Hypertrophic pyloric stenosis (EHP) is a common surgical pathology in children. Despite being a common condition, its etiology is not yet clearly known. The clinical presentation corresponds to milky, explosive and nonbilious threw up, and in some cases palpable olive in the abdomen or peristaltic waves after being fed. While surgical management of this condition requires the intervention of child surgeon, the initial suspicion includes the general physician and pediatrician. This article presents a review of the available literature on the subject.
