Atresia duodenal - Overview

Definición:

Es una afección en la cual la primera parte del intestino delgado (el duodeno) no se ha desarrollado adecuadamente. No está abierto y no puede permitir el paso de los contenidos del estómago.

Causas:

No se conoce la causa de la atresia duodenal, pero se cree que resulta de problemas durante el desarrollo de un embrión en el cual el duodeno normalmente no cambia de una estructura sólida a una estructura similar a un tubo.

La atresia duodenal se observa en más de 1 de cada 10.000 nacidos vivos y aproximadamente del 20 al 30% de los bebés que la padecen sufren el síndrome de Down. Esta enfermedad a menudo está asociada con otras anomalías congénitas.
