Bile duct stones include intrahepatic bile duct stones and extrahepatic bile duct stones. If the size of bile duct stones is relatively small, below 0.2 cm, and there is no symptom, then no treatment is needed, regular follow-up can be observed. However, if the size is 0.5 cm or more, and there are symptoms, then timely treatment is needed, and the main treatment methods are medication and surgery. Intrahepatic bile duct stones are stones in the bile ducts of the left and right hepatic ducts above the confluence. Surgery is the most common and effective treatment for bile duct stones at this stage. There are three main types of surgery: the first is to remove the stones from the intrahepatic bile duct completely; the second is to remove part of the liver when the stones grow in the liver and the surgery cannot remove all the stones. The third type is to anastomose the bile duct and jejunum to form a large drainage port to allow the stones in the liver to drain smoothly into the intestine and thus out of the body. People with bile duct stones must be treated promptly for specific treatment options, follow the clinician’s instructions, pay more attention to diet, and refrain from drinking and smoking in general.
