The operation involves creating a longitudinal incision along the pancreas while the main pancreatic duct is filleted open longitudinally from the head of the organ to its tail. The duct and pancreas are then attached to a loop of the small intestine (pancreaticojejunostomy), which is oversewn to the exposed pancreatic duct in order to allow its drainage. When used in the appropriate setting, pain from chronic pancreatitis can improve. One advantage of this procedure compared to a Frey's procedure is that pancreatic tissue is preserved, which may be of critical importance in patients with exocrine or endocrine insufficiency from their chronic pancreatitis.
