Biliopancreatic fistulas complicating pancreatic pseudocysts: a report of three cases demonstrated by endoscopic retrograde cholangiopancreatography.

Three patients were found to have fistulation of the pancreatic and common bile ducts, complicating chronic pancreatitis in one patient and acute pancreatitis in two patients. Closure of the fistula was achieved with biliary and pancreatic stenting in one patient; the other two patients were treated surgically because endoscopic treatment had failed. The clinical and radiological features of this exceptional complication are presented, with a brief review of the topic.
