Tu1405 The Learning Curve for in-Vivo Characterisation of Small Colonic Polyps: Number Needed to Train (NNT) Is 200 Polyps

      Chromoendoscopy, Narrow Band Imaging (NBI) and Flexible Spectral Imaging Colour Enhancement (FICE) have been shown to be effective in the in-vivo characterisation of small colonic polyps. The learning curve for a new technology for real-time characterisation of small colonic polyps has not been determined. The ASGE has set performance criteria for ‘resect and discard’ and ‘do not resect’ policies for diminutive colonic polyps.
