Question & Answer

The Procedure

Q: What does the procedure involve?

The surgeon makes three small incisions and runs a tube with a tiny camera on the end to the surgery site. This gives clear visualization of the surgical field and allows entrance through the other ports. This also allows him to cut the enlarged outer layers of the pyloric muscle to relieve the blockage, leaving the inside lining of the pylorus intact. The surgery is typically performed with the child receiving general anesthesia.


Q: How many incisions are made?

Three tiny incisions are made in the abdomen.

Hospital Stay

Q: How long will my baby stay in the hospital?

In most cases, babies are hospitalized for one to two days to ensure that normal feedings can resume.

Recovery Time

Q: What is the recovery time?

Most babies recover within a couple of days.


Q: How soon before my baby can resume breastfeeding or drinking formula?

As soon as the baby wakes up from anesthesia, the nursing staff begins small feedings until the baby can resume a normal feeding schedule. This normally takes 24 to 48 hours. Some babies will continue to vomit a small amount until the stomach is fully healed. This is normal.
