Overview
Pyloric stenosis occurs in 1 of every 200-300 live births and it is four times more common in males.it is rare in Asians, and it is 2 to 3 times more common in Caucasian compared to African American babies.In one study the prevalence of congenital hypertrophic pyloric stenosis in Donetsk region in the course of 11 years (1989-1999) was 0.73:1000 or 1:1370 newborn infants annual with range of 0.54 to 1.01:1000.[1] Studies show the mortality rate of pyloric stenosis is very low and usually results from delays in diagnosis that causes sever dehydration and shock.
Epidemiology and Demographics
Incidence
The incidence of infantile pyloric stenosis is approximately 400 per 100,000 individuals worldwide.
Gender
Pyloric stenosis is four times more common in males.
Race
Pyloric stenosis is rare in Asians, and it is 2 to 3 times more common in Caucasian compared to African American babies.
Prevalence
In one study the prevalence of congenital hypertrophic pyloric stenosis in Donetsk region in the course of 11 years (1989-1999) was 0.73:1000 or 1:1370 newborn infants annual with range of 0.54 to 1.01:1000.[1]
Case-fatality rate/Mortality rate
Studies show the mortality rate of pyloric stenosis is very low and usually results from delays in diagnosis that causes sever dehydration and shock.
