Pyloric stenosis
The pylorus is the muscle between the stomach and the first part of the small intestine. Pyloric stenosis is a condition in which a baby's pylorus gradually swells and thickens. This interferes with food entering the intestine and causes the baby to vomit most or all of their feedings.
To treat pyloric stenosis, a surgeon widens the pylorus sphincter muscle.
