Abstract

Complete mesocolic excision (CME) for the treatment of colon cancer was first introduced in the West in 2008. The first aim of this procedure is to remove the afflicted colon and its accessory lymphovascular supply by resecting the colon and mesocolon in an intact envelope of visceral peritoneum, which holds potentially involved lymph nodes. The second component of CME is a central vascular tie to remove completely all lymph nodes in the central (vertical) direction. In its original iteration, CME was performed via laparotomy, although many centers preferentially perform laparoscopic surgery, with its associated benefits and similar oncological outcomes, as the standard treatment for colonic cancer. Here, we present the surgical techniques for CME in open and laparoscopic surgery, as well as the surgical, pathological and oncological outcomes of the procedure that are available to date. Because there are no randomized control trials comparing CME to “standard” colon surgery, the principles underlying CME seem anatomical and logical, and the results published from the Far East, reporting an 80% 5-year survival rate for Stage III cancer, should guide us.

Core tip: This review presents the most recent knowledge in the field of complete mesocolic excision (CME) for colon cancer treatment and provides key points in both open and laparoscopic surgical techniques, surgical and pathological outcomes, and oncological outcomes of the procedure. The conclusion makes clear that in the absence of randomized control trials comparing CME to “standard” colon surgery, the principles underlying CME seem anatomical and logical, and the favorable long-term results published from the Far East for Stage III colon cancer disease should guide us in the future.
