The duodenum is described as the most common site of intestinal obstruction, classically presenting with bilious vomiting. Of the various categories described, congenital duodenal webs are reported as a rare cause of duodenal obstruction. The clinical features may vary depending on the size and location of the duodenal web. We are reporting 5 pediatric patients with delayed presentation of congenital intrinsic (type 1) duodenal obstruction. All patients presented with recurrent non-bilious vomiting and were misdiagnosed as gastroenteritis in other centers. The diagnosis was confirmed with upper gastrointestinal tract contrast studies. The patients were managed successfully with surgical intervention.
