Narrow-Band Imaging vs. high definition white light endoscopy for optical diagnosis of serrated adenoma in the colorectum: a prospective randomized multicenter trial

Aims The aim of the study was to investigate whether optical predictions of serrated polyp histology using the narrow-band-imaging (NBI) mode is superior to predictions using high-definition-white-light endoscopy (HDWL) in real-time endoscopy.
