title: Congenital (prepyloric) antral membrane: prenatal diagnosis and treatment.
abstract: Congenital antral membrane is a rare cause of gastric outlet obstruction. Symptoms can be seen in any age group, depending on the degree of obstruction caused. Treatment options are pyloroplasty with incision or excision, endoscopic dilatation or resection, and medical management. The diagnosis can be suggested from prenatal examinations, and simple surgical dilatation without pyloroplasty can be successful in managing this condition.
