Extended Complete Mesocolic Excision in right-sided Colon Cancer - An Overview

Surgical resection with systematic lymphadenectomy remains the standard of care for non-metastasised colon cancer. After the article of Hohenberger et al. in 2009 describing the surgical technique of complete mesocolic excision (CME), D2 lymphadenectomy has been called into doubt after the finding of a better oncological outcome. However, there has been also a controversial discussion about the oncological value of CME, since intraoperative complications may increase. Additional evidence has been provided in recent years from randomised controlled multicentre studies showing that the reported improved oncological long-term outcome after CME is more than questionable. The reported increased rate of intraoperative (vascular) complications could be not confirmed.
