Chronic pancreatitis is an inflammatory disease resulting in permanent structural and functional changes in the pancreas which manifest clinically as abdominal pain. Operative treatment is indicated when maximal medical therapy has failed, and success in relieving pain is predicated on matching the correct operation (duct drainage, resection, denervation) to the patient's underlying pancreatic anatomy. When the pancreatic duct is dilated (>7 mm in diameter) and the gland morphology is homogeneous, a lateral pancreaticojejunostomy results in pain relief in 87% of patients with a low operative morbidity and mortality rate. A dilated duct with an enlarged pancreatic head requires local resection of the pancreatic head combined with a lateral pancreaticojejunostomy (Frey procedure). Small duct (
