A Puestow procedure is indicated for the treatment of symptomatic chronic pancreatitis patients with pancreatic ductal obstruction and a dilated main pancreatic duct. The main pancreatic duct needs to be 6mm in diameter in the body of the pancreas for this procedure to be possible.
Limitations
One of the problems that can lead to failure of the Puestow procedure is that pain can persist due to failure to drain the pancreatic duct on the head of the pancreas. A Frey's procedure is an alternativesurgical procedure to the Puestow that allows for better drainage of the head, but pancreatic tissue is removed.
