AIM: One of the causes for gastric cancer is by Helicobacter pylori (H. pylori) infection, which implies that it is important to determine the H. pylori infection status during gastric cancer screening in Japan. Therefore, effective learning methods must be provided for diagnosing gastric mucosal alterations caused by H. pylori. Methods: Study subjects included 27 physicians, 12 radiologic technologists, and one other who participated in the eighth meeting of the Gastric Cancer Screening Study Group, in consideration of H. pylori infection, held in June 2017. Before and after the lecture on H. pylori infection diagnosis using gastric radiographic imaging and endoscopy, we compared the changes in the correct answer rates to the question of choosing from among three H. pylori infection statuses, namely uninfected, currently infected, and previously infected. The answers after the lecture were shared among the participants using an interactive system, Answer Pad. Results: The correct answer rate after the lecture increased with both gastric radiographic imaging and endoscopy; however, a significant difference from 54% to 69% was observed with gastric radiographic imaging among the beginners (p < 0.01). Conclusions: The lecture of our group using radiographic and endoscopic images significantly increased the learning effect on the diagnosis of H. pylori infection status, especially for beginners.
