Overview
The symptoms of pyloric stenosis usually develop in the first days of life, and start with projectile vomiting. If left untreated, infants with mild infantile pyloric stenosis can develop severe electrolyte imbalances include hypokalemia , hypochloremia, and metabolic alkalosis.In rare cases of untreated pyloric stenosis, patients may develop significant problems on the cognition, receptive language, fine motor, and gross motor skills compared to the normal infants due to long term malnutrition. Complications of infantile pyloric stenosis before surgery include vomiting and failure to gain weight in newborn period. Prognosis is generally excellent and surgery usually provides complete relief of symptoms. Infants usually tolerate small, frequent feedings several hours after surgery
Natural History, Complications, and Prognosis
Natural History
- The symptoms of pyloric stenosis usually develop in the first days of life, and start with projectile vomiting.
- If left untreated, infants with mild infantile pyloric stenosis can develop severe electrolyte imbalances include hypokalemia , hypochloremia, and metabolic alkalosis.[1]
- In rare cases of untreated pyloric stenosis, patients may develop significant problems on the cognition, receptive language, fine motor, and gross motor skills compared to the normal infants due to long term malnutrition.[2]
Complications
- Complications of infantile pyloric stenosis before surgery include:[1]
Prognosis
- Prognosis is generally excellent and surgery usually provides complete relief of symptoms. Infants usually tolerate small, frequent feedings several hours after surgery.[6]
- Up to 80% of patients continue to regurgitate even after surgical correction.[6]
