Assessment of Frey procedures: Japanese experience

Background/Purpose The Frey procedure, the coring out of the pancreatic head and longitudinal pancreaticojejunostomy, is a safe, easy, and reliable method to solve most of the problems associated with chronic pancreatitis. During long-term follow up, unexpected relapse in the pancreatic tail was encountered. The pattern of failure and the rationale for a new procedure to treat or prevent such relapse were investigated.
