Validación de la colonoscopía virtual para el diagnóstico de pólipos de colon en pacientes atendidos en el Hospital José Carrasco Arteaga, Cuenca 2013

Abstract

Objective: To validate the virtual colonoscopy for the diagnosis of polyps in the outpatient Hospital José Carrasco Arteaga. Cuenca 2013.

Methods: The study included 128 patients with indication for conventional colonoscopy rated by the specialist and forwarded to performing virtual colonoscopy. All patients both studies were performed under the same preparation. Sensitivity, specificity, positive and negative predictive values and likelihood ratios were obtained.

Results: Mean age was 59.66 years old. The prevalence of polyps in the study population was 18.8% sensitivity of virtual colonoscopy for diagnosis of polyps 6 to 9 mm was 90% (CI : 59.6 - 98.2 ) and specificity of 97.5% (CI: 92.8 - 99.1) and for polyps ≥ 10 mm , the sensitivity was 87.5% (CI : 52.9 % -97.8%) and specificity of 99.2% (CI: 95.4 % -99.9%).

Conclusions: Virtual colonoscopy showed high sensitivity and specificity for the diagnosis of colon polyps ≥ 6mm.
