Percutaneous embolization of the distal pancreatic duct to treat intractable pancreatic juice fistula.

Pseudocysts and post-necrotic collections of the pancreas are sometimes treated by percutaneous drainage. In cases of post-necrotic collection, intractable pancreatic juice fistula is often formed by disruption of the main pancreatic duct in the necrotized region. We radically treated intractable pancreatic juice fistulae by selective cannulation into the distal pancreatic duct via the route for percutaneous drainage of post-necrotic collections to extinguish the exocrine function of the caudal pancreas. We performed this procedure in two patients in whom the major pancreatic duct was damaged at the body of the pancreas, which was extensively necrotic. Although mild symptoms of acute pancreatitis appeared in both patients after the first procedure, they recovered without severe side effects. Neither recurrence of pancreatic juice fistulae nor reduction of the glucose tolerance was caused by removing the exocrine function of the caudal pancreas in either patient 32 and 24 months after treatment, respectively. This method is an effective treatment modality with which to treat intractable pancreatic juice fistulae with damage of the main pancreatic duct.
