Comparing two camera techniques for monitoring bowel pouches in FAP

This study compares two different camera techniques that doctors use to look inside the surgically created pouch in your small intestine. If you have familial adenomatous polyposis and have had pouch surgery, you'll randomly receive either dye-based chromoendoscopy (where dye is sprayed to highlight tissue) or virtual chromoendoscopy (a special camera technology that uses light to improve the image). The goal is to find out which method is better at spotting abnormal growths.

People with familial adenomatous polyposis need regular checks of their pouch because abnormal growths can develop there over time. Doctors currently use two different imaging techniques, but no one knows which one works better at finding these growths early, so this study will provide that answer.
