Pyloric stenosis

Pylorus between stomach and small intestine, with detail showing narrowed pylorus sphincter muscle (stenosis) before surgery and widened pylorus after surgery.

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.
