Five cases that illustrate the spectrum of biliary complications of pancreatitis and pancreatic pseudocyst are discussed. Obstructive jaundice, hemobilia, and bilious ascites were the major problems in these five patients. Sonography, transhepatic cholangiogram, endoscopic retrograde cholangiopancreatography, operative cholangiography, and arteriography are important in establishing the diagnosis and planning the treatment. Three patients had biliary obstruction caused by chronic pancreatitis, a pancreatic pseudocyst, or both. Two patients had a fistula between the common duct and the pseudocyst. Simple decompression of the pseudocyst was curative for only one patient. Three patients required decompression of the biliary tract, which emphasizes the need for intraoperative cholangiography. One patient required a Whipple operation to control hemorrhage but died in the immediate postoperative period. The operative findings determine the specific procedures for biliary tract decompression and pseudocyst drainage.
