Video tutorial may boost colonoscopy prep quality
NCT ID NCT07355777
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two ways of explaining colonoscopy prep: a standard talk with the doctor versus watching a video tutorial at home. About 574 adults having their first colonoscopy will take part. The goal is to see if the video leads to better bowel cleanliness and helps doctors find more polyps.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- video tutorial
- What this could lead to
- If it works, this could show that a simple video helps people prepare better for colonoscopy, leading to clearer results.
- What could go wrong
- This is a small, early-stage study. The video may not improve prep quality much, and results might not apply to everyone.
