Overview
The incidence of infantile pyloric stenosis is approximately 400 per 100,000 individuals worldwide and it is four times more common in males.It usually affects individuals of the Caucasian race. Asians individuals are less likely to develop Infantile pyloric stenosis. The prevalence of infantile pyloric stenosis in the course of 11 years (1989-1999) was approximately 7.3 per 100,000 individuals in one study. Studies showed 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.
The cumulative incidence of infantile pyloric stenosis per 100000 is approximately 240 in White, 180 in Hispanic, 70 in Black, and 60 in Asian infants.
Prevalence
The prevalence of infantile pyloric stenosis in the course of 11 years (1989-1999) was approximately 7.3 per 100,000 individuals in one study.[1]
Case-fatality rate/Mortality rate
The mortality rate of pyloric stenosis is very low and usually results from delays in diagnosis that causes sever dehydration and shock.
Gender
Males are more commonly affected by infantile pyloric stenosis than females.The male to female ratio is approximately 4 to 1.
Race
Infantile pyloric stenosis usually affects individuals of the Caucasian race. Asians individuals are less likely to develop Infantile pyloric stenosis.
Age
Infantile pyloric stenosis commonly affects infants.
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.
