Abstract

Pyloric atresia is a rare malformation, with an incidence of 1:100,000 live newborns. Male to female ratio is 1/1. Typically, it is an isolated malformation, with a good prognosis, but 20-40% of cases present epidermolysis bullosa, and to a lesser extent, multiple intestinal atresias. We present the case of a pre-term newborn prenatally diagnosed with polyhydramnios, duodenal atresia with "double bubble" sign, and suspected Down's syndrome, who eventually had pyloric atresia.

La atresia pilórica es una malformación rara, presenta una incidencia de 1:100.000 recién nacidos vivos y la ratio hombre/mujer es de 1/1. Generalmente es una malformación aislada, con buen pronóstico, pero entre el 20-40% de los casos se asocia a epidermólisis bullosa y en menor frecuencia a otras atresias intestinales múltiples. Presentamos un caso de recién nacido pretérmino con atresia pilórica con el diagnóstico prenatal de polihidramnios, atresia duodenal con signo de ‘doble burbuja’ y sospecha de síndrome de Down.
