Antral webs and diaphragms are considered a rare cause of gastric outlet obstruction in infants and children. A radiographic diagnosis of antral web was made in 28 children during a 26-mo period. Nonbilious, often projectile vomiting was the predominant presenting symptom in 24 infants who were less than 6 mo of age. The older children complained of pain, vomiting, fullness after eating, and eructation. The characteristic radiologic finding was a wire-like transverse septum 1-2 cm proximal to the pylorus. Poor antral filling was an important early clue in the radiographic search for the webs. Pyloroplasty was performed in 20 patients, frequently after failure of medical management of symptoms. Coexistent congenital abnormalities were present in 28% of patients. A search for environmental and familial factors has failed to elucidate any teratogenic influences in this population.
