Neonatal cholestasis should be considered in every baby in whom jaundi
ce persists after day 10. Biliary atresia is the main cause of neonata
l cholestasis and ifs prognosis is highly dependent on the early age a
t which surgery is performed. Finding the cause of cholestasis before
day 30 is therefore crucial. This relies, in most instances, on simple
clinical, biochemical, radiological and ophthalmologic criteria, the
most important of which is a careful study of the degree and duration
of stool discoloration. (C) 1998 Elsevier, Paris.
