title: Pyloric diaphragm, antral web, congenital antral membrane--a surgery rarity?
abstract: Three cases of pyloric diaphragm in elderly patients are reported. The finding of these patients within a 2-year period (1976-8) suggests that the condition is not as rare as previously thought. Diagnosis was achieved endoscopically and the condition managed surgically. While there has been controversy in the past over whether the disorder is acquired or congenital, the histological evidence of the cases presented here tends to suggest that it is a late presentation of a congenital abnormality.
