How to treat congenital choledochal cyst?

There are many internal organs inside the human body, and each of them is indispensable. Even a very small organ like the gallbladder is vital to the human body because the gallbladder is an important organ that secretes digestive enzymes. The digestive enzymes it secretes can easily break down fat, allowing the stomach and intestines to more easily absorb the nutrients in the fat. However, the gallbladder is also a site prone to disease, which often causes great pain to patients. For example, congenital common bile duct cyst is an extremely painful symptom that can cause inflammation of the gallbladder and induce gallbladder disease. Let’s take a look at how to treat congenital common bile duct cyst.

Congenital choledochal cyst, also known as common bile duct dilatation, is a biliary tract malformation characterized by common bile duct cyst or fusiform dilatation, with or without intrahepatic bile duct dilatation. It is the most common congenital abnormality and the most common disease of congenital hepatobiliary cysts. Other lesions may exist at the same time. It is generally believed that the incidence rate in Asian population is significantly higher than that in Europe and the United States, and is mostly discovered in infancy and childhood. The incidence rate in women is higher than that in men, accounting for 60% to 80% of the total incidence rate.

If this disease is not treated surgically, the patient will often die from repeated infections, biliary cirrhosis, common bile duct perforation or cancer. Therefore, surgery should be performed promptly once the patient is diagnosed.

1. Treatment principles for congenital choledochal cysts

(1) The main purpose of surgery is to restore bile drainage into the intestine to avoid ascending cholangitis.

(2) Resection of the dilated common bile duct to prevent future canceration.

(3) To prevent anastomotic stenosis in the future.

2. Surgical methods for congenital choledochal cysts

(1) Cyst resection, Roux-Y anastomosis of the common hepatic duct and jejunum, and anti-reflux valvuloplasty.

(2) Cyst resection, jejunal interposition to replace the bile duct, and anti-reflux giant flap surgery.

(3) Cyst duodenostomy and cystectomy with common hepatic duct duodenostomy. This method is rarely used nowadays because it is difficult to prevent reflux infection and anastomotic stenosis.
