Biliary obstruction in chronic pancreatitis: indications for surgical intervention.

A syndrome of distal common bile duct obstruction secondary to the fibrotic effects of chronic pancreatitis has been recognized for some time. A group of ten characteristic patients, seven of whom have undergone surgery, is discussed. The diagnostic techniques and surgical procedures are presented, and the results are analyzed. Three patients with the syndrome were not operated upon and one improved spontaneously. The typical patient was a male alcoholic, average age 48 years, with a history of chronic, relapsing pancreatitis and abdominal pain. The most consistently abnormal laboratory value is a markedly elevated alkaline phosphates level. Endoscopic retrograde pancreaticocholangiography and transhepatic cholangiography are the most useful diagnostic procedures. Fifteen per cent of the most useful diagnostic procedures. Fifteen per cent of the patients operated upon required emergent surgery for acute cholangitis and sepsis. Another 29 per cent required prompt intervention for progressive hepatic failure secondary to biliary cirrhosis. The authors advocate an aggressive approach to establish biliary drainage in the presence of acute cholangitis or biliary cirrhosis. If a dilated pancreatic duct can be demonstrated and abdominal pain is the principal problem a direct procedure on the pancreas is needed.
