Objective: To investigate the effect of postoperative gum chewing on bowel motility after laparoscopic gynecologic surgery.
Methods: In this randomized controlled trial, patients were allocated to either postoperative gum chewing every 2 hours for 15 minutes or standard postoperative care without gum chewing. The study's primary end points were time to first regular bowel sounds and time to first passage of flatus after surgery. Secondary end points were time of operation to first defecation, patient satisfaction concerning postoperative gum chewing, potential side effects of postoperative gum chewing, and potential effect of gum chewing on postoperative pain therapy.
Results: One hundred seventy-nine patients were included in this trial. We found a significantly shorter interval between surgery and passage of first flatus in the intervention group compared with the control group (median 6.2 hours compared with 8.1 hours; P=.002) and a significantly higher rate of regular bowel sounds 3 hours (76% compared with 47%; P<.001) and 5 hours (91% compared with 78%; P=.01) after surgery. Fewer opioid analgetics were administered to patients allocated to the intervention group (P=.02). There was no significant difference in time to first defecation between groups (median 26.3 hours compared with 29.0 hours, P=.165). Gum chewing was well tolerated and well accepted by patients, and no intervention-related side effects were observed.
Conclusion: Gum chewing seems to have beneficial effects on bowel motility when used as an adjunct treatment in postoperative care after minimally invasive surgery. Gum chewing should be recommended to patients after gynecologic laparoscopic surgery.
