ROCHA, Nicolás et al. Correlation of endoscopic and histological findings in diagnosis of gastrointestinal metaplasia in patients referred to the Clinica Colombia for upper endoscopies. Rev Col Gastroenterol [online]. 2012, vol.27, n.4, pp.263-268. ISSN 0120-9957.

Introduction: Intestinal metaplasia is one step towards the final process known as gastric cancer. Correct identification through a biopsy taken endoscopically is vital for histological confirmation. In our surroundings the relationship between endoscopic findings when intestinal metaplasia is suspected and histological confirmation are not understood. This study aims to determine the true correlation between endoscopic findings suggestive of metaplasia and their histological counterparts. Methods: This was an observational and analytical study undertaken at the Clinica Colombia. Patients who were suspected of having intestinal metaplasia following endoscopic examinations were included. Patients with prior histories of metaplasia and gastric cancer were excluded. Statistical evaluation was performed using STATA 11. Results: A total of 766 patients suspected of having intestinal metaplasias following endoscopic examination were included. 543 (70%) were confirmed histologically. Patients who most frequently had no correlation between suspicion following endoscopy and histological findings included those with chronic gastritis, foveolar hyperplasia, and reactive gastropathy. The positive predictive value of endoscopic findings was close to 71%. Conclusions: Although the correlation was close to 70%, prospective and multicenter studies, as well as studies using chromoendoscopy, are needed in order to evaluate agreement between the two methods, to determine predictive endoscopic variables for severity and for types of metaplasia, and to determine protocols for monitoring these patients.
