After cessation of bile flow, dilatation of extrahepatic and intrahepatic bile ducts
and alteration of portal tracts occur in a few days.
In ERCP, dilatation of common bile duct with multiple filling defects was seen, but gallbladder and intrahepatic bile ducts
were normal (Figure 2).
Loss of intrahepatic bile ducts
or ductopenia is usually designated when bile ducts are absent in at least 50% of portal tracts provided that at least 10 portal tracts are available for assessment.
4) Autoimmune-mediated destruction of intrahepatic bile ducts
eventually leads to bile flow obstruction, hepatic fibrosis, cirrhosis, and eventual liver failure.
Intrahepatic bile duct
adenomas are rare, benign tumors composed of disorganized but mature peribiliary gland acini and tubules.
5] Caroli's disease is characterized by segmental dilatation of the intrahepatic bile ducts
without hepatic fibrosis as compared to Caroli's syndrome, which is defined as ectasia of the intrahepatic bile ducts
with hepatic fibrosis.
If US demonstrates dilated intrahepatic bile ducts
and a hilar tumour is suspected, MRCP is the next investigation of choice, as more accurate non-invasive imaging of the level and extent of the bile duct obstruction is obtained (Fig.
Cholangiocarcinomas arise from the biliary ductal epithelium, most commonly in the bifurcation of the intrahepatic bile ducts
The intrahepatic bile ducts
, CHD, CBD and intrahepatic veins were unremarkable.
Biliary atresia is an inflammatory cholangiopathy of infancy that results in progressive fibrosis and obliteration of extrahepatic and intrahepatic bile ducts
INTRODUCTION: Jacques Carole in 1958 first described a rare disease with multifocal, segmental, saccular dilatation of the large intrahepatic bile ducts
, which causes stagnation of bile formation of biliary sludge and stones.
This protocol applies to carcinomas of the intrahepatic bile ducts
and mixed hepatocellular-cholangiocarcinoma.
