Perfil epidemiológico de pacientes con colelitiasis diagnosticados por ecografía en el servicio de imagenología del Hospital Básico de Durán en el periodo 2021 – 2024.

Abstract

The most prevalent pathology in the Departmente of General Surgery is cholelithiasis, affecting a significant proportion of the population worldwide, with an anual incidence of 10% to 30%, resulting in approximately 1,000,000 new cases each year. The objective of our study is to determine the epidemiological profile of patients with cholelithiasis diagnosed by ultrasound at the Imaging Service of The Durán Basic Hospital between 2021 and 2024. A population of 283 patients was obtained, adjusted to a 95% confidence level (Z:1.96), a maximun estimation error of 5%, and 50% probability of occurrence. This resulted in a sample of 164 patients for our research study. The results showed a high frequency (57,9%) in the studied population, with a predominance in females and in the 45 -65 age group. Obesity was identified as one of the main associated risk factors, most cases corresponded to uncomplicated cholelithiasis and were managed by laparoscopic treatment, with a low frequency of complications.
