Background: The safety of robotic-assisted surgery (RAS) remains a concern. This study aimed to compare the complications after RAS versus laparoscopic-assisted surgery (LAS) for rectal cancer using the Clavien-Dindo classification and to identify risk factors related to the complications. Method: Between March 2010 and June 2016, 556 rectal cancer patients who underwent successful RAS and 1029 patients who received LAS were enrolled in this study. The complications were graded according to the Clavien-Dindo classification, and the possible risk factors related to the complications were analyzed. Results: The overall postoperative complication rate was 14.9%, with a 5% rate of severe complications that were classified as grade III or above in RAS group compared with 17.1% and 4.4% in LAS group. However, no significant difference was found (P = 0.608). A high ASA score was identified as an independent risk factor for overall and severe complications in both groups. The use of more than 3 staples in each operation and the anastomotic site of the anal verge at less than 5 cm were independent risk factors for complications. Conclusions: RAS for rectal cancer is technically safe and it does not significantly improve the complication rate. The incidence of overall complications is still related to tumor location, the general condition of the patients, and the surgical approach.
