    Abstract:
    Wireless capsule endoscopy (WCE) has emerged as an important diagnostic tool for the evaluation of patients with suspected small intestinal (SI) disease, including obscure gastrointestinal bleeding, Crohn's disease (CD), malabsorptive disorders and SI tumors. Since a great number of patients with CD have small-bowel (SB) involvement, it is important for newly diagnosed patients to undergo an evaluation of the SB, which has traditionally been performed using a radiographic study such as a SB follow-through. The greatest utility of WCE in the evaluation of SB CD has been observed in cases of suspected CD, where the initial evaluation with upper and lower endoscopy as well as traditional radiographic techniques have failed to establish the diagnosis. WCE can detect SB involvement in CD, particularly early lesions that can be overlooked by traditional radiological studies. The sensitivity of diagnosing SB CD by WCE is superior to other endoscopic or radiological methods such as push enteroscopy, computed tomography or magnetic resonance enteroclysis. The utility of WCE in patients with known CD, indeterminate colitis and a select group of patients with ulcerative colitis can help to better define the diagnosis and extent of the disease, and assist in the management of patients with persistent symptoms. A disadvantage of WCE is that the device may be retained in a strictured area of the SB, which may often be present in patients with CD, in addition to a lower specificity. WCE may replace classical studies and become the gold standard for diagnosing SB involvement in patients with suspected, or known CD, in the absence of strictures and fistulae.
