NOGUERA-VALVERDE, Ronald Armando. Hypertrophic pyloric stenosis. Rev Cubana Pediatr [online]. 2009, vol.81, n.3. ISSN 0034-7531.

Hypertrophic pyloric stenosis is the more frequent cause of surgery in infants under 6 months only surmountable by the hernioplasties. Still the exact cause of stenosis has been not determined, but some theories have been developed related to neurohormonal unbalance or from neuroendocrine mediators in control of pyloric sphincter tone, in gastrine production, and stomach motility. Although at present time its final treatment is surgical, some researchers are reconsidering the pharmacologic approach for treatment of this problem, and other choosing by laparoscopic approach. Clinical diagnosis is still a primary care physician criterion or the pediatrician who as a first resort receive the patients. Differential diagnoses and initial approach for patient stabilization, must to be into account.
