[Duodenal diaphragm in children (two cases)].

Duodenal diaphragm is a rare cause of intestinal obstruction. Two pediatric cases are reported in which vomiting of bile-stained material and distension of the epigastrium were the main clinical signs. Roentgenograms and sonograms were highly suggestive. Duodenal bypass was easy to perform and effective. Nevertheless, it must be kept in mind that associated anomalies are frequent and may be severe.
