Development and validation of a simple classification system for in vivo diagnosis of colorectal polyps using the newly introduced Optical Enhancement (OE) technology

Introduction: Most recently, Optical enhancement (OE) has been introduced as a novel endoscopic imaging technique that adjusts emitted light to enhance mucosal vascular pattern and surface pattern morphology. This study assessed for the first time the utility of OE to predict colorectal polyp histology. Aims: Primary objective was the development and validation of a simple classification system allowing differentiation of hyperplasic and adenomatous colorectal lesions by using OE. Material and methods: In the first phase, the capacity of experienced endoscopists to predict the histology of colorectal polyps was…
