CONGENITAL HYPERTROPHIC PYLORIC STENOSIS

Congenital hypertrophic pyloric stenosis (HPS) is a common condition in the neonatal and infancy stage. It predominates in first-born males and, despite advances in the field of pediatric surgery and neonatology, both in research and medical practice, the cause is still not well defined. This disease is characterized by narrowing of the pyloric channel due to muscular hypertrophy of the pylorus that hinders gastric emptying. The clinical manifestations are given by projectile vomiting without bile, poor weight gain or malnutrition, food craving and, in severe cases, dehydration and basic-acid disturbances. The management of this condition must be timely to avoid complications and achieve normal growth and development of the child. There is medical treatment for this condition, but surgical intervention is the treatment of choice.
