A pilot study of the value of a stool color card as a diagnostic tool for extrahepatic biliary atresia at a single tertiary referral center in a low/middle income country.

Background And Study Aims: Biliary atresia (BA) is a major cause of hepatic failure and consequent liver transplantation in pediatrics. If BA is not diagnosed early and the proper surgical intervention is not performed before the age of 3 months, the survival of the affected infant is significantly reduced. In 1994, a stool color card (SCC) for early detection of BA was developed and used in Japan, a country where the parents' socioeconomic and education levels are high.
