Delayed Diagnosis of Congenital Duodenal Stenosis in a 16-Year-Old Girl.

Duodenal atresia or stenosis are different degrees of the same abnormality. They usually occur at the level of the ampulla of Vater and are thought to be an embryologic defect during the development of the foregut, leading to abnormal recanalization. Complete duodenal atresia is usually symptomatic in the early neonatal period, while partial obstruction (web, stenosis) may have a late presentation and a more challenging diagnosis such as in our case. Gastroptosis is not diagnostic for a particular disease. This rare radiological finding in children may obscure uncommon diagnosis, such as congenital duodenal stenosis, which can present a diagnostic challenge beyond early childhood.
