Laparoscopic complete mesocolic excision in colon cancer: a prospective cohort study

Abstract

Introduction: Compared to conventional colon cancer surgery, laparoscopic complete mesocolic excision (CME) increases the likelihood of lymph node dissection. However, this surgery is not yet considered a safe strategy. The authors study this topic to evaluate the safety and feasibility of this surgery. Methods: A prospective cohort study was performed on patients undergoing laparoscopic CME surgery at the Hue University of Medicine and Pharmacy Hospital and Hue Central Hospital. Results: Demographic data, surgical features, and postoperative complications. Evaluate different clinicopathological factors determining the number and distribution of lymph nodes; and the rate of lymph node metastasis by tumor location and lymph node groups. Three-year overall survival and disease-free survival follow-up after surgery. Conclusion: The results of laparoscopic CME colectomy surgery are safe, with a reliable maximum number of harvested nodes.
