Intragastric gallstone-induced bezoar: an unusual cause of acute gastric outlet obstruction.

Author information

  • 1Department of Medicine, Mercy Catholic Medical Center, Philadelphia, PA USA.


Bezoars are an uncommon cause of acute gastric outlet obstruction. To our knowledge, this is the first report of a bezoar formed around a gallstone that migrated to the stomach via a cholecystogastric fistula. Our patient was a 42-year-old African American woman with long-standing type 2 diabetes. We suspect that diabetic diathesis was the major factor responsible for producing the pathologic derangement of the gallbladder and stomach, which led to development of the bezoar and serious complications.
