Core Tip

Core tip: This study presents a large cohort of patients operated on with laparoscopic complete mesocolic excisions (CME) for colonic cancer. Five-year survival data are presented. For the first time in a study on laparoscopic CME, it is shown that reoperation for an anastomotic leak has a negative impact on both unadjusted and adjusted survival analysis. The location of the tumour does not impact long-term survival.
