Intrahepatic bile duct stones show typical sonographic changes on ultrasound, appearing as punctate or mass-like strong echoes within the liver, accompanied by acoustic shadows. These strong echoes are distributed along the intrahepatic bile ducts. The bile duct proximal to the stone may exhibit varying degrees of dilation, and the dilated intrahepatic bile duct, along with the accompanying portal vein, forms a parallel tube sign. Around the strong echoes of the stones, a narrow anechoic region can be seen encircling them, and the stones generally do not move with changes in body position. Intrahepatic bile duct stones can also cause thickening of hepatic parenchyma echoes and internal echo heterogeneity.

Multiple intrahepatic bile duct stones

Multiple intrahepatic bile duct stones are a description used in imaging studies such as ultrasound and CT, meaning there are multiple stones within the intrahepatic bile ducts. Particularly in cases where there is recurrent upper right abdominal pain, the appearance of jaundice, chills, and high fever, it is important to pay attention and consider early surgical treatment. The main surgical approach is laparoscopic choledocholithotomy, which can completely treat the condition by removing the stones. Additionally, for patients with intrahepatic bile duct stones, it is also important to avoid spicy and irritating foods in their diet to reduce inflammatory irritation and better promote recovery from the condition. The diet should primarily consist of light meals, and eating fresh vegetables and fruits can better facilitate relief from the condition.

How is intrahepatic bile duct stones treated?

Intrahepatic bile duct stones refer to stones located in the branches of the bile duct above the junction of the left and right hepatic ducts. Surgical treatment is currently the main method of treatment. Treatment should be based on the number and distribution of stones within the bile ducts, the location and extent of hepatic and biliary strictures, pathological changes in the liver, the state of liver function, and the patient's overall symptoms. Appropriate surgical approaches should be adopted, including hepatectomy, high position bile ductotomy for stone removal, transhepatic choledochotomy for stone removal, biliary-intestinal internal drainage, liver transplantation, etc.

If intrahepatic bile duct stones are present without obvious symptoms, no special treatment is needed at this time. It is advisable to regularly re-examine with ultrasound and dynamically observe any changes in size. Of course, diet should avoid spicy and irritant foods, mainly light foods, and consume more fresh vegetables and fruits to reduce inflammatory stimulation and better control the progression of the disease. If there are significant symptoms, there will be obvious pain in the upper right abdomen, and possibly nausea, vomiting, and other gastrointestinal symptoms. Therefore, the treatment should involve early surgical intervention, as surgery is the only way to achieve a cure. The main surgical method is laparoscopic choledochotomy for stone removal.

What medicine should be taken for intrahepatic bile duct stones?

The treatment of intrahepatic bile duct stones currently does not have specific medications. Traditional Chinese medicine treatments primarily focus on clearing the liver and facilitating bile flow, and have certain clinical effects. Western medicine often uses deoxycholic acid, ursodeoxycholic acid, and chenodeoxycholic acid, which can somewhat prevent the formation of bile duct stones. It is also recommended that patients change poor lifestyle habits, adjust their life rhythms, and eat three meals a day at regular times, especially breakfast. Specific medications should be used under the guidance of a doctor.
