✦ Synopsis

Background: Colonoscopy is the preferred screening method for colorectal cancer. However, it has a substantial miss rate for colon polyps, and several techniques have been attempted to improve this limitation. Narrowband imaging (NBI) is a novel technology that enhances the visualization of surface mucosal and vascular patterns.

Objective: The aim of this study was to determine the detection rate of additional polyps by NBI after removal of polyps visualized by standard white light colonoscopy (WLC) and to correlate the surface mucosal and vascular patterns with polyp histologic diagnosis.

Design: This was a prospective pilot feasibility study.
