    Causes, incidence, and risk factors

    A biliary stricture is often caused by surgical injury to the bile ducts. For example, it may occur after surgery to remove the gallbladder.

    Other causes of this condition include:

    • Cancer of the bile duct
    • Damage and scarring due to a gallstone in the bile duct
    • Pancreatitis
    • Primary sclerosing cholangitis

    Risk factors include previous biliary surgery, pancreatitis, gallstones, or injury to the intestine.
