Value of magnifying chromoendoscopy and narrow band imaging (NBI) in classifying colorectal polyps: a prospective controlled study

Abstract

NBI in combination with magnifying endoscopy is a promising tool for the differentiation of neoplastic from non-neoplastic colorectal polyps in vivo without the necessity of using dye. The detection of capillary vessels with NBI allows the evaluation of colorectal lesions based on the vascular patterns with high diagnostic accuracy.
