Value of magnifying endoscopy in classifying colorectal polyps based on vascular pattern

Abstract

The results demonstrate that the superior visibility of capillary vessels by the NBI technique allows the evaluation of colorectal lesions - based on the vascular patterns - with high diagnostic accuracy. In clinical routine, high-definition NBI endoscopy without high magnification may be used to sufficiently predict colorectal polyp histology, and high magnification can additionally facilitate visualization of vascular networks.
