Acute pancreatitis and pancreatic fistula formation

Abstract

Abstract The cause, management and outcome of 23 patients with a pancreatic fistula following acute pancreatitis are reviewed. Nineteen patients developed an external fistula following necrosectomy or drainage of a pancreatic abscess or pseudocyst; four of these patients died. In the 15 survivors spontaneous closure occurred in 11 cases with low output fistulae; operative intervention was needed in the four cases with high output fistulae. Four patients with internal fistulae had not undergone previous surgery; two of them had a pancreaticopleural fistula with associated pancreaticogastric fistulae, while two had pancreatic ascites. All four of these patients required surgical intervention and one died.
