Overview
Infantile pyloric stenosis is a condition that causes severe vomiting in the first few months of life. There is narrowing (stenosis) of the opening from the stomach to the intestines, due to spasm and hypertrophy of the muscle surrounding this opening (the pylorus). It is uncertain whether there is a real congenital narrowing or whether there is a functional hypertrophy of the muscle which develops in the first few weeks of life.
Pyloric stenosis also occurs in adults where the cause is usually a narrowed pylorus due to scarring from chronic peptic ulceration. This is a completely different condition from the infantile form.
Historical Perspective
In 1717, Dr.patrick Blair reported autopsy findings of pyloric stenosis for first time and in 1912 Conrad Ramstedt observed an uneventful recovery in a patient followinf pyloroplasty that remains standard procedure for pyloric stenosis today.
