Is the likelihood of malignant transformation of intrahepatic bile duct stones high?
Intrahepatic bile duct stones have a relatively low probability of becoming cancerous. Patients with intrahepatic bile duct stones may develop acute cholangitis, presenting with symptoms like severe pain in the upper right abdomen, nausea, vomiting, jaundice, and systemic infectious symptoms such as chills and high fever, but generally, these stones do not become cancerous. When patients with intrahepatic bile duct stones exhibit significant symptoms, it is important to take them seriously and perform timely surgical treatment to achieve a radical cure. The main surgical approach is laparoscopic salpingotomy for stone removal, which can lead to better treatment outcomes. Additionally, dietary adjustments should include avoiding spicy and irritating foods to reduce inflammatory stimuli and better prevent exacerbation of the condition.


Surgical treatment methods for intrahepatic bile duct stones
Asymptomatic intrahepatic bile duct stones do not require treatment; regular follow-up examinations are recommended. Surgical treatment should be considered for those with recurring clinical symptoms. The principle of surgical treatment is to remove the stones as much as possible, identify and address bile duct strictures and obstructions, remove infected areas and the sites of stones to restore and establish unobstructed bile drainage, and prevent recurrence of the stones. Surgical methods include choledochotomy for stone removal, bilioenteric anastomosis, and hepatectomy.


Intrahepatic bile duct stones B-ultrasound manifestations
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.


Can intrahepatic bile duct stones be shattered?
Asymptomatic intrahepatic bile duct stones generally do not require treatment. Currently, most hepatobiliary surgeons believe that if patients undergo shock wave lithotripsy, the stones may migrate to the extrahepatic bile duct, forming common bile duct stones, and the patient will experience obvious abdominal pain, jaundice, and other symptoms, causing great trouble. Therefore, they oppose extracorporeal shock wave treatment for intrahepatic bile duct stones and suggest regular follow-up with ultrasound or CT, adopting more reasonable methods for treatment.
