What is the cause of biliary obstruction

summary

Choledocholithiasis with obstructive jaundice, is actually caused by choledocholithiasis jaundice, in our daily life this disease is too common, this kind of jaundice is also known as cholestatic jaundice, its fundamental cause is intrahepatic and extrahepatic bile duct obstruction, in which bile duct mechanical obstruction or bile juice excretion disorder is the main cause of cholestatic jaundice. Intrahepatic obstructive cholestasis is mostly caused by intrahepatic bile duct sediment like stones, clonorchiasis, cancer thrombus, etc.; intrahepatic cholestasis is mostly due to bile excretion disorders, but no mechanical obstruction, such as capillary type viral hepatitis, drug-induced cholestasis. Let's take a look at the following.

What is the cause of biliary obstruction

First, intrahepatic cholestasis can also be seen in primary biliary cirrhosis, gestational idiopathic jaundice, etc.; extrahepatic obstructive cholestasis is more common in common bile duct stones, cholangiocarcinoma, Ascaris lumbricoides, biliary inflammatory edema, biliary stricture, pancreatic head cancer, etc. Let's understand its pathogenesis.

Second: its pathogenesis is: due to biliary obstruction, the pressure of the bile duct above obstruction increases, gradually leading to the rupture of small bile duct, the conjugated bilirubin in bile flows back into the blood, so that the concentration of conjugated bilirubin in the blood increases, and the hepatointestinal circulation is blocked, so that fecal bilirubin in feces is reduced, but urine bilirubin is increased.

Third: the main manifestations of jaundice are dark and dark, yellowish green or greenish brown, accompanied by itching skin, bradycardia, deepening urine color, white clay stool color, chills, high fever, right upper abdominal pain and other symptoms of biliary obstruction. Laboratory tests showed an increase in blood bilirubin.

matters needing attention
