Pyloric stenosis is a condition that is caused by a narrowing of the stomach outlet by thickened muscle. As a result, milk and fluids cannot empty from the stomach into the small bowel.
This is a common condition that affects infants usually between 3-8 weeks of age. It often presents with projectile vomiting of milk.
Pyloric stenosis is managed with surgery to relieve the obstruction. The vomiting may result in significant disturbance of your child's fluid and electrolyte (salt) balances and they will need to receive fluid with a drip to correct this before surgery. Surgery is carried out as a laparoscopic (key-hole) or open procedure and involves cutting of the muscle to relieve the obstruction.
Generally, babies with pyloric stenosis recovery quickly after the operation and are able to start feeding within 24 hours.
