Pyloric Stenosis (Pediatric)

What is pyloric stenosis?

Pyloric stenosis affects infants and is named for the pylorus muscle, a valve between the stomach and small intestine. The pylorus holds food in the stomach until it’s ready for the next step of digestion in the small intestine. Pyloric stenosis occurs when the pyloric muscle  thickens and blocks the passage of food into the small intestine.
