Pyloric stenosis

Pyloric stenosis

Location of pylorus in baby's abdomen, with detail of narrowed pylorus (stenosis) before and after surgery

The pylorus is the connection 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 his or her feedings.

To treat pyloric stenosis, a surgeon widens the channel between the stomach and the intestine. Pyloric stenosis does not usually occur again after a baby has been treated.
