[A meta-analysis on the outcomes and potential benefits of hybrid robotic technique in rectal cancer surgery].

摘要

OBJECTIVE: 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.
