幽门螺杆菌(Helicobacter pylori,Hp)1983年由Warren及Marshall首次报道,其感染与消化性溃疡、慢性胃炎、胃切除后残胃炎、胃癌、MALT淋巴瘤、NSAID性溃疡密切相关。人群中Hp感染率约50%-90%,检出率在十二指肠溃疡高达95%-100%,胃溃疡达70%-90%[1]。故重视Hp感染的诊断极为重要 Helicobacter pylori (Hp) was first reported by Warren and Marshall in 1983 and its infection is closely related to peptic ulcer, chronic gastritis, residual gastritis after gastric resection, gastric cancer, MALT lymphoma and NSAID ulcer. Hp infection rate of about 50% -90% of the population, the detection rate of duodenal ulcer as high as 95% -100%, 70% -90% of gastric ulcer [1]. Therefore, the importance of diagnosis of Hp infection is extremely important
