Video-based education to improve colonoscopy preparation
Official title: Evaluation of the Effect of Video-Based Education on Bowel Preparation Before Colonoscopy
Run by Eskisehir Osmangazi University · NCT07229066 · Data updated 2026-11-12
We will test whether watching a short instructional video helps adults scheduled for colonoscopy get a cleaner bowel before the procedure.

Is this trial a fit for you?
✓Likely a good fit
Adults scheduled for outpatient colonoscopy who have never had a colonoscopy and who (or a household member) can use a smartphone app are ideal candidates.
✕Probably not a fit
Patients with major abdominal surgery, suspected gastrointestinal obstruction, impaired swallowing, mental disorder or communication difficulties, congestive heart or kidney failure, or those who are pregnant or breastfeeding may not benefit or will be excluded.

What this trial studies
Adults scheduled for outpatient colonoscopy who have not previously undergone the procedure will receive video-based education about dietary restrictions and laxative use delivered via a smartphone application. The intervention group will watch the video prior to their procedure and outcomes will be compared to standard preparation instructions. Study staff will record bowel preparation quality at the time of colonoscopy and monitor procedure completion and need for repeat examinations. Common exclusions include major abdominal surgery, suspected GI obstruction, swallowing or communication disorders, significant heart or kidney failure, pregnancy, and breastfeeding.
Why it matters
Potential benefit: If successful, video education could reduce inadequate bowel preparations, lower the number of repeat procedures, and improve detection of precancerous lesions.
How similar studies have gone: Previous studies have generally shown that video-based education can improve bowel preparation compared with written or verbal instructions, although results vary by setting and delivery.
