White-light endoscopy has been considered ineffective for distinguishing adenomatous from hyperplastic histology in colorectal polyps. Several studies have shown that narrow-band imaging (NBI), or blue-light illumination, enables accurate differentiation. In a previous study, for which I was the sole investigator, NBI without high-magnification colonoscopy allowed for polyp histology to be identified with high confidence on the basis of endoscopic appearance alone and for 80% of polyps ≤5 mm to be resected and discarded; surveillance intervals were assigned correctly in 98% of cases (Gastroenterology 2009; 136:1174).
In a new prospective study, researchers evaluated the usefulness of NBI for assigning surveillance intervals using a “resect a…
