Páncreas anular - All Information

Definición:

Es un anillo de tejido pancreático que circunda el duodeno (la primera parte del intestino delgado). Normalmente, el páncreas reposa al lado del duodeno, pero no lo rodea.

Causas, incidencia y factores de riesgo:

El páncreas anular es un defecto congénito, lo cual significa que está presente al nacer. Los síntomas ocurren cuando el anillo del páncreas comprime y estrecha el intestino delgado, de manera que el alimento no puede pasar fácilmente o no puede pasar en absoluto.

Los recién nacidos pueden tener síntomas de obstrucción completa del intestino. Sin embargo, hasta la mitad de las personas con esta afección no tienen síntomas hasta la adultez. Igualmente, hay casos que no se detectan debido a que los síntomas son leves.

Las afecciones que pueden estar asociadas con el páncreas anular abarcan:
