Is there any difference in clinical outcome according to the tumor subsite location within the colon when performing laparoscopic complete mesocolic excision?
6th Global Gastroenterologists Meeting
Jun-Gi Kim, Min Ki Kim, Dae Youn Won, In Kyu Lee, Hyeon-Min Cho and Bong-Hyeon Kye
Aim: Procedures of laparoscopic colectomy are different from each other according to the tumor subsite within the colon, and
short-and long-term outcomes of laparoscopic complete mesocolic excision (CME) and central vascular ligation (CVL) for
colon cancer have never been compared based on the tumor location.
Method: Clinical data of patients who received laparoscopic colectomy for primary colon cancer between April 1995 and
December 2010 from single surgeon were retrospectively reviewed. Data were analyzed and compared among three groups;
patients whose tumor location was between ascending and proximal transverse colon (A, n=142), mid transverse and
descending colon (TD, n=55), and sigmoid and rectosigmoid colon (S, n=214).
Results: Female patients were more common in group A (53.5% vs. 38.2% vs. 39.3%, p=0.020). Other baseline characteristics
were comparable. Operative time was shorter in group S than another groups [245(145-855) vs. 279(150-485) vs. 295(145-
455) min, p=0.000]. There were no differences among the groups in perioperative complication and patient recovery. Local
recurrence rate was comparable among the groups (4.2% vs. 5.5% vs. 3.3%, p=0.594) for the median follow up period of 73(0-
120) months.
Conclusion: Laparoscopic CME and CVL for colon cancer can be performed with comparable short- and long-term outcomes
regardless of tumor subsite except for the operative time.
