Resumen
Las diarreas congénitas son trastornos hereditarios que causan diarrea grave persistente en los lactantes, que a menudo llevan a falla intestinal con desenlace fatal si su diagnóstico no es temprano. Estos trastornos generalmente afectan el epitelio intestinal o sus mecanismos de transporte, ya sea afectando las enzimas digestivas, el sistema inmune o los canales de intercambio de electrolitos. El diagnóstico definitivo de estas enfermedades generalmente incluye estudios genéticos, sin embargo, la biopsia intestinal juega un papel fundamental en la orientación al mismo. Esta revisión presenta un resumen de estas entidades, con énfasis en las más frecuentes a nivel mundial.
