What is a Type 2 choledochal cyst?
Type II choledochal cysts (see image below) appear as an isolated true diverticulum protruding from the wall of the common bile duct. The cyst may be joined to the common bile duct by a narrow stalk.
What is Type 4 choledochal cyst?
Background/purpose: Type IV-A choledochal cysts are characterized by congenital cystic dilatation of the biliary tree extending to involve the intrahepatic biliary channels also. A single-center experience of the management of type IV-A choledochal cysts is presented.
What are the different types of choledochal cysts?
Choledochal cysts are typically diagnosed as one of several types:
- Type I: Cyst of the bile duct.
- Type II: Pouching or sac on the bile duct.
- Type III: Cyst within the wall of the duodenum (where the duct connects to the liver) or pancreas.
- Type IV: A Type I cyst that extends into the liver along the bile ducts.
What is Type 3 choledochal cyst?
Type III Cyst Choledochoceles are the true cyst of the distal common bile duct protruding into duodenum. Patients present with biliary colic, cholangitis, or pancreatitis. Until recently transduodenal cyst excision with or without sphincterotomy was the treatment of choice [44].
What is a Type 1 choledochal cyst?
Type 1 — a cyst of the extrahepatic bile duct, accounting for up to 90% of all choledochal cysts. Type 2 — an abnormal pouch or sac opening from the duct. Type 3 — a cyst inside the wall of the duodenum. Type 4 — cysts on both the intrahepatic and extrahepatic bile ducts.
What is the most common type of choledochal cyst?
Type I cysts (see image below) are the most common and represent 80-90% of choledochal cysts. They consist of saccular or fusiform dilatations of the common bile duct, which involve either a segment of the duct or the entire duct. They do not involve the intrahepatic bile ducts.
When is Hepaticojejunostomy done?
Precise sutured hepaticojejunostomy usually can be carried out after exposure of the left hepatic duct beneath the quadrate lobe by lowering of the hilar plate or within the umbilical fissure by using the ligamentum teres approach (Blumgart & Kelley, 1984).
What is Hepaticojejunostomy surgery?
A hepaticojejunostomy is the surgical creation of a communication between the hepatic duct and the jejunum; a choledochojejunostomy is the surgical creation of a communication between the common bile duct (CBD) and the jejunum.
What is Hepaticojejunostomy with Roux-en-Y?
What is hepaticojejunostomy? A hepaticojejunostomy, or Roux-en-Y procedure, bypasses the bile duct to allow digestive juices to drain from the liver directly into the small intestine. The hepatic duct is the tubular channel that carries bile from the liver to the small intestine to aid digestion.
Why Hepaticojejunostomy is performed?
Roux-en-Y hepaticojejunostomy (RYHJ) is currently considered as the definitive treatment for iatrogenic bile duct injuries [1]. It is a common operation, not only to bypass extrahepatic biliary obstructions, but also to establish biliary-enteric continuity after resections for benign and malignant diseases.
