title: Superior mesenteric artery syndrome: an unusual cause of Watson biopsy capsule retention.
abstract: The prolonged intestinal retention of a Watson biopsy capsule in a 12-year-old girl with chronic diarrhea is reported. Radiological investigation showed a duodenal obstruction due to superior mesenteric artery syndrome. A preliminary barium study of the upper gastrointestinal tract, before performing blind intestinal biopsies, may decrease the incidence of similar complications.
