Abstract

A 3-year-old boy presented with postprandial vomiting and epigastric pain for 3 wk. Barium meal study suggested hypertrophic pyloric stenosis. Ultrasound of the stomach after water loading revealed an echogenic antral web with an eccentric aperture and distal antral hypertrophy. Subsequent endoscopy confirmed the ultrasound findings. Web resection and antropyloroplasty resulted in excellent recovery. To our knowledge, the barium meal and ultrasound findings of an antral web-associated distal antral hypertrophy and prepyloric stenosis has not previously been described.
