Early enteral feeding is beneficial for patients after pelvic exenteration surgery: A randomized controlled trial. Issue 2 (14th May 2021) - Hogan, Sophie
Abstract: Background: Postoperative feeding practices vary after pelvic exenteration surgery because of the lack of nutrition research in this specific surgical area. Postoperative ileus (POI) is common after pelvic exenteration surgery, and early enteral feeding is often avoided because of the lack of evidence and the belief that this may induce POI in this patient cohort. The aim of this study was to determine the effects of early enteral feeding after pelvic exenteration surgery on return of bowel movement and POI. Methods: A randomized controlled trial was conducted with patients undergoing pelvic exenteration surgery from November 2018 to June 2020. Forty participants received standard nutrition care (parenteral nutrition) and 47 participants received trophic enteral feeding (20 ml/h) via a nasogastric tube, in addition to standard care, until participants were upgraded to free fluids. Time to first bowel movement and rates of POI were the main outcome measures. Results: There was no significant difference between arms for time to first bowel movement; however, POI rates were significantly less in participants who were enterally fed ( P = .036) in the per‐protocol analysis. Regressions showed that the longer patients were restricted from an oral diet after surgery, the greater the time was to first bowel movement and the greater the postoperative complication rates ( P < .0005). Conclusions: Early enteral feeding can be commenced safely to improve gastrointestinal function after pelvic exenteration surgery.
