Popis: Objective To compare the postoperative complications of intracorporeal anastomosis (ICA) and extracorporeal anastomosis (ECA) in patients undergoing laparoscopic right colectomy (LRC). Background Although several studies have compared postoperative complications of ICA and ECA after LRC, most were retrospective studies. Methods We performed a comprehensive electronic search of the literature to identify studies that compared postoperative complications between ICA and ECA in patients who underwent LRC. We performed meta-analysis using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI) of experiencing complications, and we analyzed heterogeneity using I2 statistics. Results Fifteen studies consist of randomized controlled trials, case-control studies, and propensity score matching studies involving a total of 3219 patients who underwent LRC were included. Among 1377 patients who received ICA, 255 (18.5%) had postoperative complications, whereas among 1652 patients who received ECA, 373 (22.6%) had such complications. The results of the meta-analysis revealed that ICA was associated with a significantly reduced risk of postoperative complications (RR, .73; 95% CI: .57-.95; P = .02; I2 = 57%) compared with ECA. Although there was no significant difference between the 2 groups in risk of anastomotic leakage (RR, .67; 95% CI: .39-1.17; P = .16; I2 = 8%), there was a significant difference between them in risk of surgical site infection (RR, .50; 95% CI: .34-.71; P = .0002; I2 = 0%). Conclusions Intracorporeal anastomosis is associated with a reduced risk of postoperative complications compared with ECA in patients undergoing LRC.
