Abstract
Objective: To clarify the reason for the low Helicobacter pylori (HP) eradication therapy performance rate following gastro-fluoroscopy in HP infection-induced gastritis, we compared the diagnostic accuracies of X-ray and endoscopic examinations as well the situations of performing HP eradication.
Methods: 7,328 subjects who received gastric cancer screening in 2015 were enrolled in this study. In interviews, we asked all subjects if their HP serum antibody titers had been measured and if they had undergone HP eradication therapy or not. In addition, the diagnostic accuracy for HP infection-induced gastritis was compared between the examinations.
Results: The positive predictive value for HP infection-induced gastritis by X-ray examination was 69.6%, whereas it was 62.0% for endoscopic examination. In contrast, the eradication performance rates were 20% and 80%, respectively, for each method.
Conclusions: The reason for the low eradication therapy performance rate for HP infection-induced gastritis diagnosed in X-ray examinations was considered not to be due examination accuracy but the requirements of the Japanese medical insurance system.
