目的:比较果胶铋三联和四联疗法治疗幽门螺旋杆菌(Hp)阳性的消化性溃疡的疗效。方法:经电子胃镜和快速尿素酶方法确诊的Hp阳性胃溃疡和十二指肠溃疡共125例,按治疗方法分为2组,三联疗法组60例:果胶铋0.2 g 3次/日,克拉霉素0.5 g 2次/日...目的:比较果胶铋三联和四联疗法治疗幽门螺旋杆菌(Hp)阳性的消化性溃疡的疗效。方法:经电子胃镜和快速尿素酶方法确诊的Hp阳性胃溃疡和十二指肠溃疡共125例,按治疗方法分为2组,三联疗法组60例:果胶铋0.2 g 3次/日,克拉霉素0.5 g 2次/日,甲硝唑0.4 g,2次/日,1疗程为2周;四联疗法组:果胶铋、甲硝唑、克拉霉素用法用量同三联疗法,加用雷贝拉唑20 mg,2次/日,1个疗程为1周。疗程结束4周后行电子胃镜及快速尿素酶试验复检。结果:125例均获随访,四联疗法组总有效率高于三联疗法组(P<0.05),症状缓解时间较三联疗法组短(P<0.01),不良反应发生率低于三联疗法组(P<0.05),Hp根除率与三联疗法差异无统计学意义(P>0.05)。结论:含雷贝拉唑的四联疗法治疗Hp阳性的胃溃疡、十二指肠溃疡,其症状缓解时间、溃疡愈合,不良反应等方面优于三联疗法。展开更多
