Cholangitis
Definition:
An inflammation of the common bile duct.
Causes, incidence, and risk factors:
A bacterial infection in the bile duct and its bile is the usual cause of cholangitis. Bacterial infection is caused by obstruction of the duct by a gallstone; tumor; or in some parts of the world, by a fluke or a worm. The infection may spread to the liver. The risk factor is a previous history of cholelithiasis (gallstones). Cholangitis occurs in approximately 1 out of 10,000 people.
