What to Expect

Prior to Procedure

Make sure your child does not eat or drink anything before the surgery. Follow the specific directions given by your doctor.


General anesthesia will be used. Your child will be asleep.

Description of Procedure

The anesthesia will be given. When your child is asleep, an incision will be made in the abdomen. A cut will be made in the muscle of the pylorus. The pylorus will then be sewn back together in a wider shape.
The abdominal muscles will be sewn back together. The skin will be closed with stitches or staples.

Immediately After Procedure

After the surgery, your child will be monitored for about 1-2 hours.

How Long Will It Take?

The surgery will take about 1-2 hours.

How Much Will It Hurt?

Anesthesia prevents pain during surgery. Your child will be given medication to relieve pain or soreness during recovery.

Average Hospital Stay

The usual length of stay is 1-3 days. The doctor may choose to keep your child longer if there are complications.

Post-procedure Care

At the Hospital
A normal diet will be gradually introduced during the hospital stay. Before your child goes home, you will be taught how to take care of the surgical incision. Ask the doctor about when it is safe for your child to shower, bathe, or soak in water.
Preventing Infection
During your child's stay, the hospital staff will also take steps to reduce the chance of infection, such as:
  • Washing their hands
  • Wearing gloves or masks
  • Keeping your child's incisions covered
There are also steps you can take to reduce your child's chance of infection, such as:
  • Washing both you and your child's hands often, and reminding visitors and healthcare providers to do the same
  • Reminding your child's healthcare providers to wear gloves or masks
  • Not allowing others to touch your child's incision
