Official Title: Randomised, Controlled Trial of Narrow Band Imaging (NBI) Versus Standard Endoscopy for Adenoma Detection
Brief Summary:
Does a new colonoscopic viewing technique called narrow band imaging (NBI) help doctors detect more patients with at least one pre-cancerous polyp (adenoma) than conventional colonoscopy using white light alone?
May 2007 protocol minor amendment: additional viewing by endoscopists outside St Mark's ro allow assessment of inter- and intra-observer variability.
