Interventional radiology is primarily used in the percutaneous drainages of abscesses that complicate Crohn disease, which may obviate the need for surgical resection. [65]

Endoscopic visualization and biopsy are essential in the diagnosis of Crohn disease. Colonoscopy with intubation of the terminal ileum is used to evaluate the extent of disease, to demonstrate strictures and fistulae, and to obtain biopsy samples to help differentiate the process from other inflammatory, infectious, or acute conditions. Given the increased risk of colorectal cancer in patients with IBD, colonoscopy may have a role in cancer surveillance, although the frequency of this practice remains controversial.

Upper gastrointestinal (GI) endoscopy may be used to diagnose gastroduodenal disease, if suspected. This study is recommended for all children, regardless of the presence or absence of upper GI symptoms.
