How is choledochal cyst to return a responsibility?

summary

Choledochal cyst is a congenital cystic dilatation of extrahepatic bile duct and / or intrahepatic bile duct. Due to the different degree of involvement of common bile duct in various choledochal cysts and the new understanding of epithelial markers, the latest term of common bile duct malformation is common bile duct malformation. Today let me tell you something about choledochal cyst?.

How is choledochal cyst to return a responsibility?

First, common bile duct malformation is more common in Asian population, which is considered as a precancerous lesion. 2.5-26% of them develop into gallbladder cancer, cholangiocarcinoma and other malignant tumors. The incidence of common bile duct malformation in women is 3-4 times higher than that in men.

Second, there is a lack of accurate data on the carcinogenic risk of common bile duct malformations. The main purpose of the review is to assess the incidence rate of malignant tumors of common bile duct malformations and identify possible differences between different types of malformations, to investigate the risk of malignant transformation in patients with or without surgery.

Third: choledochojejunostomy can be hepatojejunostomy or hepatoduodenostomy. Hepatoduodenostomy is associated with more complications, such as cholangitis and bile reflux, with malignant transformation. Therefore, Roux-en-Y hepaticojejunostomy after complete cystectomy is the current standard operation.

matters needing attention

The risk of malignant tumor after cyst drainage is 4 times higher than that of cyst resection, especially in patients with type I or IV malformations. When diagnosed with common bile duct malformation, even asymptomatic elderly patients need complete cystectomy.
