Persistent infant jaundice beyond three weeks requires evaluation for neonatal cholestasis, a condition of impaired bile excretion. Early diagnosis and intervention, especially for biliary atresia, are crucial for infant health outcomes.

Area of Science:

  • Neonatology
  • Pediatric Gastroenterology
  • Hepatology

Background:

  • Neonatal cholestasis is defined as impaired bile excretion leading to bile substance accumulation.
  • Persistent jaundice beyond 2-3 weeks necessitates evaluation for this condition.
  • Differentiating conjugated from unconjugated hyperbilirubinemia is critical for diagnosis.

Purpose of the Study:

  • To outline the evaluation and diagnosis of neonatal cholestasis.
  • To highlight key clinical features and differential diagnoses.
  • To emphasize the importance of timely intervention for specific conditions like biliary atresia.

Main Methods:

  • Evaluation of infants with prolonged jaundice.
  • Fractionated serum bilirubin level assessment.

  • Systematic differential diagnosis approach.

    • Main Results:

    • Conjugated hyperbilirubinemia, pale stools, and dark urine are key indicators.
    • Biliary atresia is a frequent cause requiring early surgical intervention (before 60 days).
    • Premature infants present unique challenges requiring modified evaluation.

    Conclusions:

    • Prompt evaluation of prolonged infant jaundice is essential.
    • A systematic diagnostic approach aids in identifying causes like biliary atresia.
    • Management focuses on supportive care, complication management, and nutritional support.
