Treatment of multiple stones in the intrahepatic bile ducts: MRI of the upper abdomen, also known as MRCP water imaging of the biliary tract, is required to see the location of the patient’s multiple stones in the intrahepatic bile ducts, as well as the number of multiple stones. If the stones are relatively small and located in the tertiary or quaternary bile ducts, it is recommended that the patient actively consider taking Ursodeoxycholic acid capsules for active lithotripsy treatment. After two months, the upper abdominal ultrasound or MRI should be reviewed to see if the gallbladder stones and bile duct stones have decreased in size. If there is a reduction, the patient should continue to take the medication. If there is further increase in size, consider other treatments. In addition, for patients with a large number of intrahepatic bile duct stones that have caused obstructive jaundice, active consideration may be given to hepatic lobectomy of the stones and removal of the stones from the intrahepatic bile duct via the hepatic duct. After aggressive surgical treatment, the patient should take Eusebio for about 2-3 months to further prevent the occurrence of intrahepatic bile duct stones. It is important to eat less or no cholesterol-rich foods, as the consumption of cholesterol-rich foods can further increase the risk of gallbladder stones and intrahepatic bile duct stones.
