Acquired gastric outlet obstruction during infancy and childhood: a report of five unusual cases.

Infantile hypertrophic pyloric stenosis is a common, specific, and well-understood entity in the pediatric age group. Prepyloric webs and diaphragms are the other rare causes of gastric outlet obstruction followed by still rarer causes, eg, pyloric stenosis secondary to acid peptic disease. The present report describes a newer, nonspecific, clinical condition of pyloric obstruction in five patients of varying age who responded very well to Henieke-Mikulicz' pyloroplasty. The authors have suggested some modifications in the classification of gastric outlet obstruction in children to include these patients.
