Purpose:
To evaluate the safety and feasibility of laparoscopic complete mesocolic excision (CME) via mesofascial separation for left-sided colon cancer.
Methods:
We evaluated prospectively collected data on 65 consecutive patients with stage I-III left-sided colon cancer, who underwent laparoscopic CME between October 2011 and September 2016. After the exclusion of 5 patients who had T4b or other active tumors, 60 patients were the subjects of this analysis. The completeness of CME, preservation of the hypogastric nerve, operative data, pathological findings, complications, and length of hospital stay were assessed.
Results:
CME completeness was graded as the mesocolic and intramesocolic plane in 54 and 6 patients, respectively. The hypogastric nerve was preserved in all patients. A total of 17, 12, 28, and 3 patients had T1, T2, T3, and T4a tumors, respectively. The mean number of lymph nodes retrieved was 16.2, and lymph node metastasis was identified in 22 patients. The mean operative time and intraoperative blood loss were 283 min and 38 ml, respectively. One patient had an intraoperative complication and six patients had postoperative complications. The hospital stay was 12 days.
Conclusion:
Laparoscopic CME via mesofascial separation is a safe and feasible procedure for left-sided colon cancer.
