients with colorectal cancer were collected and analyzed by using RevMan4.2.Results Totally,14 reports involving 4989 colorectal cancer patients were enrolled in this study.Significant difference was found in the morbidity rate of bowel adhesion between the two groups(P=0.002).The long-term outcomes,including the 3-and 5-year survival rates,and the rates of local recurrence and distant metastasis,were not significantly different between the two groups.Conclusions Laparoscopic surgery is effective and safe for colorectal cancer with a similar long-term survival rate as that of the open surgery.
