Use of chewing gum in reducing postoperative ileus after elective colorectal resection: a systematic review. Dis colon rectum 2007; 50: 2149¿2157.

Published: 1st January 2007

Authors: Chan MKY, Law WL.

Conclusion

There were five randomized trials including 158 patients for review. Gum chewing significantly speeded return of gut function (passage of flatus, bowel movement) and resulted in a 17.6 per cent reduction in the duration of hospital stay (weighted mean difference –2.4 days, P<0.0001).
