Tu1465 Magnification Endoscopy in Combination with Acetate Spraying and a Narrow-Band Imaging System for Pit Pattern Diagnosis of Colorectal Neoplasms

Pit pattern (PP) classification of colorectal neoplasms using magnification chromoendoscopy with crystal violet staining (CV-MCE) is useful for predicting histological features, but requires labor and time-consumption. Magnification endoscopy with acetate-enhanced narrow-band imaging (acetate-NBIME) is reported to be effective for visualizing superficial mucosal microstructures of early gastric cancers rapidly, and we compared acetate-NBIME with CV-MCE in PP diagnosis of colorectal neoplasms.
