Surgery is needed to treat pyloric stenosis. The procedure (pyloromyotomy) is often scheduled on the same day as the diagnosis. If your baby is dehydrated or has an electrolyte imbalance, he or she will have fluid replacement before surgery.
In pyloromyotomy, the surgeon cuts only through the outside layer of the thickened pylorus muscle, allowing the inner lining to bulge out. This opens a channel for food to pass through to the small intestine.
Pyloromyotomy is often done using minimally invasive surgery. A slender viewing instrument (laparoscope) is inserted through a small incision near the baby's navel. Recovery from a laparoscopic procedure is usually quicker than recovery from traditional surgery, and the procedure leaves a smaller scar.
- Your baby might be given intravenous fluids for a few hours or until he or she can eat. You can probably start feeding your baby again within 12 to 24 hours.
- Your baby might want to feed more often.
- Some vomiting may continue for a few days after surgery.
Potential complications from pyloric stenosis surgery include bleeding and infection. However, complications aren't common, and the results of surgery are generally excellent.
