Prevalencia de cálculos en vías biliares en pacientes de 35 a 85 años diagnosticada por colangiopancreatografía por resonancia magnética en el Instituto de Diagnóstico por Imagen, Cuenca- Ecuador enero 2021- diciembre 2022

Abstract

Stones form from bile components that have precipitated in crystal forms. Frequency of stones has had a significant increase in advanced age and in females. Currently, MRI is a first-line method with high sensitivity (93%) and specificity (96%). Objective: To determine the prevalence of bile duct stones in patients aged 35 to 85 years diagnosed by magnetic resonance cholangiopancreatography at the Institute of Diagnostic Imaging, in Cuenca, Ecuador, from January 2021 to December 2022. Method: Descriptive, retrospective and crosssectional study. Data was analyzed and tabulated according to the study variables. Results: Out of 326 patients, 281 cases tested positive: The prevalence of bile duct stones in patients aged 35 to 85 years diagnosed by magnetic resonance cholangiopancreatography at the Institute of Diagnostic Imaging in Cuenca, Ecuador, from January 2021 to December 2022, was 86.2%. Female sex prevailed (64.4%) and patients between 65 and 74 years old were the most affected (40.2%). Stones in the gallbladder reached a percentage of 39.5% and absence of anatomical variations reached 92.9%. Conclusion: There is a high prevalence of bile duct stones, which mainly affect females between 65 and 74 years of age, and their morphological location is more frequent in the gallbladder, featuring also absence of anatomical variations. Similar findings are reported in other studies.
