Choledochal Cysts
A choledochal cyst an abnormal enlargement of the bile duct that is a result
of a congenital abnormality of the bile duct. Depending on the location
and type of enlargement, there can be different types of choledochal cysts.
This abnormal bile duct causes poor drainage which creates an infection.
Some patients develop repeated attacks of pancreatitis since the pancreatic
duct may enter into the abnormal bile duct. A vast amount of choledochal
cysts are identified during childhood and present with jaundice from the
decrease in drainage from the bile duct.
The diagnosis of choledochal cysts is not difficult once the condition
is suspected. An ultrasound will show an abnormal bile duct and an
ERCP (Endoscopic Retrograde Cholangiopancreatogram) will demonstrate the abnormal enlargement of the bile duct.
