Safety and feasibility of laparoscopic complete mesocolic excision for right-sided colon cancer: A prospective study

Background: This study aimed to evaluate the early outcomes of laparoscopic complete mesocolic excision (CME) for right colon cancer. Methods: A prospective study was conducted on patients with primary right colon cancer who underwent laparoscopic CME between January 2023 and January 2024 at the Gastrointestinal Surgery Department of the 108 Military Central Hospital. Results: A total of 47 patients underwent laparoscopic CME for right colon cancer, of whom 30 (63.83%) were male. The mean operative time was 143.08 ± 25.46 minutes, with no intraoperative complications reported. The mean intraoperative blood loss was 22.56 ± 11.4 ml, and no conversions to open surgery occurred. R0 resection was achieved in all cases (100%). Postoperative complications included one case of anastomotic fistula (2.22%) and one case of anastomotic bleeding (2.13%). The mean number of harvested lymph nodes was 13.46 ± 6.27, and 86.67% of patients had more than 11 lymph nodes retrieved. The mean postoperative hospital stay was 6.87 ± 0.92 days. Conclusion: Laparoscopic complete mesocolic excision for right colon cancer can be a safe procedure with minimal complications, offers good oncological outcomes, and is feasible for broader application.
