Recurrent duodenal atresia: a case report.

BACKGROUND: Duodenal atresia is a rare disorder occurring in 1 in 10,000 live births. Duodenal atresia is associated with trisomy 21: 5-15% of trisomy 21 cases have duodenal atresia and 30% of duodenal atresia cases are associated with trisomy 21. Some cases of duodenal atresia may be recurrent.

CASE: Two siblings were born with duodenal atresia but no other anomalies. The father of the siblings also had isolated congenital duodenal atresia.

CONCLUSION: Recurrent duodenal atresia should be considered when the condition is discovered prenatally. The etiology may be autosomal dominant inheritance, as with Feingold syndrome, or autosomal recessive inheritance.
