Congenital prepyloric web in a child

A case of a child with an antral mucosal web is presented. The literature concerning these webs in children and adults is reviewed. Several conclusions are reached. First, the etiology of these webs in adults and children is different. Second, webs are not usually considered in a differential diagnosis of gastric outlet obstruction, and the correct diagnosis is often not made even with contrast radiography and endoscopy being employed. Thirdly, it is speculated that division of these webs via the endoscope is quite plausible.
