Congenital duodenal obstruction: causes and imaging approach.
Bilious emesis is a common cause for evaluation in pediatric radiology departments. There are several causes of congenital duodenal obstruction, most of which require elective surgical correction, but the potential of malrotation with midgut volvulus demands prompt imaging evaluation. We review the various causes of congenital duodenal obstruction with an emphasis on the approach to imaging evaluation and diagnosis.
