[Biliary atresia: a condition requiring urgent diagnosis and treatment]

Area of Science:

• Pediatric Gastroenterology
• Neonatal Medicine
• Surgical Innovation

Context:

• Prolonged neonatal jaundice necessitates comprehensive evaluation to identify underlying causes.
• Neonatal cholestasis (NC) presents a diagnostic challenge, with biliary atresia (BA) being a leading etiology requiring urgent intervention.
• Timely management of NC is critical to prevent severe liver damage and long-term complications.

Purpose:

• To emphasize the urgency of investigating neonatal jaundice exceeding two weeks.
• To highlight the diagnostic pathway for neonatal cholestasis, including stool color examination and bilirubin levels.
• To underscore the critical importance of early biliary atresia diagnosis and surgical timing.

Summary:

• Neonatal jaundice persisting beyond two weeks warrants immediate investigation, starting with stool examination and serum bilirubin tests.
• Confirmation of neonatal cholestasis (NC) mandates Vitamin K administration and referral to specialized centers; biliary atresia (BA) is the primary cause.
• Early diagnosis and surgical intervention for BA, despite normal ultrasounds, significantly improve outcomes, reducing the need for liver transplantation.

Impact:

• Early detection and treatment of BA can prevent progression to biliary cirrhosis and reduce the incidence of liver transplantation in infants and children.
• Improved diagnostic strategies and timely surgical interventions enhance the quality of life for children diagnosed with BA.
• Advances in managing BA contribute to better long-term survival rates, with over 90% of affected children living with a near-normal quality of life.
