The cost of biliary drainage ranges from about $5,000 to $50,000, but the price varies from hospital to hospital because of the different procedures and equipment used. 1. Biliary drainage is mainly operated through laparoscopy, i.e. laparoscopic choledochotomy for stone removal and T-tube retention. The bile duct is opened and the stones are removed so that bile can be discharged smoothly and the symptoms of obstructive jaundice with bile duct stones can be improved. The cost is about 20,000~30,000 dollars. 2. In addition, bile duct drainage surgery is also treated by interventional methods, commonly used methods mainly include percutaneous transhepatic puncture bile duct external drainage and ERCP placement of biliary stent for internal drainage. The cost of the puncture is about $5,000, and the cost of the biliary stenting ranges from $20,000 to $50,000, depending on the material of the stent. The price of bile duct drainage varies due to the different equipment used and the different pricing of each hospital, so the price is somewhat different, usually ranging from 5,000 to 50,000 yuan. It is recommended to consult the hepatobiliary surgery department of a regular hospital for details.
