Objective: The objective of this study was to investigate the clinical effect of overlap anastomosis and functional end-to-end anastomosis (FEEA) in laparoscopic radical resection of colorectal cancer (CRC). Methods: The clinical data of 180 patients who underwent laparoscopic radical resection of CRC and side-to-side anastomosis were retrospectively collected; the patients were divided into the Overlap group and FEEA group, according to the anastomosis method that was used to treat them. Results: The Overlap group had a shorter operation time, anastomosis time, post-operative hospital stay, post-operative feeding time, and post-operative exhaust time than the FEEA group (p < 0.05). The total incidence of post-operative complications was 14.4% (13/90) in the FEEA group and 0.7% (6/90) in the Overlap group, and there was no significant difference between the two groups (p > 0.05). Conclusions: Overlapping anastomosis can shorten the operation time and accelerate the recovery of intestinal function without increasing the incidence of post-operative complications, and it will not affect the quality of life and survival of patients in the short term after surgery.
