Introduction:

Hypertrophic pyloric stenosis (HPS) is a condition that is characterized by the obstruction of physiological gastric emptying and is considered a surgically-resolved pathology.

Objective:

To characterize patients with congenital hypertrophy of the pylorus treated at the Regional Hospital of Orinoquía between 2010 and 2020.

Methods:

Observational, descriptive and retrospective study of patients who were admitted at the Orinoquía Regional Hospital between January of 2010 and December of 2020. The patients that were included had a diagnosis of hypertrophic pyloric stenosis identified by the ICD-10 codes.

Results:

A total of patients were included by selection criteria. The average age of participants was 24.3 days old. Most of them were males and 2 patients were overweight at birth. The most common symptom was postprandial emesis in 100%. The diagnosis was made through measurements of pylorus measured with abdominal ultrasound. All the patients performed pyloromyotomy, and only one required a surgical reintervention, however, the mortality was 0.

Conclusions:

Congenital hypertrophy of pylorus is an uncommon pathology, whose cardinal symptom is postprandial emesis. The ideal diagnostic method is an ultrasound study. Despite its complexity, this pathology has a good short and long-term prognosis.
