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.
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.
Gallbladder stones incidence rate in men and women
Understanding the gender differences in the prevalence of various diseases has important practical significance for the occurrence, development, and prevention of diseases. Research in this area has gradually gained attention from health prevention workers and provides a scientific basis for health prevention efforts. Various clinical studies indicate that the prevalence of gallstones is significantly higher in women than in men, with an incidence ratio of about 3:1 in the affected population. With economic development, people's lifestyles and dietary structures have undergone tremendous changes, leading to an increasing trend in the incidence of gallstones. In China, approximately 8%-11% of patients suffer from gallstones, predominantly obese women around forty years old, often referred to by the three Fs: fat, forty, female.
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.
"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.
Do you need to cut the liver for intrahepatic bile duct stones?
The treatment of intrahepatic bile duct stones primarily requires surgery to remove the stones, relieve obstruction, and correct deformities. Generally, there is no need to remove the liver. However, if the liver has a tumor, or if intrahepatic bile duct stones are accompanied by liver fibrosis or even liver atrophy, partial liver lobe resection can be considered. For asymptomatic patients with intrahepatic bile duct stones, temporary observation and follow-up are feasible.
What to do if you have cholecystitis?
Cholecystitis usually occurs in people with gallstones or gallbladder polyps. Patients with cholecystitis generally experience discomfort and bloating pain in the upper right abdomen. Cholecystitis is an inflammation of the inner wall of the gallbladder, which can cause abdominal pain in mild cases and lead to bile stasis and suppurative cholecystitis in severe cases. The first step in treating cholecystitis is to actively use antibiotics. Those with cholecystitis should actively use antimicrobial and anti-inflammatory drugs. It is also important to maintain a light diet and avoid consuming too many greasy foods. To prevent recurrence, it is generally recommended that patients take oral anti-inflammatory and bile-promoting tablets after cholecystitis symptoms are controlled. These medications can play a preventive role in patients with acute and chronic cholecystitis.
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.
