目的 :明确复合性溃疡 (CU )患者幽门螺杆菌 (Hp)根除后再感染和溃疡复发情况。方法 :将 93例随机分为两组。A组奥克 40 m g,每天 1次 ,治疗 2周 ;B组奥克 40 mg,每天 1次 ,阿莫西林 5 0 0 mg和甲硝唑 2 0 0 mg每天 3次 ,治疗两周。A、B两组再以奥克 2 0 m g每日 1次 ,维持治疗 4周 ,疗程结束 4周后复查 Hp。并进行半年、一年定期随访。结果 :A、B组溃疡愈合率分别为 84.78%、91.4% (P>0 .0 5 ) ,Hp根除率分别为 41.30 %、87.2 3% (P<0 .0 5 )。结论 :根除Hp可防止复合性溃疡复发 ,已根除 Hp者溃疡复发大多数与 Hp再感染有关。以预防溃疡复发为目的的 Hp根除疗法 ,同样适用于高 Hp感染率地区。
Objective: To determine the recurrence of H. pylori (Hp) re-infection and ulcer recurrence in patients with complex ulcer (CU). Methods: 93 cases were randomly divided into two groups. A group of 40 grams oak, once a day for 2 weeks; B group Occitan 40 mg once daily, amoxicillin 500 mg and metronidazole 200 mg 3 times a day for two weeks. Groups A and B were treated with Oerlikon 20 m g once daily for 4 weeks, and Hp was examined 4 weeks after the end of treatment. And for six months, a year regular follow-up. Results: The healing rates of ulcer in groups A and B were 84.78% and 91.4%, respectively (P> 0.05). The rates of Hp eradication were 41.30% and 87.2 3%, respectively (P <0.05). Conclusion: The eradication of Hp can prevent the recurrence of complex ulcer. Most of the ulcer recurrences that have eradicated Hp are associated with reinfection of Hp. Hp eradication therapy aimed at preventing ulcer recurrence is equally applicable to areas with high Hp infection rates.
