Choledochal cyst
Choledochal Cyst
A Choledochal Cyst (pronounced: koh-lee-DOH-kal sist) is a congenital condition characterized by the formation of a cyst or dilation in the bile ducts. The term "Choledochal" is derived from the Greek words "chole" meaning bile and "dochus" meaning duct, while "cyst" is derived from the Greek word "kystis" meaning bladder or sac.
Types
There are five types of Choledochal Cysts, classified according to the Todani classification system:
- Type I: Cystic dilation of the common bile duct
- Type II: Diverticulum of the common bile duct
- Type III: Choledochocele, a dilation of the intraduodenal portion of the common bile duct
- Type IV: Multiple cysts in the intrahepatic and extrahepatic bile ducts
- Type V: Multiple cysts in the intrahepatic bile ducts, also known as Caroli's disease
Symptoms
Symptoms of a Choledochal Cyst may include jaundice, abdominal pain, nausea, and vomiting. In some cases, the cyst may lead to pancreatitis or cholangitis.
Diagnosis
Diagnosis of a Choledochal Cyst typically involves imaging studies such as ultrasound, computed tomography (CT) scan, or magnetic resonance cholangiopancreatography (MRCP).
Treatment
Treatment for a Choledochal Cyst usually involves surgical removal of the cyst, followed by reconstruction of the bile ducts. This is typically done through a procedure known as a Roux-en-Y hepaticojejunostomy.
