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 enlargerment 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, a mass, such as cancer, or inflammatory diseases.
