Early infantile hypertrophic pyloric stenosis: surgery at 26 hours of age.

A newborn baby with hypertrophic pyloric stenosis on the first day of life is presented with a review of the literature regarding this early age of onset. The average age at onset of symptoms is usually 3.5 weeks. Very rarely symptoms start at birth or are sometimes delayed until 3 months of age or more (20). There are several reports (2, 3, 5, 6, 11, 14, 18, 19) of infants with onset of symptoms and eventual operation within the first day or two of life and indeed with vomiting from birth (2, 3, 5, 6, 11, 14, 18, 19). To our knowledge this case report documents the youngest baby ever operated upon for infantile hypertrophic pyloric stenosis at 26 hours of age.
