Definition Return to top
Cholangitis is an infection of the common bile duct, the tube that carries bile from the liver to the gallbladder and intestines. Bile is a chemical made by the liver that helps digest food.
Causes Return to top
Cholangitis is usually caused by a bacterial infection, which can occur when the duct is blocked by something, such as a gallstone or tumor. The infection causing this condition may also spread to the liver.
Risk factors include a previous history of gallstones, sclerosing cholangitis, HIV, narrowing of the common bile duct, and, rarely, travel to countries where you might catch a worm or parasite infection.
