The Effectiveness of Chewing Gum in Influencing Capsule Endoscopy Transit Time

Not Applicable

Completed

• Conditions: Gastric Transit Time; Small-bowel Transit Time

• Registration Number: NCT03815136
• Lead Sponsor: The First Affiliated Hospital of Zhejiang Chinese Medical University

Brief Summary

The purpose of this study is to determine the effect of chewing gum, during the first one hour of examination in patients undergoing CE for GTT and SBTT time and the proportion of cases with complete small bowel examination and gastroscopy intervention.

Detailed Description

The participants will include patients who need to a capsule endoscopy (CE) in this unit. The investigators will include 200 participants who had a CE at our centre based on the gastric transit times. These will be randomly divided into two groups. The participants (chew chewing gum) and the controls (do not chew chewing gum).
