[Congenital obstruction of the gastric antrum: description of a case].

On an average of 100,000 of livebirths congenital obstructive gastric syndromes range from 1 to 3 cases. The syndrome of the congenital antral membrane represents 5% of the total reported cases. It is mostly located 1 to 3 centimeters above the pylorus-duodenal connection and it may occur both in infants and toddlers. In very young patients it might be difficult to differentiate an hypertrophic stenosis of pylorus from a pyloric spasm. In older babies the obstacle to food passage may be moderate and the pathology may not be evident or it can be treated with simple medial therapy. This report presents the case of a 15 months old female with congenital antral membrane.
