The aim of this paper is to describe the mechanism

clinical manifestation

diagnosis and surgical management of congenital choledochal cyst. [WT5”BX] Methods.[WT5”BZ] From 1984 to 1997

56 cases of congenital choledochal cyst were reviewed. Among them

8 patients were male

48 patients were female

the age ranges from 12 to 50 years old with an average of 26 3. [WT5”BX] Results.[WT5”BZ]The main clinical manifestation includes jaundice

abdominal pain and abdominal mass. All of them were confirmed by ultrasonography

while 39 cases were performed ERCP and PTC with the same diagnosis. Fifty one patients were performed cystectomy and hepatojejunostomy

two cases were performed cystjejunostomy because of diffused angioma and severe hemorrhage respectively

external drainage was performed in one case with emergent cholangitis

the other two cases were reported malignancy through biopsy and operation was abandoned. [WT5”BX] Conclusions. [WT5”BZ]Ultrasound diagnostics is essential to accurately diagnose the cyst

preoperative ERCP is helpful for differentiating pancreatic duct from bile duct

while MRCP is a reliable method; cystectomy and cholangiojejunostomy is recommended

laparoscopic procedure is becoming more and more accepted.
