Capsule camera study: is prep worth it?
NCT ID NCT03351972
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether taking a bowel-cleaning liquid before a capsule endoscopy helps doctors see the small intestine better and find more problems. 230 adults scheduled for the procedure were randomly assigned to get either a split dose, a single morning dose, or no special preparation. The goal was to compare image quality and how often a diagnosis could be made.
