Clinical Trial Summary

This prospective bicentric trial aims to evaluate the diagnostic performance of the characterization of scalloped polyps less than 20 millimeter in NBI (Narrow Band Imaging) in patients with screening colonoscopy.

The NBI is a so-called "virtual" electronic staining technique available on conventional OLYMPUS endoscopes without additional intervention.

The colonoscopy procedure for each patient will not be different from a conventional colonoscopy examination with excision of all polyps visualized and anatomopathological analysis, except for a short time of analysis in NBI for each polyp detected before excision to classify the polyp in existing endoscopic classifications (ie NICE classification for adenomatous polyps and WASP classification for festooned polyps).
