Purpose: The effect of intracorporeal anastomosis (IA) versus extracorporeal anastomosis (EA) in laparoscopic right hemicolectomy is controversial. The aim of this study was to evaluate the safety, effectiveness, and functional outcomes of IA compared with EA and to explore the timely tendency variations favoring one treatment over another. Materials and Methods: PubMed, EMBASE, and Web of Science were consulted. A systematic review, pairwise meta-analysis, and cumulative meta-analysis were conducted. Results: Twenty-three studies (3755 patients) were included: 45.7% underwent IA, whereas 54.3% underwent EA. The estimated pooled postoperative infectious complications, anastomotic leak, and overall complications risk ratios were 0.51 (95% confidence interval [CI]: 0.31 to 0.84; P = .009), 0.64 (95% CI: 0.40 to 1.03; P = .063), and 0.78 (95% CI: 0.62 to 0.97; P = .028), respectively. The cumulative meta-analysis showed a statistically significant timely tendency in favor of IA while considering infectious and overall complications. The estimated pooled mean difference of time to first flatus, first defecation, first oral diet, and hospital stay were -16.68 (P < .001), -25.94 (P < .001), -16.35 (P < .001), and -0.72 (P < .001), respectively. Again, the cumulative meta-analysis showed a statistically significant timely trend in favor of IA. No differences were found in term of operative time, conversion rate, ileus, bleeding, reoperation, 30-day readmission, and 30-day mortality. Conclusions: Compared with EA, IA seems to be associated with reduced postoperative infectious and overall complications. The time to first flatus, time to defecation, time to liquid diet, and hospital length of stay were estimated to be lower. A statistically significant timely trend favoring IA was noticed for postoperative infectious complications, overall complications, and recovery parameters. Further studies are warranted to confirm these results and to deeply investigate the supposed timely tendency convergence in favor of IA.
