Congenital hypertrophic pyloric stenosis

Congenital hypertrophic pyloric stenosis, an important cause of intractable vomiting in infants is diagnosed clinically and confirmed ultrasonographically. Other useful interventions are plain radiography and barium study. Differential diagnosis includes pylorospasm and gastroesophageal reflux. Management protocol includes correction of dehydration and electrolyte imbalance and either Fredet Ramstedt pyloromyotomy or medical treatment with atropine sulphate. Atropine is initially given intravenously till vomiting is controlled and then orally at double the effective i.v. done for another 3 weeks. Atropine sulphate is generally well tolerated and side effects are few like tachycardia, raised SGPT and hyperthermia. Atropine sulphate is very effective, cheap, safe and perhaps more acceptable treatment option for CHPS.
