In most patients with Crohn's disease, diagnostic gastrointestinal lesions are located in the small bowel, which is not easily accessible to direct investigation. This commentary focuses on an article by Solem et al., which compared the utility of four primary small-bowel imaging modalities (CT enterography, ileocolonoscopy, capsule endoscopy, and small-bowel follow-through) in diagnosis of active small-bowel Crohn's disease. Capsule endoscopy had lower diagnostic specificity than the other techniques. This result, in conjunction with the need to perform preliminary small-bowel radiography to detect asymptomatic, partial, small-bowel obstructions, makes capsule endoscopy a poor choice as a first-line test for Crohn's disease. We concur with Solem et al.'s opinion that a combination of two of the other available imaging methods is the best diagnostic option for small-bowel Crohn's disease, although the choice of which two to use should be based on the facilities and expertise that are available locally.
