The pylorus is a muscle in the baby's  stomach that connects to the small intestine.

It helps food move between  the stomach and the intestine.

With pyloric stenosis, the  pylorus gets thick and swollen.

Food can get stuck in the stomach. That's  why your baby may vomit after feeding.

Pyloric stenosis repair—sometimes  called pyloromyotomy—is a surgery that makes a small cut in the pylorus  to widen the opening into the intestine.

Your baby's surgery will be done either  by laparoscopic surgery or open surgery.

Laparoscopic surgery is done through several  small cuts—called incisions—in the area.

Open surgery is done through one  slightly larger cut in the area.

Before the surgery, your baby will get medicine  so they won't feel anything during the procedure.

The doctor will make a cut in the pylorus to create more space so that  food can leave the stomach.

The surgery may be stressful for you. But knowing  what to expect and how to prepare can help.

Recovery and healing take time.

But if you have any questions or  concerns, you can always call your doctor.
