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.
Pyloric stenosis may be a serious condition. Pyloroplasty is often necessary to treat it.
An incision will be made in the upper part of your abdomen. The pylorus will be exposed. Your doctor will cut through the pyloric muscle. The sphincter will be sewn back together in a way that will make the opening wider. The abdominal muscles will be sewn back together. The skin will be closed with stitches or staples.
If your pyloroplasty is done because you have an ulcer, other procedures may be done at the same time.
