BACKGROUND/AIMS Extrahepatic biliary atresia (EHBA) is the most important cause of neonatal cholestasis. The validity of different diagnostic methods in the diagnosis of EHBA in developed countries has been presented elsewhere, but data from developing countries with low national incomes are scarce. The aim of this study was to investigate the relative accuracy and roles of abdominal ultrasonog...

Biliary atresia (BA) is a cholangiodestructive disease affecting biliary tract, which ultimately leads to cirrhosis, liver failure and death if not treated. The incidence is higher in Asian countries than in Europe. Up to 10% of cases have other congenital anomalies, such as polysplenia, asplenia, situs inversus, absence of inferior vena cava and pre-duodenal portal vein, for which we have coin...

Bile duct damage is present in virtually all cholangiopathies, which share the biliary epithelial cells (i.e. cholangiocytes) as a common pathogenic target. Cholangiocyte cell death largely occurs through the process of apoptosis. In this review, we will summarize the mechanisms through which biliary damage occurs in a variety of animal and in vitro models, such as extrahepatic cholestasis indu...

To determine whether portal lymphadenopathy in primary biliary cirrhosis is caused by deposition of lipofuscin pigment in sinus histiocytes and to compare primary biliary cirrhosis with other liver diseases a retrospective study on a consecutive series of 169 livers obtained at transplantation was carried out. There were grouped into eight diagnostic categories: primary biliary cirrhosis (n = 5...

Biliary atresia (BA) is characterized by the progressive fibrosclerosing obliteration of the extrahepatic biliary system during the first few weeks of life. Despite early diagnosis and prompt surgical intervention, the disease progresses to cirrhosis in many patients. The current theory for the pathogenesis of BA proposes that during the perinatal period, a still unknown exogenous factor meets ...

background: biliary atresia is a 100% fatal disorder without any treatment in infants as a leading cause of cirrhosis and kasai operation, as the only operative choice, which plays a crucial role in increasing their rate of survival. nonetheless, many patients end up with liver transplantation in the future owing to various inevitable hepatic and biliary problems which do remain after the kasai...

BACKGROUND/PURPOSE Kasai portoenterostomy is recommended as the primary initial therapy for extrahepatic biliary atresia if the procedure can be performed within 10 to 12 weeks of life. The optimal management for infants with delayed presentation of biliary atresia remains controversial. The purpose of this study was to determine the success rate and outcome for patients who underwent a "late" ...
