目的 :探讨幽门螺杆菌 (HP)与胃十二指肠溃疡的关系。方法 :电子胃镜证实有溃疡病灶 ,取胃粘膜作HP检测为阳性者 ,即可判断有HP感染。结果 :14 70例消化性溃疡患者中 ,HP感染阳性 1310例 ,阴性 160例 ,感染率为 89.1% ;其中十二指肠球部溃病HP感染阳性 10 2 0例 ,阴性 160例 ,感染率为 86.4% ;胃溃疡HP感染率达 10 0 % ;复合性溃疡HP感染率达 10 0 %。结论 :提示溃疡病的元凶仍是HP ,治疗消化性溃疡同时必须采取HP的根治治疗 Objective: To investigate the relationship between Helicobacter pylori (HP) and gastroduodenal ulcer. Methods: Electron gastroscopy confirmed ulcer lesions, take the gastric mucosa as HP test positive, you can determine the HP infection. Results: Of the 14 70 patients with peptic ulcer, 1310 were positive for HP infection and 160 were negative, the infection rate was 89.1%. The positive rate of HP infection in duodenal ulcer was 102.0 and 160 were negative, the infection rate Was 86.4%. The HP infection rate of gastric ulcer was 100%. The HP infection rate of complex ulcer was 100%. Conclusion: Tip of ulcer disease is still the culprit HP, peptic ulcer treatment must also take the HP radical treatment
