Cholangitis is an infection of the bile ducts caused by a blockage of gallstones. Cholangitis, with typical symptoms occurring in sequence from biliary colic to fever and jaundice, is called the charcot triad.

Intrahepatic cholangiolithiasis is a fairly common disease, often leaving dangerous complications such as biliary tract infection, hepatitis, cirrhosis, intrahepatic cholangiocarcinoma, sepsis,... Early detection and prompt treatment helps prevent complications of gallstones from occurring.
