Expediting return of bowel function after colorectal surgery

BackgroundPostoperative ileus is the main determinant of the length of hospital stay after colorectal surgery. Our objective was to analyze modifiable factors, including polyethylene glycol administration, associated with the return of bowel function.MethodsA retrospective review of all patients who underwent elective open partial colectomy from 2004 to 2006 at a single institution.ResultsThe time to the first bowel movement with and without oral intake within 48 hours postoperatively was 76 hours versus 134 hours (P < .001); with and without polyethylene glycol administration it was 73 hours versus 94 hours (P = .001); and with and without frequent ambulation it was 78 hours versus 95 hours (P = .012). With postoperative nasogastric tube drainage, the time to the first bowel movement was 22 hours longer (P = .002).ConclusionsThese data confirm previous findings supporting no nasogastric tube drainage, early feeding, and frequent ambulation after colorectal surgery. Additionally, our data suggest a strong association (P = .001) between the use of polyethylene glycol and the early return of bowel function.
