Choledochoceles refer to a specific type of choledochal cyst (type III under the Todani classification system). In this type, there is dilatation of the intramural portion of the distal common bile duct within the duodenal wall. Its precise etiology is not clear . Patients are usually adolescents and may present with a recurrent crisis of right upper quadrant pain, hyperamylasemia, or jaundice.

Malignant transformation of a choledochocele occurs very rarely.

When a choledochocele is small and symptomatic, it may be treated with an endoscopic sphincterotomy. Larger cysts are often removed by a surgical cystoduodenostomy.
