Abstract BACKGROUND: Capsule endoscopy (CE) fails to reach the caecum in approximately 20\% of patients. Data suggest that chewing-gum, simulating sham feeding, provokes the cephalic phase of gastrointestinal (GI) motor response and may increase GI motility. AIM: To determine whether chewing-gum increases the ability of CE reaching the caecum. METHODS: Prospective, randomized, single-blinded controlled trial. Ninety-three consecutive patients were randomized either to use chewing-gum (n = 47) or not (n = 46). All patients received the identical bowel preparation. Patients chewed one piece of gum for approximately 30 min every 2 h. Two blinded gastroenterologists examined all studies. The number of CE that reached the caecum within 8-h, gastric transit time (GTT) and small bowel transit time (SBTT) were evaluated in all patients. RESULTS: The CE percentage passed into the caecum was higher in the chewing-gum group compared with those in the other (83.0\% vs. 71.7\% respectively, P = 0.19). Both GTT and SBTT were significantly shorter in the chewing-gum vs. control group [40.8 min (interquartile range: 21-61 min) vs. 56.1 min (interquartile range: 22-78 min) (P = 0.045) and 229.1 min (interquartile range: 158-282 min) vs. 266.2 min (interquartile range: 204-307 min) (P = 0.032) respectively]. Chewing-gum did not adversely affect CE image quality. CONCLUSIONS: Chewing-gum significantly reduces GTT and SBTT during CE. Its use may improve the likelihood of the capsule reaching the caecum without affecting CE image quality.
