Objective To evaluate the consistency between Kyoto classification scoring of gastritis and modified Kyoto classification scoring of gastritis in directly determining <i>Helicobacter pylori</i> （Hp） infection under white light endoscopy by endoscopists with ¹³C urea breath test， and to clarify the clinical application value of the modified Kyoto classification scoring of gastritis. Methods Digestive endoscopists in a county hospital in Chongqing received special training on the Kyoto classification of gastritis. Patients who underwent both the upper gastrointestinal endoscopy and ¹³C urea breath test within one week were screened. At the same time， the Kyoto classification scoring of gastritis and the modified Kyoto classification scoring of gastritis were used to score the endoscopic gastric mucosa characteristics of the target population. The total score was calculated and compared with the ¹³C urea breath test. Results A total of 1 342 patients were included in the study. The sensitivity of the Kyoto classification scoring of gastritis and the modified Kyoto classification scoring of gastritis for the diagnosis of Hp infection under white light endoscopy were 74.03% and 90.70%， the specificity was 95.85% and 95.39%， and the positive predictive values were 80.93% and 82.39%， the negative predictive values were 93.94% and 97.73%， respectively. The sensitivity， negative predictive value and AUC of the modified Kyoto classification scoring of gastritis in the diagnosis of Hp infection under white light endoscopy had statistical significance compared with the Kyoto classification scoring of gastritis （all <i>P &lt;</i>0.01）. Conclusion For endoscopists receiving special training for Kyoto classification of gastritis， the modified Kyoto classification scoring of gastritis yields high diagnostic consistency in directly determining Hp infection under white light endoscopy.
