Impact of post-operative paralytic ileus on post-operative outcomes after surgery for colorectal cancer: a single-institution, retrospective study.

Purpose: Post-operative paralytic ileus (POI) occurs after surgery because of gastrointestinal dysfunction caused by surgical invasion. We therefore investigated the frequency of POI after laparoscopic colorectal surgery in patients with colorectal cancer using a strictly defined POI diagnosis and identified associated risk factors.

Methods: Patients who underwent initial laparoscopic surgery for colorectal cancer between January 2014 and December 2018 were included.
