Intrahepatic bile duct stones can generally be detected via ultrasound, as they show up as strong echoes due to their solid nature which reflects sound waves back to the surface.

However, the majority of these intrahepatic bile duct stones are asymptomatic. Since they rarely cause dilation of the intrahepatic bile ducts, and as long as the bile ducts do not appear dilated, thickened, or tortuous on the ultrasound, they usually do not have any significant impact. Therefore, most intrahepatic bile duct stones do not require treatment and can be managed through observation.

Symptoms of intrahepatic bile duct stones

Intrahepatic bile duct stones, depending on the duration and pathology, can present with various clinical manifestations. In the early stages, patients generally do not show obvious symptoms, with stones limited to a certain segment within the intrahepatic bile ducts. In later stages, stones can be found throughout the intra- and extrahepatic biliary system, and may even lead to biliary cirrhosis, liver atrophy, and liver abscesses. The clinical manifestations can include: first, pain in the upper abdomen; second, a long history of biliary tract diseases, with patients experiencing chills, fever, and jaundice; third, frequent pain and discomfort in the liver area on the affected side and the lower chest, which can radiate to the shoulder and back, etc.

Are intrahepatic bile duct stones the same as gallstones?

Intrahepatic bile duct stones are a type of gallstone, and patients with intrahepatic bile duct stones often develop cholangitis. Thus, patients may exhibit symptoms such as chills, high fever, jaundice, and significant upper abdominal pain. They might also experience nausea and vomiting. In severe cases, the condition can lead to acute obstructive suppurative cholangitis, septic shock, and even result in death. Therefore, intrahepatic bile duct stones should be taken seriously. If significant symptoms occur, it is advisable to undergo surgery as soon as possible. The surgical method can be a laparoscopic choledochotomy to remove the stones, which can be curative. Gallstones also include gallbladder stones, which are a common type clinically. If symptoms occur, the treatment method is also surgical, involving the removal of the gallbladder to achieve a cure.

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.

Does Jin Qian Cao expel gallstones from the liver's bile ducts?

This method cannot eliminate intrahepatic bile duct stones. The treatment for intrahepatic bile duct stones mainly depends on the symptoms. For patients with intrahepatic bile duct stones who do not have significant symptoms and whose stones are relatively small, no special treatment is required. Avoiding spicy and irritating foods in the diet can reduce inflammatory stimuli and better control the condition. Regular follow-up with ultrasonography is sufficient. However, for patients with larger intrahepatic bile duct stones, acute cholangitis may occur, presenting with significant upper abdominal pain. In such cases, proactive treatment is necessary. The treatment mainly involves surgery, which can significantly improve the prognosis and potentially cure the condition.

"Intrahepatic bile duct stones"

Intrahepatic bile duct stones, as the name implies, are stones located within the bile ducts inside the liver. The biliary tract is divided into extrahepatic and intrahepatic bile ducts. The intrahepatic bile ducts refer to the left and right hepatic ducts and their related branches. The intrahepatic bile ducts evolve from the left and right hepatic ducts into the common hepatic duct, common bile duct, and gallbladder, which are part of what we commonly refer to as the extrahepatic bile ducts. The symptoms of intrahepatic bile duct stones are not as apparent as those of common bile duct stones, but most intrahepatic bile duct stones cause upper abdominal pain in patients; generally, jaundice does not occur.
