Risk for morbidity, anastomotic/suture leakage and 90-day mortality according to the number of identified independent risk factors.

Number of Risk Factors	In-Hospital Major Morbidity *		Anastomotic/Suture Leakage **		90-Day Mortality ***
	n	Risk	n	Risk	n	Risk

* four independent risk factors for morbidity: presence of any comorbidity, impaired preoperative general condition, a perforation of the right hemicolon and the need for an intraoperative blood transfusion. ** one independent risk factor for anastomotic/suture leakage: presence of any comorbidity. *** three independent risk factors for 90-day mortality: NRS ≥ 3, impaired preoperative general condition and the need for an intraoperative blood transfusion.
