Congenital choledochal cyst has been generally considered as a rare disease, but the number of the
cases reported in the literature increased gradually now a days on the part of general surgery. So
many congenital anomalies of the extra-hepatic biliary system have been reported, but the most
important of clinical significant are only two types. There are the choledochal cyst and atresia of
the bile duct.
Only ten cases confirmed of congenital abscence of the intra-hepatic portion of the biliary tree have
been reported, on the contrary congenital abscence of extra-hepatic duct are more frequently seen.
And comparatively most frequent is the choledochal cyst.
So many theory the cause of congenital choledochal cyst has been described but generally considered
to be a certain abnormalities in development of the biliary apparatus such as difficulties with the
drarinage of bile products related to a structure of the biliary bile duct, angulation of the common
duct and atresia of some portion of the ductal system which mant cause localized dilatation of the
common duct. Choledochal cyst are more common in female (4:1) and which usually reveals sy
mptoms at sometimes during the first three decades of life.
The triad characteristic clinical symptoms are upper abdominal pain, the development of the
palpable mass of fullness in the ipper abdomen and obstructive jaundice. The Asiatic race seem to
be rather easily affected and especially in the Japanese race. About two-third of all of the case
in the world reported literature occured in the Japanese race.
In our country, Lee, Chung, Kim and many other surgeons also habe been reported recently for
choledochal cyst. The present study undertakes to reported 9 cases from 1966 up to date in Chung
Nam medical Center and to bring literature briefly.
The treatment of the choice is surgical procedure, complete resection of the cyst if it is possible
or well defined. But it is preferable to avoid direct resection of unless one has clear visualization
of all the biliary structure, and consist of conneting the cyst the duodenum or jejunum, choledo
choduodenostomy or a Roux-Y choledochoenterostomy is safer and effective.
Postoperative complication, ascending cholangitis may occur but this case may be controlled the
additional use of antibiotics and a stenosis of the stoma of the Anastomosis may prevent to operated
by well trained surgeon.
All our patient were treated with choledochoduodenostomy and the prognosis were excellent.
