This paper has for its object the clearing up of certain etiologic and therapeutic misconceptions which have long been applied to the condition commonly known as pylorospasm. To date, my own observations on this subject have been entirely clinical. They have been reinforced, so to speak, by the physiologic and pharmacologic findings of others.
RELATION BETWEEN "PYLOROSPASM" AND CONGENITAL HYPERTROPHIC PYLORIC STENOSIS
In some of our best textbooks on pediatrics, pylorospasm is considered secondarily in the discussion of congenital hypertrophic pyloric stenosis. The good results of surgery in the latter condition, and the opportunity for study of such cases on the operating table, may well be held responsible for the tendency to regard pylorospasm as a localized phenomenon, strictly confined to the pylorus, and often associated with organic hypertrophy. Such local spasm, plus increasing pyloric induration, has been advanced by many as the reason why infants with hypertrophic pyloric stenosis
