What is Pyloromyotomy?

Pediatric pyloromyotomy is a surgical procedure performed on infants to treat a condition known as pyloric stenosis. In pyloric stenosis, the pylorus muscle, which controls the passage of food from the stomach to the small intestine, becomes abnormally thickened. This thickening prevents food from moving into the intestines, leading to symptoms like vomiting, dehydration, and weight loss. Pyloromyotomy involves making an incision in the thickened pyloric muscle, allowing food to pass through more easily.

How to diagnose Pyloromyotomy? When to consult a doctor?

Diagnosis of pyloric stenosis involves the following steps: Medical History and Physical Examination, Imaging Tests & Blood Tests.

You should consult a doctor if:

  • Frequent, Forceful Vomiting: If the infant vomits forcefully (often described as projectile vomiting) after feeding, it may indicate a blockage due to pyloric stenosis.
  • Dehydration: Signs include decreased urine output, dry mouth, crying without tears, and sunken eyes or soft spot on the head (fontanel).
  • Poor Weight Gain or Weight Loss: If your infant isn't gaining weight or is losing weight, it could be due to an inability to retain food.
  • Hunger After Vomiting: Babies with pyloric stenosis are often very hungry and want to feed right after vomiting.
