Capsule Endoscopy for Celiac Disease

AbstractCeliac disease (CD) is an immune-mediated enteropathy that is characterized by intraepithelial lymphocytosis, crypt hyperplasia, and villous atrophy. Prevalence is high and has been estimated to range between 0.5% and 1.5%. Capsule endoscopy (CE) has a sensitivity and specificity of approximately 90%. CD is an important differential diagnosis for diagnostic workup for anemia, malabsorption, or diarrhea, and must be recognized reliably by the investigator. Moreover, CE is the preferred method to screen for complications in CD, such as enteropathy-associated T-cell lymphoma, ulcerative jejunitis, and small bowel adenocarcinoma.
