ObjectiveTo assess whether chewing gum prevents postoperative ileus after laparotomy for benign gynecologic surgery.MethodsA randomized study was conducted from December 1, 2010, to February 29, 2012. Patients scheduled to undergo laparotomy were randomly assigned to receive chewing gum or routine care after surgery. A chart review was performed to establish incidence of nausea and vomiting, use of antiemetics, cases of postoperative ileus (≥2 episodes of emesis of 100 mL or more, with abdominal distention and absence of bowel sounds), and time to discharge. Inpatient surveys recorded the time to specific events.ResultsA total of 109 patients were randomly assigned to receive chewing gum (n=51) or routine postoperative care (n=58). Fewer participants assigned to receive chewing gum than routine care experienced postoperative nausea (16 [31.4%] versus 29 [50.0%]; P=0.049) and postoperative ileus (0 vs. 5 [8.6%]; P=0.032). There were no differences in the need for postoperative antiemetics, episodes of postoperative vomiting, readmissions, repeat surgeries, time to first hunger, time to toleration of clear liquids, time to regular diet, time to first flatus, or time to discharge.ConclusionChewing gum after laparotomy for gynecologic surgery is safe and lowers the incidence of postoperative ileus and nausea.
