Duodenal web most commonly presents with a history of vomiting and failure to thrive in the early infancy period. This study reports on a child who had an initial presentation of feeding intolerance and rare nonbilious emesis. The unusual presentation of food refusal directed the investigation to an upper endoscopy to look for evidence of gastrointestinal mucosal disease such as gastroesophageal reflux disease, peptic ulcer disease, Helicobacter pylori infection, and food allergy including celiac disease. The finding of duodenal web with a central aperture was unexpected but explains the mild degree of her gastrointestinal symptoms.
