common duct obstruction in patients with intractable pain of chronic pancreatitis.
Fibrosis of chronic pancreatitis can cause obstructive jaundice by compressing the intrapancreatic portion of the common bile duct. The frequency and clinical manifestations of common bile duct stricture from symptomatic chronic pancreatitis have been evaluated in 26 patients undergoing lateral pancreaticojejunostomy for intractable pain between 1974 and 1980. Four patients (15%) had a stricture with partial obstruction of the common duct in addition to pancreatic duct obstruction. Three of the four strictures were identified prior to operation by ERCP. The fourth developed biliary obstruction six months after pancreaticojejunostomy. Slight elevation of alkaline phosphatase was common and occurred in 12 of 22 patients with chronic pancreatitis without biliary obstruction. Alkaline phosphatase was elevated greater than four times normal in three of the four patients with a biliary stricture. Elevation of total and direct serum bilirubin occurred only in patients with stricture of the distal common duct. A waxing and waning picture of jaundice was seen in these four patients. When a fixed smooth stricture of the common duct is demonstrated in a patient with symptomatic chronic pancreatitis, drainage of the biliary tree should be combined with pancreatic duct drainage in order to prevent cholangitis, biliary cirrhosis, diagnostic confusion with pancreatic carcinoma, and persistence of pain.
