Clinical Validation of BASIC Classification for the Resect and Discard Strategy for Diminutive Colorectal Polyps

Blue-light imaging (BLI) is a chromoendoscopy technique that uses direct (not filtered) emission of blue light with short wavelength (410 nm) to increase visibility of microvascular pattern and superficial mucosa.
