Epidemiological survey of 6 years' federal health service experience of pyloric stenosis: case report of presentation in a 26-month male.
Congenital hypertrophic pyloric stenosis (CHPS) is primarily a surgical process of the neonate and infant. Diagnosis and treatment of CHPS in a 26-month-old male prompted an inquiry of the military health service database for age of onset, sex, and birth position data. Data were analyzed on 604 cases found in a 71-month time period. The incidence for first-born males was .43 percent, for other than first-born males .34 percent, and for females .091 percent, the peak age being 3 weeks and 1 month old. Children diagnosed at age 6 months and older, as well as adults, were identified. Utilization of the Federal Health Care System data base allowed the study of a large number of patients with a broad spectrum of social, racial, and geographic backgrounds. We feel the study of this data provides a unique understanding of the epidemiology of this entity (CHPS).
