Hypertrophic pyloric stenosis (HPS) is the most common cause of gastric outlet obstruction in infants. It commonly requires surgery. Its incidence is 0.17-4.4 cases per 1,000 live births. The clinical findings of pyloric stenosis typically appear within three to five weeks after birth. Its most important clinical finding is non-bilious projectile vomiting. If its diagnosis is missed in early period, the most common finding is dehydration (with hypochloremic hypokalemic metabolic alkalosis).

Because vomiting is the one of most common symptoms, it may be related to the different etiological factors of vomiting (congenital or genetic causes, NEC, sepsis, nutritional intolerance), blockage of projectile vomiting with gastric drainage by previously inserted indwelling orogastric/nasogastric catheter which prevents development of excessive gastric dilatation. The accurate diagnosis delays with elimination of severe alkalosis and electrolyte disorder and prevention of malnutrition with administered parenteral nutrition. Herein we would like to draw attention the delayed diagnosis of HPS in five neonatal cases who were hospitalized in the neonatal intensive care unit (nicu) for longer periods.
