Abstract
|
|
|
The puspose of this study was to know the confluental anatomy of the intrahepatic biliary duct and the occurrence of the stone according to each segmental biliary duct in the recurrent pyogenic cholangitis.
We classified 139 of T-tube cholangiography(AP and oblique view the confluence of intrahepatic biliary tracts. Prevalence, size and number of the stones were evaluated according to each hepatic segmental duct.
The confluence of the right and left main hepatic ducts was the most popular type(57.6%). The right main hepatic duct was abscent in 38.8% and the left main hepatic duct was abscent in 2.9%. The occurrence of the stones was high in left lateral
segmental duct(50.4%) and then right posterior segmental duct(32.4%), right anterior semental duct(23.0%) and left medial segmental duct(12.2%) in descending order. There were no stones in caudate lobe. There was no difference in the size
according
to
each segmental duct. The number of the stones was high in right posteior duct(17.5) and left lateral duct(17.1). But there was no statistical meaning in size and number.
The incidence of the each confluental type was similar to other previous study. There was no stones in caudate lobe. The longer and wider of the duct, the more statis of the bile, the more stones occured. There was no size difference. The number
of
the
stones is high in right posterior and left lateral duct, but there was no statistical meaning.
