Abstract
OBJECTIVE: Robotic and laparoscopic surgery for rectal cancer has been applied in the clinic for decades; nevertheless, which surgical approach has a lower rate of postoperative complications is still inconclusive. Therefore, the aim of this meta-analysis was to compare the postoperative complications within 30 days between robotic and laparoscopic rectal cancer surgery based on randomized controlled trials. METHODS: Randomized controlled trials (until May 2020) that compared robotic and laparoscopic rectal cancer surgery were searched through PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, and China Biology Medicine disc (CBMdisc). Data regarding sample size, clinical and demographic characteristics, and postoperative complications within 30 days, including overall postoperative complications, severe postoperative complications (Clavien-Dindo score ≥ III), anastomotic leakage, surgical site infection, bleeding, ileus, urinary complications, respiratory complications, conversion to open surgery, unscheduled reoperation, perioperative mortality, and pathological outcomes, were extracted. The results were analyzed using RevMan v5.3. RESULTS: Seven randomized controlled trials that included 507 robotic and 516 laparoscopic rectal cancer surgery cases were included. Meta-analysis showed that the overall postoperative complications within 30 days [Z = 1.1, OR = 1.18, 95% CI (0.88-1.57), P = 0.27], severe postoperative complications [Z = 0.22, OR = 1.12, 95% CI (0.41-3.07), P = 0.83], anastomotic leakage [Z = 0.96, OR = 1.27, 95% CI (0.78-2.08), P = 0.34], surgical site infection [Z = 0.18, OR = 1.05, 95% CI (0.61-1.79), P = 0.86], bleeding [Z = 0.19, OR = 0.89, 95% CI (0.27-2.97), P = 0.85], ileus [Z = 1.47, OR = 0.66, 95% CI (0.38-1.15), P = 0.14], urinary complications [Z = 0.66, OR = 1.22, 95% CI (0.67-2.22), P = 0.51], respiratory complications [Z = 0.84, OR = 0.64, 95% CI (0.22-1.82), P = 0.40], conversion to open surgery [Z = 1.73, OR = 0.61, 95% CI (0.35-1.07), P = 0.08], unscheduled reoperation [Z = 0.14, OR = 0.91, 95% CI (0.26-3.20), P = 0.89], perioperative mortality [Z = 0.28, OR = 0.79, 95% CI (0.15-4.12), P = 0.78], and pathological outcomes were similar between robotic and laparoscopic rectal surgery. CONCLUSION: Robotic surgery for rectal cancer was comparable to laparoscopic surgery with respect to postoperative complications within 30 days.
