Educational Pearls:

  • Pylorus becomes hypertrophied and does not allow food or liquid to pass through to the duodenum
  • Occurs between the ages of 3 weeks to 3 months
  • Classic presentation includes projectile nonbilious vomiting and palpable abdominal mass
  • Ultrasound can visualize/diagnose pyloric stenosis and the treatment is surgical correction
  • Be aware that electrolyte abnormalities and acid/base disturbances may occur
