The best indication for performing wireless capsule endoscopy in patient with inflammatory bowel disease is suspected Crohn's disease. Capsule can detect early small bowel involvement missed by other imaging techniques.
Sensitivity capsule endoscopy is higher than for push-enteroscopy, CT/MR enteroclysis. Capsule endoscopy is useful in distinguishing between ulcerative and Crohn's collitis and can better detect extent of disease.
Capsule retention can occur. Stenosis is contraindication for capsule endoscopy.
Scores for assessing the activity or severity of Crohn's disease by capsule endoscopy is not widely accepted and validated prospectively. Further research is needed in the evaluation of diagnostic yield of capsule endoscopy in IBD patient.
