Abstract
Choledochal cyst of the common bile duct is usually considered to be large cystic dilatation that extends from the wall of the common bile duct. Choledochal cyst is a very rare cond.ition in adult, These cysts are commonly distinctive in childran under the age of ten. Even in this age group they are considered rare. The classicajl triad of a choledochal cyst inclule pain, jaundice and a palpable right upper quadrant mass. This triad was found in only 21~63% and the most common finding is jaundice. Diagnoais of choledochal cyst usually is made during laparotomy, In nonjaundiced patients, oral cholangiogram and/or intravenous cholangiogram may yield the diagnosis. In jaundiced patiente where the diagnosis may be more difficult to make, one may consider doing ERCP and/or percutaneous transhepatic cholangiogram. The percutaneous transhepatic cholangiogram seems to be very helpful in diagnosing jaundiced patients. It is being used more and more in recent years but this method is not without complication. With advent of ERCP, visualization of the biliary tree has become a simple procedure when performed by expert endoscopists. To our knowlege, no previous case of choledochal cyst diagnosed by ERCP has been reported. yet in our country This paper reports 4 cases of choledochal cyst diagnosed by ERCP.
