--- Objective: To determine the diagnostic value of virtual colonoscopy in the detection of colorectal polyps at the National Hospital Guillermo Almenara Irigoyen. Design: Observational, descriptive, retrospective and cross-sectional study. Institution: National Hospital Guillermo Almenara Irigoyen, Lima, Peru. Materials: Medical Records. Interventions: study of medical records of patients with a sample population, which no probabilistic for not meeting the inclusion criteria were a total of 50 medical records, of which 29 were male and 21 female which within a range of ages, from 50– 80 years. The sample was obtained by reviewing medical records each of which met the inclusion criteria, they presented a report of the virtual colonoscopy and conventional colonoscopy between January 2013 - august 2014. Main outcome measures: Sensitivity, specificity, positive and negative predictive value of virtual colonoscopy. Results: With the data collected, the diagnostic value of virtual colonoscopy for evaluation of colorectal polyps was calculated. virtual colonoscopy sensitivity is 90,0% (95% CI 59,6% to 98.2%) and a specificity of 97,5% (95% CI 92,8% to 99,1%) with a positive predictive value of 75,0% (95% CI, 46,8% to 91.1%) and a negative predictive value of 99.1% (95% CI 95,3% to 99,8%) for the diagnosis of colorectal polyps. Conclusions: virtual colonoscopy is a good method to determine whether or not the patient has colorectal polyps. Keywords: colorectal polyps, virtual colonoscopy and conventional colonoscopy.
