Atresia biliar - Symptom

Síntomas:

Los recién nacidos con esta afección pueden parecer normales al nacer; sin embargo, la ictericia (una coloración amarillenta de la piel y de las membranas mucosas) se presenta hacia la segunda o tercera semana de vida. El bebé puede aumentar de peso durante el primer mes, pero luego lo pierde, se torna irritable y presenta empeoramiento de la ictericia.

Otros síntomas pueden abarcar:

  • Orina turbia
  • Esplenomegalia
  • Heces flotantes
  • Heces con olor fétido
  • Heces pálidas o de color arcilla
  • Crecimiento lento
  • Poco o ningún aumento de peso

Pruebas y exámenes:

El médico llevará a cabo un examen físico, que incluye palpar el área ventral del paciente. El doctor puede igualmente sentir un agrandamiento del hígado.

Los exámenes para diagnosticar la atresia biliar son, entre otros:

  • Radiografía abdominal
  • Ecografía abdominal
  • Exámenes de sangre para verificar los niveles de bilirrubina total y directa
  • Gammagrafía con ácido iminodiacético hepatobiliar (HIDA), también llamada colescintigrafía, para ayudar a determinar si las vías biliares y la vesícula están funcionando apropiadamente
  • Biopsia del hígado para determinar la gravedad de la cirrosis o para descartar otras causas de ictericia
  • Radiografía de las vías biliares (colangiografía)
