RESUMO
BACKGROUND: The cause of cancer in the gastric stump is multifactorial, and Helicobacter pylori is one of these factors. Its eradication has been recommended; however, there are few studies about of H. pylori eradication in gastrectomized patients. METHODS: Twenty gastrectomized patients with gastric adenocarcinoma and Roux-en-Y reconstruction (study group) infected by H. pylori were compared with nongastrectomized patients (control group) also infected by H. pylori. The presence of H. pylori was determined by the ultra-quick urease test and from a histological sample obtained by endoscopy. Both groups received the same triple therapy regimen. RESULTS: The rate of eradication of H. pylori in the study group was 90% and in the control group, it was 85%. Sex, age, and postoperative time did not influence the rate of eradication. CONCLUSION: There were no differences in the efficacy of H. pylori eradication between the two groups; therefore, the triple therapy regimen is effective for the eradication of H. pylori in gastrectomized patients with a Roux-en-Y reconstruction.
