What does Choledochocele mean?
A choledochocele is a cystic dilation of the distal common bile duct (CBD). It corresponds to a type 3 choledochal cyst in the classification by Todani et al1 and is extremely rare. 2. The diagnosis is challenging and rarely made before surgery, as the presenting symptoms vary wildly and are nonspecific.
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 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.
How common is choledochal cyst?
Choledochal cysts are rare: one in every 100,000 to 150,000 children in Western countries is born with choledochal cysts. Girls are four times more likely to be affected than boys. The condition is more common in East Asian countries, especially Japan, though researchers do not know why.
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?
Abstract. 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.
How is a choledochal cyst removed?
Choledochal cysts are typically treated surgically, either by an open surgical procedure (using one incision) or laparoscopically, where small incisions and a camera are used to guide the surgeon. Both procedures are performed in the operating room under general anesthesia.
When does a choledochal cyst need surgery?
Factors to be considered when performing surgery on patients with biliary cystic disease include: (1) age, (2) presenting symptoms, (3) cyst type, (4) associated biliary stones, (5) prior biliary surgery, (6) intrahepatic strictures, (7) hepatic atrophy/hypertrophy, (8) biliary cirrhosis, (9) portal hypertension, and ( …
Is choledochal cyst curable?
The treatment of choice for choledochal cysts is complete excision of the cyst with construction of a biliary-enteric anastomosis to restore continuity with the gastrointestinal tract.
What are the subtypes of choledochoceles?
Several subtypes of choledochal cysts have been described, including the choledochocele, which is an abnormal dilatation of the distal common bile duct within the ampulla of Vater. The purpose of this review is to contrast the natural history of choledochoceles and choledochal cysts.
What is a choledochal cyst?
Medical Definition of choledochal. : relating to, being, or occurring in the common bile duct a choledochal cyst.
Are choledochoceles associated with pancreatitis?
Compared with those with choledochal cysts, patients with choledochoceles are more likely to present with pancreatitis and less likely to present with biliary tract symptoms [18,23,25,43]. Among patients with choledochoceles, Sarris and Tsang [40] reported a pancreatitis rate of 38%, as did Masetti and colleagues [17] in a large review.
