Abstract

Objective: To evaluate early outcomes and postoperative histopathological characteristics in patients with left-sided colon cancer treated by laparoscopic colectomy with complete mesocolic excision. Materials and Methods: A prospective case-series study was conducted on all patients with left-sided colon cancer who underwent laparoscopic colectomy with complete mesocolic excision at Can Tho Central General Hospital from September 2024 to October 2025. Results: The study included 50 patients, comprising 22 males and 28 females, with a mean age of 60.08 ± 11.33 years. Tumors were most commonly located in the sigmoid colon (74%), followed by the descending colon (14%), splenic flexure (8%), and the left third of the transverse colon (4%). Most patients were diagnosed at stage II (60%) and stage III (40%). The mean operative time was 186.37 ± 49.66 minutes, and no intraoperative complications were recorded. Postoperative complications occurred in 8% of cases, mainly surgical site infections. The mean postoperative hospital stay was 7.16 ± 0.97 days. The mean number of harvested lymph nodes was 9.3 ± 4.94; the mean specimen length was 15.7 ± 5.27 cm; and the mean tumor size was 3.61 ± 1.32 cm. R0 resection was achieved in all cases. Conclusion: Laparoscopic colectomy with complete mesocolic excision for the treatment of left-sided colon cancer is a safe and effective procedure, associated with low rates of intraoperative events and early postoperative complications, and yields favorable histopathological outcomes.
