溃疡病的病因和复发因素都很复杂,而胃幽门弯曲菌样细菌的发现又使溃疡病的研究有了新的推进。消化性溃疡复发率很高,防止复发亦较困难;据统计50～95％的消化性溃疡在五年内复发,这就构成了消化性溃疡的慢性化。对复发因素的探讨很多,现着重就几个问题进行讨论,希能达到提高疗效,减少和防止复发的目的。 The etiology and recurrence of ulcer disease are complex, and the discovery of Campylobacter pylori-like bacteria makes the study of ulcer disease a new advance. Peptic ulcer recurrence rate is high, to prevent recurrence is more difficult; according to statistics, 50 to 95% of peptic ulcer recurrence within five years, which constitutes a peptic ulcer chronic. There are many discussions on the relapse factors, and we are going to discuss several issues in the future. We hope to achieve the goal of improving curative effect and reducing and preventing relapse.
