Is this trial a fit for you?
✓Likely a good fit
Adults aged 17–85 undergoing open gastrointestinal (elective or emergency) surgery who can provide informed consent and do not meet exclusion criteria.
✕Probably not a fit
Patients with metabolic or endocrine disorders, renal disease, chronic constipation or neuromuscular disorders, those on medications that affect gut motility, with dental prostheses, or having laparoscopic surgery are unlikely to benefit or be eligible.

What this trial studies
This randomized controlled trial will enroll 96 adults undergoing open gastrointestinal surgery and use block randomization to assign participants to a chewing-gum intervention or a control group. The intervention group will begin chewing glucose-containing gum six hours after surgery as a form of sham feeding. Primary outcomes include time to first bowel sounds, passage of flatus, and first defecation, with statistical comparisons between groups. The study aims to determine whether postoperative gum chewing shortens the duration of postoperative ileus and speeds recovery of gut motility.
Why it matters
Potential benefit: If successful, chewing gum could offer a simple, low-cost way to speed return of bowel function, reduce discomfort, and shorten hospital stays.
How similar studies have gone: Previous randomized trials and meta-analyses of gum chewing after abdominal surgery have reported modest but consistent reductions in time to first flatus and bowel movement, so this approach has supportive prior evidence.
