Answer

In capsule enteroscopy, the patient swallows an encapsulated video camera that transmits images to a receiver outside the patient. It is most commonly used for finding obscure sources of gastrointestinal (GI) blood loss, the images can find ulcerations associated with Crohn disease if upper endoscopy and colonoscopy are unrevealing. In one study, the detection rate of abnormalities was 70.5% for patients with suspected small bowel disease, and the diagnostic yield for patients with obscure GI bleeding was higher (85.7%) than that for patients with abdominal pain or diarrhea (53.3%). [70]

Capsule enteroscopy may also aid in the diagnosis of small bowel Crohn disease when the standard diagnostic workup with colonoscopy and upper endoscopy is negative. [1]
