Budesonide for the treatment of obstructive eosinophilic jejunitis.

Eosinophilic gastroenteritis is a rare gastrointestinal (GI) disorder of undetermined origin, characterized by infiltration of eosinophils in the GI tract. Different layers of the bowel wall can be involved and the clinical outlook depends on the area affected. Our subject is a male patient in whom the disease involves the muscular layer causing obstructive jejunitis. The diagnosis was made after surgical resection. A relapse was subsequently treated with short-term intravenous steroids followed by oral budesonide for three months. Treatment was effective with no apparent side effects.
