Pyloric stenosis

Congenital hypertrophic pyloric stenosis; Hypertrophic pyloric stenosis; Gastric outlet obstruction

Treatment for pyloric stenosis involves surgery (called a pyloromyotomy) to split the overdeveloped muscles.

Balloon dilation does not work as well as surgery, but may be considered for infants when the risk of general anesthesia is high.

The patient will be given fluids through a vein, usually before surgery.

Surgery usually provides complete relief of symptoms. The infant can usually tolerate small, frequent feedings several hours after surgery.

• Vomiting after surgery -- this is very common and generally improves with time
• Failure to gain weight in the newborn period
• Risks associated with any surgery, which include:
  • Bleeding
  • Infection

Call your health care provider if your baby has symptoms of this condition.
