title: Delayed diagnosis of duodenal obstruction in Down syndrome.
abstract: Four children with Down syndrome (trisomy 21) came to medical attention in late childhood with symptoms of obstruction of the upper gastrointestinal tract. Each patient had radiographic evaluation. The combination of Down syndrome, retained foreign material in the stomach or proximal duodenum, and obstruction resulted in the diagnosis of congenital duodenal stenosis in each patient.
