Eksperimentel: High Definition NBI Colonoscopy
Use of high definition narrow band imaging colonoscopy during examination for polyp detection.
The same intervention is used on both arms: the Olympus Colonoscope CFHQ190AL, a technically improved colonoscope with close focus high definition narrow band imaging.

Placebo komparator: High Definition White Light Colonoscopy
Use of high definition white light colonoscopy during examination for polyp detection.
The same intervention is used on both arms: the Olympus Colonoscope CFHQ190AL, a technically improved colonoscope with close focus high definition narrow band imaging.
