Objective To analyze the clinical and pathological features of primary bile reflux gastritis(BRG).Methods Endoscopy,Helicobacter pylori(H.pylori) detection,and histopathologic examination were performed in 218 patients with primary BRG(observed group) and 236 patients with simple chronic gastritis(SCG,control group) as identified by gastroscope in order to analyze the endoscopic abnormalities,the frequency of H.pylori infection,pathological features and scores of inflammation.Results The
