[The role of capsule endoscopy in suspected Crohn's disease].

Capsule endoscopy (CE) revolutionized the small bowel examination. We emphasize the role of CE in suspected Crohn's disease, studying 24 investigations performed in the Institute of Gastroenterology and Hepatology. The global diagnostic yield was 54%, the specific diagnostic yield for Crohn's disease was 37.5%, the specificity was 100% and the retention rate was 4.1%. For maximum accuracy and efficiency, unitary administration and diagnostic criteria are needed, and for minimising the risk of complications, specific prior investigations would be suitable.
