Comparison of outcomes of complete mesocolic excision with conventional radical resection performed by laparoscopic approach for right colon cancer

Abstract

Background: This retrospective study compared the outcomes of laparoscopic complete mesocolic excision (CME) guided by superior mesenteric artery with laparoscopic conventional radical resection (CRR) performed for right-sided colon cancer. Methods: Patients with right-sided colon cancer underwent CME (n=107; January 2011 to December 2015) or CRR (n=60; January 2008 to December 2010). Results: The 2 groups were comparable regarding age, gender, body mass index, maximum tumor diameter, and tumor stage. In the CME group, the distances between the tumor and the high vascular tie (HVT; 12.6 cm), and between the closest bowel wall and HVT (10.4 ±0.9 cm) was significantly greater than that of the CRR group (11.5 cm and 9.3±1.0 cm, respectively; P0.05). Conclusion: CME for right-sided colon cancer guided by superior mesenteric artery has similar short-term outcomes, higher lymph node yield, and higher 3-year overall survival compared with CRR.
