What do I need to know about a pyloromyotomy?

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).

How do I prepare my baby for surgery?

Your baby's surgeon will talk to you about how to prepare your baby for surgery. He or she may tell you not to feed your baby after midnight on the day of his or her surgery.

What will happen during surgery?

Your baby's surgeon will make small incisions in your baby's abdomen. He or she may make an incision in your baby's belly button. The surgeon will cut the thick, tight pylorus muscle and spread it apart so food can pass through. He or she will close the incision with stitches or medical tape.

What will happen after surgery?

Your baby will be taken to a room to rest until he or she is fully awake. Healthcare providers will monitor your baby closely for any problems. Once your baby's healthcare provider says it is okay, your baby will be able to go home or be taken to his or her hospital room. Your baby may have a tube in his or her nose that goes down to the stomach. This may stay in place for the first 2 or 3 feedings. Your baby may vomit during the first 2 or 3 days after surgery.

What are the risks of surgery?

Your baby may bleed more than expected or get an infection. He or she could develop pneumonia. Your baby's stomach, intestines, or other nearby organs may be damaged. The pylorus muscle could grow thick again and block your baby's intestines. Your baby may need surgery again.
