Modified Frey procedure
Citation, DOI & article data
Modified Frey procedure is a surgery that includes pancreaticojejunostomy with Roux-en-Y gastric bypass surgery and splenectomy. It is designed to treat patients with chronic pancreatitis and persistent hyperbilirubinemia.
The fundamental technique is similar to the Frey procedure, with a transverse incision to the pancreatic duct from an anterior approach, and then a side-to-side anastomosis between the pancreas and a jejunal loop. The diseased segment of the pancreatic head is removed, uncovering the main pancreatic duct in the pancreatic head, and allowing improved drainage. Additionally, there is communication between the common bile duct and jejunum.
