  "abstract": "INTRODUCTION:: Right-sided colon cancer (CC) represents a substantial proportion of colorectal malignancies, and laparoscopic right hemicolectomy has become the established surgical standard of care. However, consensus on the optimal anastomotic configuration—end-to-side vs functional end-to-end—remains lacking in current clinical practice.\n\nAIM:: This study aimed to compare end-to-side anastomosis (ESA) with functional end-to-end anastomosis (FEEA) in laparoscopic right hemicolectomy for CC involving extracorporeal anastomosis, thereby providing evidence-based guidance for selecting the optimal anastomotic technique.\n\nMATERIALS AND METHODS:: We systematically searched PubMed, Web of Science, the Cochrane Library, and Embase for studies comparing ESA with FEEA in laparoscopic right hemicolectomy for CC involving extracorporeal anastomosis. The search included publications up to January 2026 with no language restrictions. Eligible studies were selected based on the population, intervention, comparison, outcome, and study design framework.\n\nRESULTS:: A total of 5 studies were included in the analysis. ESA was associated with a reduced incidence of ileus, as compared with FEEA (P <0.001). No significant differences were observed between ESA and FEEA in length of hospital stay, time to first flatus, overall postoperative complications, anastomotic leakage, postoperative bleeding, or surgical site infection.\n\nCONCLUSIONS:: In laparoscopic right hemicolectomy for CC involving extracorporeal anastomosis, ESA is associated with a lower incidence of ileus than FEEA.",
