Pyloromyotomy is surgery to widen your baby's pylorus. The pylorus is the opening between your baby's stomach and intestine. He or she may have trouble eating if the opening is too narrow (a condition called stenosis).


Seek care immediately if:

  • Your baby is vomiting and cannot keep any liquids down.
  • Your baby has any of the following signs of dehydration:
    • Dry mouth or cracked lips
    • Fast heartbeat or breathing
    • More irritable or fussy than usual
    • Urinating little or not at all
    • Sunken eyes or fontanels (soft spot on the top of the head)

Call your baby's pediatrician or surgeon if:

  • Your baby has a fever.
  • Your baby vomits more than 2 times in 1 day or vomits more than 2 days in a row.
  • Your baby is irritable and fussy, even after pain medicine.
  • Your baby's surgery area is red, swollen, or draining fluid.
  • You have questions or concerns about your baby's condition or care.


Your baby may need any of the following:

  • Acetaminophen decreases pain and fever. It is available without a doctor's order. Ask how much to give your baby and how often to give it. Follow directions. Read the labels of all other medicines your baby uses to see if they also contain acetaminophen, or ask your baby's doctor or pharmacist. Acetaminophen can cause liver damage if not taken correctly.
  • Do not give aspirin to children under 18 years of age. Your child could develop Reye syndrome if he takes aspirin. Reye syndrome can cause life-threatening brain and liver damage. Check your child's medicine labels for aspirin, salicylates, or oil of wintergreen.
  • Give your child's medicine as directed. Contact your child's healthcare provider if you think the medicine is not working as expected. Tell him or her if your child is allergic to any medicine. Keep a current list of the medicines, vitamins, and herbs your child takes. Include the amounts, and when, how, and why they are taken. Bring the list or the medicines in their containers to follow-up visits. Carry your child's medicine list with you in case of an emergency.

Feed your baby as directed:

Your baby may be able to have his or her usual amount of breast milk or formula.

Care for your baby's surgery area as directed:

Care for your baby's surgery area as directed. Keep your baby's abdomen dry for at least 2 days. Then you may put your baby in a tub bath. Carefully wash the surgery area with soap and water and pat it dry. The medical tape will peel off on its own. Do not pull it off.

Follow up with your baby's pediatrician or surgeon as directed:

Write down your questions so you remember to ask them during your visits.
