Characterization of Colorectal Lesions Using a Computer-Aided Diagnostic System for Narrow-Band Imaging Endocytoscopy

Recently, the American Society of Gastrointestinal Endoscopy established the Preservation and Incorporation of Valuable Endoscopic Innovations1 for diminutive colorectal polyps. Preservation and Incorporation of Valuable Endoscopic Innovations suggests that, if an endoscopist diagnoses an agreement of >90% in determining postpolypectomy surveillance intervals and a negative predictive value of >90% with adenomatous histology, pathologic diagnosis might not be necessary. Although magnifying chromoendoscopy,2 narrow-band imaging (NBI),3 endocytoscopy (EC),4 and confocal laser endomicroscopy5 are highly accurate, interpretation of these modalities is difficult for novices.
