Pancreatic fistula: management guided by endoscopic retrograde cholangiopancreatography.

A patient with a persistent external pancreatic fistula was studied by endoscopic cholangiopancreatography (ERCP). The ERCP demonstrated the probable site of the fistula and a high-grade, main pancreatic ductal stricture. This information prompted early, successful surgical correction of the pancreatic fistula by drainage into a Roux-en Y jejunal loop.
