title: The increasing incidence of infantile hypertrophic pyloric stenosis.
abstract: Several reports have suggested that there is an increasing incidence of infantile hypertrophic pyloric stenosis (IHPS). We examined the incidence of IHPS in a stable population in the West of Ireland over a ten year period (1981-1990). During the 10 years of the study the number of live births per year did not alter significantly. The incidence of IHPS increased significantly from 0.87/1000 live births in 1981 to 5.10/1000 in 1990 (p < 0.001, Student's test), peaking in 1989 at 6.8/1000. There was no statistical correlation between the increasing incidence and feeding habits, birth rank, family history or gender distribution. The reason(s) for this increase remain unclear.
