Hepatic duct stones are intrahepatic bile duct stones and extrahepatic bile duct stones. The main component of hepatic duct stones is bile pigment stones containing bacteria, which is completely different from the main component of gallbladder stones, so there are no drugs available for lithotripsy. Ursodeoxycholic acid, which is effective for cholesterol stones, is also not effective for hepatic duct stones. However, if hepatic duct stones cause cholangitis, then oral medication can be considered for treatment, mainly for patients with mild inflammation of hepatobiliary dampness and heat, and oral anti-inflammatory and biliary tablets and bile relief tablets can be considered. However, if the stones that cause intrahepatic bile duct stenosis, recurrent cholangitis or liver atrophy, not only the oral medication is ineffective, but even the application of intravenous medication application is also not very effective. In this case, surgery is required and should be followed to remove the stone, release the stricture, control the infection and clear the drainage. The specific surgical procedure should be decided according to the size, number and location of the stones.
