Pancreaticogastrostomy: the preferred operation for pain relief in chronic pancreatitis.

We present the results of surgery in 53 patients with intractable pain due to chronic pancreatitis associated with pancreatic duct dilatation. Using a limited mucosal to mucosal anastomosis over a silastic T tube the main pancreatic duct was drained in 33 patients into a Roux-en-Y jejunal loop (pancreaticojejunostomy, PJ) and in 20 patients into the stomach (pancreaticogastrostomy, PG). There was one postoperative death in the PJ group and none in the PG group. All patients were followed up for a minimum of four years. There was significantly greater pain relief in the PG group both at 1 (P less than 0.01) and 4 years (P less than 0.05) after surgery. We argue that PG is the operation of choice to relieve intractable pain in most patients with chronic pancreatitis associated with duct dilatation.
