Biliary Fascioliasis in Chronic Calcific Pancreatitis Presenting with Ascending Cholangitis and Biliary Stricture.

Biliary fascioliasis is a rare infection of the hepatobiliary system. In human, it is known to present with two main phases; acute phase (hepatic phase) presenting with abdominal pain or abnormal liver biochemistry then chronic phase (biliary phase) presenting with biliary obstruction or cholangitis. Optimal treatment of biliary fascioliasis consists of endoscopic retrograde cholangiography with removal of the parasite and single oral dose of triclabendazole.
