Objective To evaluate the influence of preserving left colonic artery on postoperative anastomotic leakage and short-term effect in patients with laparoscopic radical resection of middle and low rectal cancer.
Methods A total of 90 patients with laparoscopic radical resection of middle and low rectal cancer were selected as research objects. A total of 45 patients in the observation group chose to preserve left colonic artery, while 45 patients in control group decided not to preserve the left colonic artery, and the intraoperative and postoperative clinical indexes were compared between the two groups.
Results Patients in both groups successfully completed laparoscopic surgery. There were no significant differences in operation time, intraoperative blood loss, incidence rate of anastomotic leakage, number of lymph node dissection, postoperative hospital stay, postoperative anal exhaust time and spontaneous urination time between the two groups (P>0.05). There were significant differences in free spleen curvature, terminal ileostomy rate and postoperative incidence of low anterior resection syndrome between the two groups (P < 0.05).
Conclusion Preserving the left colonic artery can effectively ensure the blood supply of the intestinal canal at the proximal end of the anastomosis, alleviate the injury of inferior plexus of upper abdomen, and reduce the incidence of postoperative complications.
