MOJENA MEDINA, Daylén Julia et al. Clinic-epidemiological characteristics in patients with hypertrophic pyloricstenosis. 15-year study in a tertiary center. Multimed [online]. 2021, vol.25, n.3  Epub 12-Maio-2021. ISSN 1028-4818.

Hypertrophic pyloric stenosis is characterized by hypertrophy and hyperplasia of the muscle fibers and narrowing of the pyloric canal, which causes non-bilious vomiting, giving rise to one of the most common causes of surgical treatment in the newborn stage. A retrospective descriptive study was carried out in 119 patients with a diagnosis of hypertrophic pyloric stenosis at the “William Soler” University Pediatric Hospital from 2000 to 2015. 70.6% of the children were between three and five weeks old and 83.2% a weight at diagnosis between 2500 g to 4500 g. Vomiting was present in all patients, alterations in body weight in 79.8% and hydroelectrolyte and basic acid imbalances in 53.8%. Male sex, white racial appearance, being first-born, and artificial or mixed breastfeeding were significant prevalent risk factors associated with the disease (p <0.05). Hypertrophic pyloric stenosis was most frequently diagnosed at the 4th week of life and in children weighing between 3000 and 4500 g. The weight variations denote the importance of following the weight curve in these patients.
