Eosinophilic gastroenteritis presenting with biliary and duodenal obstruction.

Eosinophilic gastroenteritis is a rare disease associated with eosinophilic infiltration of the gastrointestinal tract which can result in gastroduodenal obstruction. Biliary obstruction due to duodenal disease is rare, and the simultaneous occurrence of obstruction of the duodenum and biliary tract has not been previously reported. We now present a patient with abrupt onset of both biliary tract and duodenal obstruction due to eosinophilic infiltration of the muscularis of the duodenum and stomach. The differential diagnosis and unique features of this disease are reviewed.
