How is node of bile duct inside liver to return a responsibility?
summary
More and more people are troubled by intrahepatic bile duct stones. People are not clear about the causes of intrahepatic bile duct stones, which makes people do not know how to treat intrahepatic bile duct stones. Hepatobiliary tract is an important digestive organ of human body. The bile secreted is mainly to decompose fat, which is conducive to human absorption. If hepatobiliary lesions appear intrahepatic bile duct stone symptoms, it has a great impact on people's health. So let's share what happened to the intrahepatic bile duct node?.
How is node of bile duct inside liver to return a responsibility?
First, intrahepatic bile duct stones refer to the stones distributed in a branch of intrahepatic bile duct, or in the bile duct of a certain region, the left side is more than the right side. According to the different course of disease and pathology, the clinical manifestations of intrahepatic bile duct stones can be various, from the early stage without obvious clinical symptoms limited to the stones in a certain segment of intrahepatic bile duct, In the late stage, it is common in the intrahepatic and extrahepatic bile duct system, and even complicated with biliary cirrhosis, liver atrophy, liver abscess and other advanced cases, so the clinical manifestations are very complex. The main clinical manifestation is acute cholangitis, including triad of biliary obstruction (pain, chills, fever, jaundice) and pentad of severe cholangitis.
Second, the etiology of intrahepatic bile duct stones is related to bacterial infection, parasitic infection and bile retention. Infection is the primary cause of stone formation. The common causes of infection are biliary parasite infection and recurrent cholangitis. Bacteria can be detected in bile culture of almost all patients with hepatolithiasis.
Third: the infection bacteria mainly come from the intestinal tract. The common bacteria are Escherichia coli and anaerobes. The b-glucuronidase produced by Escherichia coli and some anaerobes and the endogenous glucuronidase produced by biliary tract infection can hydrolyze conjugated bilirubin to free bilirubin, and the retention of sedative bile is a necessary condition for the formation of intrahepatic bile duct stones. Only under the condition of bile retention can the components in bile deposit and form stones. Bile retention was caused by inflammatory stricture and biliary malformation; At the distal end of the obstruction, the pressure in the bile duct increases, the bile duct dilates, and the bile flow is slow, which is conducive to the formation of stones. In addition, mucin acid, mucopolysaccharide immunoglobulin and other macromolecular substances in bile, inflammatory exudates, exfoliated epithelial cells, bacteria, parasites, metal ions in bile are involved in the formation of stones.
matters needing attention
In general, the formation of intrahepatic bile duct stones is due to the gallstone formation, but the key lies in the patency of bile drainage. Therefore, we should have regular diet and regular review. B-ultrasound was used to investigate the compensatory dilatation of biliary tract. These may be helpful for your prevention. After partial cholecystectomy, choledocholithiasis is caused by abnormal function of sphincter at the lower end of common bile duct, or some small particles of choledocholithiasis fall into the common bile duct without symptoms, which is only discovered as time goes on. Take it easy. Even if these stones appear, they can be removed through endoscopy as long as they are found early.
