ABSTRACT Objective: To determine clinical and epidemiological characteristics of hypertrophic pyloric stenosis in a hospital in Lima, Peru. Materials and Methods: A descriptive and retrospective study encompassing years 2013 to 2019 was performed in the Pediatric Surgery Service of San Bartolome Teaching Mother and Child Hospital.

The average surgical correction time was 51.39 minutes, and the average hospital stay was 6.35 days, major complications occurred in 13.6% of all children, and the mortality rate was 3.4%.
