Abstract:
Objective To compare the efficacies of da Vinci robotic and traditional laparoscopic resection for colorectal cancer.Methods Databases including Pubmed,Cochrane Library,EMBASE,Medline,Wanfang,CNKI,VIP and FMJS were searched,and literatures published before February 2012 were retrieved.Randomized controlled trials (RCTs) and non-randomized controlled trials (NRCTs) focusing the comparison between da Vinci robotic and laparoscopic resection for colorectal cancer were collected.All the literatures retrieved were screened according to preset standards,and the patients were divided into robotic group and laparoscopic group.A meta analysis on the effectiveness of robotic and laparoscopic surgery for colorectal cancer was carried out using the RevMan 5.1 software.Categorical variables were presented by odds ratio (OR) and 95％ confidence interval (95 ％ CI),continuous variables were presented by weighted mean difference (WMD) and 95 ％ CI.Results One RCT and 10 NRCTs including 974 patients with colorectal cancer were screened out and there were 426 patients in the robotic group and 548 patients in the laparoscopic group.Compared with conventional laparoscopic surgery,longer operation time,lower rate of conversion to laparotomy and shorter anal exsufflation time were observed in the robotic group (WMD =25.61,OR =0.32,WMD =-0.21,P ＜ 0.05).There were no significant differences in the operative blood loss,number of lymph node dissected,distal resection margin,morbidity and duration of hospital stay between the robotic group and the laparoscopic group (WMD =-23.14,-0.31,0.14,OR =1.06,WMD =-0.43,P ＞ 0.05).Conclusion The efficacies of da Vinci robotic and laparoscopic surgery for the treatment of colorectal cancer are comparable,while da Vinci robotic surgery has the features of lower rate of conversion to laparotomy and shorter anal exsufflation time.
