  • What to Expect

  • Reasons for Procedure


    The pylorus sphincter can become narrowed, usually from an enlargerment of the muscle. The condition is called
    pyloric stenosis. It can cause severe symptoms such as nausea, vomiting, and
    dehydration. Narrowing of the pylorus can be the result of scarring from ulcers, a hiatal hernia, a mass, such as cancer, or inflammatory diseases.

    Pyloric stenosis may be a serious condition. Pyloroplasty is often necessary to treat it.

  • Possible Complications

    Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:

    • Bleeding
    • Infection
    • Damage to intestines
    • Hernia formation at the incision site

    • Chronic
      diarrhea

    Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications, such as:

    • Smoking
    • Drinking
    • Chronic diseases, such as diabetes or
      obesity
