LIU BEJARANO, Humberto. Chronic atrophic gastritis: endoscopic and histological concordances, associated injuries and application of virtual chromoendoscopy. Rev. gastroenterol. Perú [online]. 2011, vol.31, n.2, pp.116-123. ISSN 1022-5129.

INTRODUCTION: Due to the poor agreement between endoscopy and histology, the gastric biopsy continues being the gold standard for the diagnosis of atrophic chronic gastritis. The Virtual chromoendoscopy system allows better observation of the gastric mucosa OBJECTIVE: Evaluate the agreement between the Kimura-Takemoto ´s endoscopic system classification and the histological system of OLGA (Operative for Link Assessment Gastritis), as well as to evaluate the application of the virtual chromoendoscopy METHODOLOGY: A prospective and longitudinal study of cohorts, 138 patients was include, using endoscopic system of atrophy by Kimura and Takemoto (K-T), with conventional optical and with the use of seventh filter of virtual chromoendoscopy ,then comparing with the histological findings of the OLGA pathology system, also were determinated injuries associated with respect to stage OLGA RESULTS: The kappa index of agreement between conventional endoscopy and the system OLGA was 0.859 and with the system of virtual chromoendoscopy was 0.822, the preneoplasic and neoplastic gastric lesions were associate to stages III and IV of atrophy CONCLUSIONS: The endoscopic and histological correlation with both systems isvery good, with or without the use of virtual chromoendoscopy.
