Situs inversus abdominus in association with congenital duodenal obstruction: a report of two cases and review of the literature.

This report describes two newborns with persistent bile-stained vomiting. Their radiological investigations revealed the existence of situs inversus and duodenal obstruction. In one, the duodenal obstruction was partial, secondary to a duodenal diaphragm with a central aperture, whereas the other child had complete duodenal atresia as well as Fallot's tetralogy.
