Bile duct stones are a type of bile duct stones. In general, patients with bile duct stones should have a low-fat diet and should not eat fatty foods, such as fried, deep-fried, egg yolk, and fatty meat. It also depends on whether the bile duct stones are intrahepatic or extrahepatic, the size of the stones, and whether there are symptoms. If it is an extrahepatic bile duct stone, early surgery is recommended because stones inside can cause symptoms of cholangitis, which can cause abdominal pain, high fever, chills, and jaundice. The location of the bile duct stones should be clarified as soon as possible, and the treatment should be done according to the location and the symptoms. It is recommended that if the extrahepatic bile duct stones or intrahepatic bile duct stones are large and cause symptoms, timely surgical treatment is needed.
