1.在中国人群中尚无消化性溃疡出血的临床特征和预后的全国范围的流行病学研究结果。
2.作者所在单位牵头进行了一项全国范围内的多中心内镜研究。

消化性溃疡出血是非常常见的一项临床急症。然而在中国人群中目前仍缺乏消化性溃疡出血临床特点和临床转归的流行病学调查研究。本研究的目的在于描述我国,特别是高危人群中消化性溃疡出血的临床现象和管理方案。【原文下载

我国上海第二军医大学长海医院李兆申等人统计一项多中心内镜研究结果(该项研究由上海、北京、广东、浙江、四川、福建、吉林、甘肃、湖北、陕西等国省市多家大型医院共同参与完成)。研究对象为2010年10月至2011年6月所有经内镜检查证实的消化性溃疡出血的患者。统计数据包括性别、年龄、症状以及内镜检查结果、Forrest分级、内镜以及药物治疗情况。内镜下Forrest分级为Ia至IIb被认为是高风险溃疡(Forrest分级:为内镜下消化性溃疡出血分级方法。Ia:喷射样出血,Ib:活动性渗血;IIa:血管裸露,IIb:血凝块附,IIc溃疡面可见黑色基底;III基底洁净。推荐对Forrest分级Ia-IIb的出血病变进行内镜下止血治疗。图2)。同时记录再出血率、手术治疗率以及死亡率。

研究共纳入了1006例患者。437例(43.4%)为高风险消化性溃疡。在高风险消化性溃疡患者中,110例(25.2%)接受了内镜下止血治疗,治疗成功率为99.1%。在第1-3天高风险患者中接受成功内镜治疗组患者与未进行内镜治疗组患者的再出血几率分别为11.0%和10.4%,在第4-5天和6-30天两组患者的再出血几率分别为3.7% vs 3.7%和0.9% vs 1.5%。高风险患者中接受成功内镜治疗组患者与未进行内镜治疗组患者的手术治疗率分别为1.8%(2/110)和1.8%(6/327)。在9个月的研究周期中,2例(0.6%)高风险消化性溃疡出血患者死亡,而高风险消化性溃疡出血患者总死亡率为0.46%(2/437)。

研究结果表明中国消化性溃疡人群中,高风险消化性溃疡出血患者比例为43.4%,成功进行了内镜下治疗患者的再出血率、手术治疗率分别为15.6%和 1.8%,总死亡率为0.46%。

研究背景:

非静脉曲张性上消化道出血(NVUGIB)是最常见的内科急症之一。其每年发生率约为50-150/100000人。在美国每年因非静脉曲张性上消化道出血住院的患者超过30万人。非静脉曲张性上消化道出血最常见的原因是胃或十二指肠溃疡引起的。因根除幽门螺杆菌治疗的发展和内镜技术的不断完善,消化性溃疡引起的非静脉曲张性上消化道出血的死亡率在过去的20年里显著下降。

之前报道消化性溃疡出血的死亡率始终在5%-14%范围内变化。而引起消化性溃疡出血的死亡率一直相对稳定的原因尚不清楚。社会老龄化的发展,消化性出血引起的相关合并症发生率增加可能是部分原因。在中国,幽门螺杆菌的感染和消化性溃疡均为高发。几项大型人群统计研究及内镜研究表明在一般人群和以消化道症状就诊的门诊人群中,消化性溃疡的发生率都在20%以上。

然而在中国人群中尚无消化性溃疡出血的临床特征和预后的全国范围的流行病学研究结果。因此,在中国人群中关于高危消化性溃疡出血人群的比例、患者药物及内镜治疗情况以及再出血率、死亡率等更详细的信息需要进一步统计研究。为了达到这一目的作者进行了一项全国范围内的多中心内镜研究,为更好的了解消化性溃疡出血在我国的发病特征提供依据。
