Dr Surya Kumar
OBJECTIVESOBJECTIVES
 To know when cholestatic liver disease should be
excluded in the diagnosis of an infant who has jaundice.
 How to evaluate a neonate with conjugated
hyperbilirubinemia.
 Know the therapeutic management of neonates with
cholestasis.
 Understand the differential diagnosis for neonatal
cholestasis.
DEFINITIONSDEFINITIONS
NASPGHAN Definition :
Prolonged conjugated hyperbilirubinemia that
occurs in the newborn period with conjugated
bilirubin concentration >1 mg% if the total
bilirubin <5.0mg% or >20% of the total
bilirubin if the total bilirubin >5.0mg%.
(Moyer et al J PEDIATR GASTROENTEROL NUTR 2004;39:115)
IAP Definition:
Neonatal cholestasis is defined as conjugated
hyperbilirubinemia > 1.5-2 mg% in a newborn/
infant with passage of high coloured urine with
or without acholic stools.

prior to 8 weeks-old.
Bile flow re-established in less than 20% if
performed after 12 weeks-old
KASAI PROCEDUREKASAI PROCEDURE
Success of the operation is dependent on the
presence and size of ductal remnants, the
extent of the intrahepatic disease, and the

 Paracentesis
◦ Thrombocytopenia managed with platelet infusions
when clinically indicated
LIVER TRANSPLANTATIONLIVER TRANSPLANTATION
Biliary atresia is the most common indication
for transplant and may be the initial treatment
when detected late or may be used as a salvage
procedure for a failed Kasai.
Used early in cases of tyrosinemia.
Cost: In excess of 100,000 $
Only few centres in india
Liver transplantationLiver transplantation
Indications:
1)Decompensated liver disease(ascites and/or
encephelopathy) .
2)Failed portoenterostomy.
• 1-year survival rate- 85-90%
• 5-8 year survival rate- 75-80%
• 1/3 to 1/2patients are of Biliary Atresia.(Whitington et al SEMIN LIVER
DIS1994;14:303-317)
PrognosisPrognosis
Biliary Atresia:
• Age(< 8 wks): the single most important
determinant in successful management of BA.
• Of pts. Undergoing Kasai’s procedure,80%
jaundice free if done before 60 days, as against
25-35% of infants operated later on.(Mieli –Vergani et al. LANCET 1989;1:421-423)
Neonatal Hepatitis:
• No indicators to predict prognosis.
Long term outcomeLong term outcome
Biliary Atresia:
Mean survival in untreated pts. :19 mths(Hays et al. SURGERY 1963;54:373-375)
3-year survival : <10% (Karrer et al J PEDIATR SURG 1990;25:1076-1080)
Neonatal Hepatitis:
Upto 60% of pts.with idiopathis NH recover
completely without any specific therapy.
Upto 10% die acutely of bleeding manifetstations
or fulminant hepatic failure.
 30 % progress to liver cirrhosis and death due to
CLD.
Key messagesKey messages
Refer early to specialised centres.
Congenital infection is the commonest cause of
cholestatic jaundice in infants.
Percutaneous liver biopsy is safe and most
useful for diagnosis.
Surgery for BA and choledochal cyst should be
done before 2 months of age.
