Values are n (%) unless otherwise indicated. Leakage refers to grade C (need for relaparotomy). No chronic anastomotic sinuses were reported. Two intraoperative complications (bleeding and superior mesenteric vein (SMV) injury) occurred in one patient in the CME group. CME, complete mesocolic excision. *χ2test, except †? test.
