    Abstract:
    BACKGROUND/AIMS: In recent years, the role of Helicobacter pylori in gastritis of the residual stomach has attracted much attention. We investigated the prevalence of Helicobacter pylori in the residual stomach after distal gastrectomy for gastric cancer, as well as the correlations between Helicobacter pylori positivity and clinical characteristics or the severity of gastritis in the residual stomach. METHODOLOGY: The subjects were 66 patients with gastric cancer who underwent distal gastrectomy with Billroth I reconstruction at our department. Helicobacter pylori was detected by the 13C-urea breath test, and patients were considered to be Helicobacter pylori-positive if the delta 13C value was > 2.5@1000. RESULTS: The overall Helicobacter pylori positivity rate of the gastrectomy patients was a high 80.3%, with the rate being especially high in patients under 60 years of age and in those tested less than 5 years after surgery. There was a close relationship between Helicobacter pylori positivity and the severity of gastritis. CONCLUSIONS: Helicobacter pylori infection appears to cause the development of gastritis. Helicobacter pylori eradication needs to be taken into consideration in the management of Helicobacter pylori-positive patients after gastrectomy.
