STENOSIS OF THE PYLORUS

There are two types of stenosis of the pylorus in infancy. One is a stenosis due to a muscular spasm of the pylorus called a pylorospasm. The other is a stenosis due to a hypertrophy of the pylorus known as hypertrophic stenosis of the pylorus. It is possible for both conditions to be present at the same time. The stenosis may be congenital and is usually called stenosis of infancy. It is considered a serious condition and the mortality is very high.

This incoördination is characterized by constipation, persistent wasting, projectile vomiting, and a marked visible tumor.
