Abnormalities of the opening of the bile duct into the small intestine (sphincter of Oddi) can lead to abnormalities of bile flow. The sphincter of Oddi acts as a "valve" that allows bile to flow from the common bile duct into the intestine.
Primary biliary cholangitis (PBC, formerly referred to as primary biliary cirrhosis) and primary sclerosing cholangitis can lead to progressive scarring of the bile ducts, causing them to become narrow, which results in reduced bile flow through the liver. Eventually, damage and scarring of the liver architecture occur, resulting in liver failure.
