Pyloroplasty
Alternate Names : Pyloric Stenosis Repair, Pyloromyotomy
Definition
Pyloroplasty is surgery performed to relieve pyloric stenosis, a narrowing of the pyloric channel at the outlet of the stomach that causes projectile and nonbilious vomiting. This surgery allows the stomach contents to empty into the duodenum (small intestine) more readily.
Overview & Description
While the patient is under general anesthesia (unconscious and pain-free), the abdomen is cleaned and draped. The surgeon makes a small incision into the abdomen and then makes a cut into the pyloric muscle (stomach outlet) down to the mucosa, which releases the restriction that has kept it closed. No tissue is removed and the stomach lining is not opened.
The pyloric muscle returns to normal size over time.
