摘要目的：系统评价混合式机器人手术在直肠癌根治术中的应用效果以及相对于腹腔镜手术的潜在优势。方法检索2007年1月至2013年12月Medline（PubMed）、Cochrane、EMBASE、OVID、中国期刊全文数据库（CNKI）、万方数据库和手工检索发表的资料和会议论文并追索纳入文献的参考文献，查找国内外关于混合式机器人手术与腹腔镜手术在治疗直肠癌中应用比较的相关文献，采用RevMan 5．2软件进行Meta分析。结果经过文献质量评估，筛选出7篇文献，共计884例患者，其中混合式机器人手术者430例，腹腔镜手术者454例。相对于传统腹腔镜手术，混合式机器人直肠癌根治术的手术中转率、术中出血量明显下降，但手术时间延长。术中获取淋巴结数目和术后患者排气时间、住院天数以及术后并发症发生率两者差异无统计学意义（均P＞0．05）。结论与腹腔镜手术相比，混合式机器人手术具有手术中转率低和出血量少的潜在优势。但目前支持机器人手术推广应用的证据依然有限。

abstractsObjective To assess the efficacy and potential benefits of hybrid robotic technique in rectal cancer surgery. Methods A meta-analysis on the literatures about the hybrid robotic proctectomy from Medline (PubMed), Cochrane, EMBASE, OVID, CNKI, Wanfang database, manually retrieved articles between January 2007 and January 2013 was performed by RevMan 5.2. Results According to Newcastle-Ottawa Scale, 7 articles were screened. A total of 884 cases (430 robotic cases and 454 laparoscopic cases) were included. Compared to the laparoscopic group, the conversion rate and intraoperative blood loss was reduced and operation time was longer in the robotic group. The number of lymph node harvested, time to first flatus, length of hospital stay and postoperative complication morbidity were not significantly different between the two groups. Conclusion Potential benefits of robotic surgery include lower conversion rate and less blood loss , however, present evidence supporting the robotic benefits is still limited.
