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.

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.

"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.

Is the incidence of intrahepatic bile duct stones high?

Intrahepatic bile duct stones have a relatively low incidence rate. They are a type of gallstone, and compared to gallbladder stones, their occurrence is less frequent. Patients with intrahepatic bile duct stones often experience concurrent cholangitis, leading to symptoms such as upper abdominal pain, significant nausea, and vomiting, along with other gastrointestinal symptoms. Therefore, for patients with intrahepatic bile duct stones, when significant symptoms occur, not only is the use of antibiotics necessary to treat the infection and control the inflammation, but surgery is also required to achieve therapeutic effects. The primary surgical method is choledochotomy for stone removal, which can lead to better treatment outcomes after the stones are extracted.

What should be noted for intrahepatic bile duct stones?

Patients with intrahepatic bile duct stones should pay attention to the following: First, try to reduce the intake of fats, especially animal fats; second, the formation of a considerable number of intrahepatic bile duct stones is related to high cholesterol levels and metabolic disorders in the body, so it is necessary to limit foods high in cholesterol, such as eggs and the organs of various meat animals; third, food should be prepared by steaming, boiling, or stewing; fourth, increase the supply of fish, lean meats, soy products, and fresh fruits and vegetables.

What are the sequelae of liver resection for intrahepatic bile duct stones?

Patients with intrahepatic bile duct stones do not have significant sequelae after liver resection because the area of the liver removed during the surgery is relatively small, generally not causing significant effects. Furthermore, for patients with intrahepatic bile duct stones, the main treatment involves making an incision in the bile duct to remove the stones, which can completely cure the condition, and patients can typically recover within about seven days after the surgery. Since the procedure is mainly performed using laparoscopy, it has the advantages of smaller incisions, less damage, and faster recovery. Therefore, postoperative recovery is relatively good. At this time, patients can also avoid spicy and irritating foods in their diet to reduce inflammatory irritation, better promoting recovery from the condition. There are no significant sequelae after the resection.
