Estenosis hipertrófica congénita del píloro.

Abstract

An analysis is made of 18 cases with congenital pyloric stenosis, attended at the Hospital General de México S.S.A. The discussion is focused toward: age, sex, clinical, laboratory data and radiological features. Literature to this respect is reviewed finding historical data, surgical techniques employed and etiological hypothesis. We conclude, that every physician who attends children must keep in mind that infants under four months of age, with a history of vomiting immediately after feeding, without biliar contents, progressive in frequency and intensity, accompanied by pyloric stenosis must be suspected. The clinical examination must be directed to finding peristalic waves and pyloric tumor. Pyloromyotomy is the treatment in all cases. The prognosis should be favorable if the diagnosis and correction are properly and promptly made.
