title: Relapsing massive metal bezoar: a case report.
abstract: BACKGROUND
  Bezoars are uncommon findings in the gastrointestinal tract and are composed of a wide variety of materials. We report a case of a relapsing metal bezoar in a man with schizophrenia.
  
  
  METHODS
  A 34-year-old man presented with a history of sub-acute onset of mild diffuse abdominal pain and abdominal distention. Physical examination revealed dullness to percussion in the upper and lower left quadrants. Past medical history was remarkable for epilepsy, schizophrenia and previous abdominal surgery for intestinal occlusion. Plain radiographs revealed objects of metal density contained within a dilated stomach. Celiotomy was performed revealing more than 350 metal objects inside the stomach. The patient was discharged and referred to a psychiatric facility.
  
  
  CONCLUSIONS
  Intestinal occlusion in patients with psychiatric disorders can result from rare causes such as bezoars. This report alerts surgeons to rule out bezoars in the differential diagnosis of intestinal occlusion in people with mental health problems.
