Experience and Enhancement: Improving Colonoscopic Polyp Detection

The study looks at 2 hypotheses in 2 patient groups: 1. Are more experienced endoscopists better at detecting subtle lesions (polyps) on the lining of the colon (large bowel) than less experienced endoscopists? 2. Do existing and new techniques that can highlight lesions on the lining of the bowel improve endoscopists ability to spot them? This will be tested using video footage of endoscopies from 2 patient groups: those with a normal colon linig and those with colitis (bowel lining inflamation)
