Abstract
Capsule endoscopy (CE) is increasingly used in patients with suspected or known Crohn's disease (CD). To determine the diagnostic yield of CE and the distribution of small-bowel (SB) lesions in symptomatic patients with known CD. Retrospective review of CE procedures performed in patients with CD between 2001 and 2005 in a tertiary care center. One hundred thirty-four patients with an established diagnosis of CD and symptoms suggestive of active disease. Swallowing the capsule. Diagnostic yield of CE and distribution of SB lesions in patients with CD. One hundred forty-six CE procedures were performed on 134 CD patients. Fifty-two (39%) of 134 patients had CE findings diagnostic of active CD (> 3 ulcerations), and 17 (13%) had findings suggestive of active CD (< or = 3 ulcerations). Fifty-seven (42%) patients had normal findings, and 6% had normal but incomplete studies. The distribution of SB lesions was 32% in the duodenum, 53% in the jejunum, 67% in the proximal ileum, and 85% in the distal ileum. CE was comparable to ileoscopy in detecting ileal ulcerations (55% vs 48%), but superior to SB follow-through in detecting CD lesions in the SB (incremental yield of 32%; 95% CI, 9%-54%; P = .0017). Retrospective study from a single center. CE identified SB lesions in approximately half of symptomatic CD patients. Large-scale prospective studies are needed to evaluate whether positive CE findings may affect disease outcomes.
