Onfalocele - Overview

Definición:

Es un defecto congénito en el cual se presenta protrusión de los intestinos u otros órganos abdominales del bebé a través del ombligo. En los bebés con un onfalocele, los intestinos sólo están cubiertos por una capa de tejido delgada y se pueden observar fácilmente.

Un onfalocele es un tipo de hernia. Hernia significa "ruptura".

Causas:

Un onfalocele se desarrolla a medida que el bebé crece dentro del útero de la madre. Los músculos en la pared abdominal (anillo umbilical) no se cierran apropiadamente y, como resultado, el intestino permanece por fuera del cordón umbilical.

Aproximadamente del 25 al 40% de los bebés con onfalocele tienen otros defectos congénitos, entre los cuales pueden estar problemas genéticos (anomalías cromosómicas), hernia diafragmática congénita y defectos cardíacos.
