Having patients chew gum reduces the time to first flatus and time to first bowel movement, as well as the length of hospitalization by about half a day. (Strength of Recommendation: A, based on consistent, good-quality patient-oriented evidence.)
Postoperative ileus is common and may lead to prolonged hospitalization among other complications. Enhanced Recovery After Surgery techniques, including optimal pain control by epidural and local anesthesia, minimally invasive techniques, and aggressive postoperative rehabilitation, have been shown to reduce the risk of ileus.1 However, early postoperative feeding, one aspect of the Enhanced Recovery After Surgery program, may increase the risk of vomiting. Having patients chew gum in the postoperative period is not an aspect of the program, but it may decrease the risk of ileus by stimulating the cephalovagal system and intestinal motility while encouraging the
