What effect does cystic dilatation of fetal common bile duct have?

summary

Congenital cystic dilatation of common bile duct is a congenital disease. When the fetus in the development process, due to the congenital bile duct wall is weak, bile duct has varying degrees of obstruction, so that the pressure in the common bile duct increased, gradually expanded to form a cyst. It can occur in any segment of the bile duct, up to the liver and down to the duodenum. What effect does cystic dilatation of fetal common bile duct have? Let's talk about it

What effect does cystic dilatation of fetal common bile duct have?

Bile duct dilation, recurrent biliary tract infection, each attack will cause damage to the liver. Abnormal pancreaticobiliary junction can lead to many serious problems, such as recurrent pancreatitis. The cyst ruptured and perforated.

It is not accompanied by hepatic fibrosis and portal hypertension, but in later reports, 2 / 3 cases are accompanied by congenital hepatic fibrosis, and are often accompanied by various renal diseases, such as polycystic kidney disease, late cases complicated with cirrhosis and portal hypertension. According to Sherlock classification, it can be divided into four categories: congenital hepatic fibrosis, congenital intrahepatic bile duct dilatation, congenital choledochectasis and congenital hepatic cyst.

There may be one or more lesions in the hepatobiliary system at the same time. This disease is characterized by intrahepatic bile duct dilatation and cholestasis, which lead to bile duct inflammation and stones. However, due to the atypical clinical symptoms, it can occur at any age, with recurrent right upper abdominal pain, fever and jaundice. In the onset of liver swelling, after infection control, with the improvement of symptoms, the liver will often shrink faster.

matters needing attention

Total cystectomy, hepaticojejunostomy? Roux * y anastomosis is ideal for resection. It is a complete resection, eliminating bile retention, stone formation and canceration, which is in line with physiology. But for the patients with repeated infection, it is difficult to excise and easy to injure important organs.
