Diagnosis of Eosinophilic Enteritis With Video Capsule Endoscopy and Double Balloon Enteroscopy With Favorable Response to Corticosteroids.

Eosinophilic enteritis is a rare disease with nonspecific symptoms, often representing a diagnostic challenge. Video capsule endoscopy (VCE) has enabled examination of the full small bowel. However, capsule retention is an unfortunate complication. We present the case of a female patient admitted for abdominal pain. Appendectomy without resolution of symptoms was performed. A normal computed tomography and magnetic resonance imaging were obtained. The diagnosis was made by VCE and double balloon enteroscopy with biopsy. Asymptomatic capsule retention was resolved after corticosteroid therapy. The patient showed a favorable clinical and endoscopic response, confirmed through a second VCE after 3 months of treatment.
