Pyloric is the opining from the stomach to the first part of small intestine
( duodenum)
non-invasive and does not use radiation, which is a significant advantage in children.
commonly available with relatively low cost
allows a dynamic study with direct observation of the pyloric canal morphology and behavior.
Hypertrophic pyloric stenosis (HPS) is a result of both hyperplasia and hypotrophy of circular muscle fiber, with elongation and thickening
forceful, projectile vomiting
Dehydration
weight loss
Babies with pyloric stenosis may seem to be hungry all the time
