Introduction: Whether the incidence rate of deep venous thrombosis (DVT) between laparoscopic and open colorectal cancer surgery the same or not were under the debated without conclusion. The aim of this study was to compare the incidence of DVT after laparoscopic or open colorectal cancer surgery by meta-analysis. Materials and Methods: The open published articles comparing the incidence of DVT after laparoscopic or open colorectal cancer were collected in the data bases of Medline, the Cochrane central register of controlled trials and CNKI. The relative risk (RR) was pooled by using random or fixed effect mode to evaluate the incidence of DVT between laparoscopic or open colorectal cancer surgery.Results: After searching the databases, 9 randomized clinical studies with 2606 colorectal cancer cases were included in this meta-analysis. The mean operation time was 201.8 ± 17.28 min with its range of 180.0-224.4 min in the laparoscopic surgery group and 148.1 ± 18.8 min with its range of 135.0-184.0 min in the open surgery group. The operation time for laparoscopic surgery group were significant lower than in the open surgery group (P < 0.05). The RR of DVT between the laparoscopy and open surgery groups was 0.71 with its 95% confidence interval of 0.35-1.45 (P = 0.35). Conclusions: The operation time in laparoscopic colorectal cancer surgery was statistical longer than in the open colorectal cancer surgery, but the DVT risk of the two surgery approach was not different according to this meta-analysis.
