Nonvisualization of the gallbladder during the second trimester of pregnancy should prompt concern for biliary atresia. A normal-sized gallbladder with irregular and crenelated wall associated with a cyst of the extrahepatic tract should raise concern for cystic biliary atresia.

Case 1. The elder of two sibs, this boy was born on May 21, 1965 to unrelated healthy parents aged 29 (mother) and 30 years (father). Birthweight was 2820 g.; delivery was by forceps. His mother had 'influenza' between the fifth and sixth months of the pregnancy which had been otherwise normal. There was no previous foetal loss. Four generations of the family, comprising, in addition to the par...

introduction: early differentiation of biliary atresia from neonatal hepatitis is of utmost importance, since on time surgery of biliary atresia significantly improves the outcome. hepatobiliary scintigraphy is an integral part of diagnosis work-up of these patients; however its specificity for diagnosis of biliary atresia is suboptimal. in this study we evaluated the value of ursodeoxycholic a...

Biliary atresia is the most common cause of pathologic jaundice in young infants and results from the obstruction of the extrahepatic bile ducts by an inflammatory and fibro-obliterative process. Although the pathogenesis of the disease is multifactorial, recent patient- and animal-based studies began deciphering the molecular pathways involved in biliary injury and duct obstruction. Using larg...

OBJECTIVES To define the sensitivity, specificity and accuracy of the ultrasound triangular cord sign and hepatic histopathology, in isolation or in combination, for diagnostic differentiation between biliary atresia and intrahepatic cholestasis. METHODS This was a retrospective study carried out between January 1990 and December 2004. Fifty-one cases of biliary atresia and 45 of intrahepatic...

OBJECTIVE To assess the feasibility of screening for cholestatic hepatobiliary disease and extrahepatic biliary atresia by using tandem mass spectrometry to measure conjugated bile acids in dried blood spots obtained from newborn infants at 7-10 days of age for the Guthrie test. SETTING Three tertiary referral clinics and regional neonatal screening laboratories. DESIGN Unused blood spots f...

Biliary atresia is a neonatal obstructive cholangiopathy characterized by a fibrosclerosing obliteration of the extrahepatic bile duct that uniquely presents in the first months of life (1). The condition occurs in approximately 1 in 8,000 to 1 in 15,000 live births and accounts for 30% of all cases of cholestasis in young infants. Biliary atresia is the most frequent cause of chronic end-stage...

Three infants who presented with clinical features of neonatal cholestasis and clinically suspected to have biliary atresia were found on imaging studies and surgery to have extrahepatic bile duct atresia in association with choledochal cyst. All patients were treated by bilio-enteric bypass procedure. Post operatively jaundice cleared in only two patients. The prognosis of this association dep...
