Single- and double-balloon enteroscopy allows complete evaluation of the small bowel and makes distal ileal biopsies feasible. Enteroscopy can also be helpful in the detection of complications of Crohn disease, such as stricture and active disease.

Wireless capsule endoscopy helps to identify involvement of the upper GI tract and may be especially useful in cases of jejunal or proximal ileal anastomotic surveillance. Drawbacks of this technique include the inability to take biopsies and the risk of acute obstruction. If an obstruction is suspected, small bowel imaging should be done before capsule endoscopy.

Guidelines on the use of enteroscopy and endoscopy in the diagnosis and management of IBD are available from the American Society for Gastrointestinal Endoscopy. [83]
