Pyloroplasty is a surgery to correct a narrowing of the pyloric sphincter. The pylorus is a muscular area that forms a channel between the stomach and intestine. Normally, food passes easily from the stomach into the intestine through this sphincter.

The pylorus sphincter can become narrowed, usually from an enlargement of the muscle. The condition is called pyloric stenosis. It can cause severe symptoms such as nausea, vomiting, and dehydration. Narrowing of the pylorus can be the result of scarring from ulcers, a hiatal hernia, inflammatory diseases, or a mass, such as cancer.
Pyloric stenosis may be a serious condition. Pyloroplasty is often necessary to treat it.
