Gum chewing enhances early recovery of bowel function following transperitoneal abdominal aortic surgery

Abstract

Background and purpose: Postoperative bowel dysfunction is still a major unsolved problem following transperitoneal abdominal aortic surgery. We conducted this study to establish if gum chewing during the postoperative period promotes recovery of bowel function following abdominal aortic surgery.

Methods: The subjects were 44 patients who underwent elective abdominal aortic surgery. The patients were allocated to a control group (n = 21), who received standard postoperative care, or a "gum group" (n = 23), who received standard postoperative care and were also given gum to chew three times a day from postoperative day (POD) 0-5.

Results: The patient characteristics, intraoperative, and postoperative care were equivalent in both groups. Flatus was passed on POD 1.49 in the gum group and on POD 2.35 in the control group (P = .0004) and the time to oral intake was 3.09 days in the gum group and 3.86 days in the control group (P = .023). The number of days to full mobilization in the hospital room was 3.35 versus 5.59 for the gum and control groups, respectively (P < .0001).

Conclusions: Gum chewing enhances early recovery of bowel function following transperitoneal abdominal aortic surgery. Moreover, it is a physiologically sound, safe, and an inexpensive part of the postoperative care.
