The Fisher Exact Test and a significance level of 5 % were used. Results: Of 80 patients, the majority was women (65 %) and the mean age was 52.4 years. 76.3 % received standard triple therapy and the majority obtained eradication of H. pylori (75 %). It is observed that the patients who received triple therapy had 62 % and 17.7 % higher frequency of eradication of H. pylori, compared to those who receivedBOTFandMOCAtherapy;respectively(82 % vs. 20 % vs. 64.3 %). An association was observed betweenthepresenceofmetaplasiaandtheeradication of H. pylori (89.3 % vs. 67.3 %). Conclusion: Most patients eradicated H. pylori, particularly with the use of standard triple therapy.
