To investigate morbidity and mortality following complete mesocolic excision (CME) central vascular ligation (CVL) in patients undergoing right colectomy.Data from consecutive elective colectomy at a university-affiliated referral centre were retrospectively analysed. Patients who underwent conventional right-sided colonic cancer surgery (January 2001-April 2009, n = 84) compared to CME/CVL (May 2009-January 2015, 71). The primary end point was anastomotic leak.
