Bile duct calcification does not need treatment, but the situation of intrahepatic bile duct stones is complicated, which is generally divided into primary (proximal cholestasis, infection and gallstone formation caused by distal stenosis of intrahepatic bile duct) and secondary (entry from extrahepatic bile duct, that is, choledocholithiasis moves into intrahepatic bile duct).

Treatment: Secondary is relatively simple, because there is no intrahepatic bile duct stenosis, and it can be treated like choledocholithiasis, such as ERCP stone removal, open bile duct incision stone removal and choledochoscopy stone removal. Postoperative cholagogic symptomatic treatment.

Primary focal lesions can be treated by bile duct exploration and stone removal, plastic surgery for bile duct stenosis, liver lobe/segment resection, hepatojejunostomy and other operations are also feasible.

However, extensive surgical treatment of intrahepatic bile duct stones is difficult. The main treatment is symptomatic treatment of cholangitis and cholangiectasia, such as liver failure in the late stage of cholestatic cirrhosis. Liver transplantation is feasible.

At present, there are some interventional treatments, such as PTCD+ choledochoscope and ERCP+ choledochoscope, but I only see foreign reports, and the specific details are unknown. It is estimated that the operation may be difficult and the application is limited.
