Answer

The development of flexible, small-caliber endoscopes has allowed colonoscopic evaluation of pediatric patients of all ages, including infants. Colonoscopy with several colonic and terminal ileal biopsies is invaluable and considered a standard in the diagnosis of Crohn disease (see the image below).
