Puestow procedure
Encyclopedia
The Puestow procedure is a surgical technique
used in the treatment of chronic pancreatitis
. It involves a side-to-side anastomosis
of the pancreatic duct
and the jejunum
.
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.
is an alternative surgical procedure to the Puestow that allows for better drainage of the head, but pancreatic tissue is removed.

Jejunum
The jejunum is the middle section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear and the terms middle intestine or mid-gut may be used instead of jejunum.The jejunum lies between the duodenum...

Indications
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 procedureFrey's procedure
