Objective: To determine the utility of the stain with blue of methylene in the identification of antral and angular gastric early intestinal metaplasia. Materials and methods: Descriptive, prospective study. Evaluating 75 patients of the service of gastroenterology “Dr. Simón Beker” in the General Hospital of the West “Dr. Jose Gregorio Hernandez” during the period May - October 2008. Results: 75 patients evaluated, in the group A with intestinal metaplasia endoscopic suspicion of metaplasia, was confimed with histology in the 71.4%. In group B, with tinción and without endoscopic suspicion, the histology was confirmed in 40.9%, and in group C without suspicion and without tinción, was confirmed in 36% of the patient with a statistically significant result (p=<0,020). The stain it allowed: in 26 (92.8%) patient delimit with greater exactitude the edges of the suspicious injuries, in 12 (42.8%) patient to delimit the extension of the injury which was greater to the described one in conventional endoscopy, in 16 (57.1%) patient ones allowed to emphasize a greater number of injuries. Conclusion: The stain with blue of methylene is a useful procedure, and would have to be used like investigation.
