Abstract

Aim: To evaluate the performance of endoscopic visualization in the identification of premalignant gastric lesions, with histopathological examination of biopsy samples as a reference test, in Bucaramanga, Colombia. Location: League for the Fight Against Cancer, Bucaramanga, Colombia. Design: Diagnostic technology evaluation with cross-sectional sampling. Measurements: We calculate the sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratio (+), likelihood ratio (-), kappa index and the prevalence rate kappa. Results: A total of 155 patients were studied, with a mean age of 45.43 (14.15) years and an approximate male:female ratio of 2:1. The endoscopic visualization had a sensitivity of 87.84%, a specificity of 55.56%, a positive predictive value of 64.36%, a negative predictive value of 83.33%, a likelihood ratio+of 1.98, a likelihood ratio-de 0.22 and a kappa index of 0.4272, in the identification of preneoplastic lesions of the stomach in a population with a disease prevalence of 47.74%. Conclusions: The endoscopic visualization of the gastrointestinal mucosa, allows a moderate and fast identification of early preneoplastic lesions, providing an opportunity of its early histopathological diagnosis. © 2007 Elsevier España, S.L.
