Duodenal atresia is typically documented in one third of cases of which condition?

• A. Down syndrome
• B. Cystic fibrosis
• C. Edwards syndrome
• D. Patau syndrome

Answer: (A)

Duodenal atresia is a congenital intestinal obstruction that is notably associated with Down syndrome. In infants with Down syndrome, about one third have a duodenal atresia, making this condition the most common association. This link helps explain why a newborn with Down syndrome may present with vomiting and a distended abdomen, and on imaging may show the classic signs of duodenal atresia. The other listed conditions are not as strongly associated with this specific anomaly.
