¹Left-sided colonic obstruction is defined as an obstruction caused by tumor distal to the splenic flexure (including rectal cancer);

²Rectal cancer is defined as a cancer located within 12 cm of the anal verge. ASA: American Society of Anesthesiologists; BMI: Body mass index; CR-POSSUM: ColoRectal Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity; ERAS: Enhanced recovery after surgery.
