A Case of Recurrent Infection Caused by a Pancreaticoduodenal Fistula Associated with a Pancreatic Arteriovenous Malformation

Although arteriovenous malformations (AVM) occur frequently in digestive organs, pancreatic AVM is rare. The clinical symptoms of pancreatic AVM are variable and include gastrointestinal bleeding, abdominal pain, jaundice, portal hypertension, pancreatitis, and duodenal ulcer. However, choledochoduodenal or pancreaticoduodenal fistulas complicated with ascending infection and pancreatitis is extremely rare. Herein, we report a case of pancreaticoduodenal fistula associated with a pancreatic AVM that induced recurrent anemia and ascending infection.

A Case of Duodenal Diverticulum Accompanied with Choledochoduodenal and Pancreaticoduodenal Fistulas / 대한소화기학회지

Choledochoduodenal fistula (CDF) occurring simultaneously with pancreaticoduodenal fistula is extremely rare. CDF has known to be a chronic sequela of cholelithiasis, but it is unknown whether pancreaticoduodenal fistula results from chronic cholelithiasis as well. We report a case of cholelithiasis accompanied with choledochoduodenal and pancreaticoduodenal fistula opening into small suprapapillary diverticulum in a 80-year-old woman.
