NEJM:急性上消化道出血内镜检查的时机

2020-04-02 MedSci原创 MedSci原创

在伴有出血或死亡风险的急性上消化道出血患者中,与在消化科就诊后6-24小时内进行内窥镜检查相比,就诊后6小时内进行内窥镜检查与30天死亡率之间并无相关性。

急性上消化道出血患者被建议在消化科就诊后24小时内接受窥镜检查。在短于24小时的时间段内进行内窥镜检查的作用还没有被充分明确。近日,顶级医学期刊NEJM上发表了一篇研究文章,研究人员旨在评估紧急内窥镜检查是否能改善那些进一步出血或死亡高风险的患者预后。

研究人员随机分配了有明显症状和Glasgow-Blatchford评分12分或更高(评分范围从0到23分,评分越高,出血或死亡的风险越高)的急性上消化道出血患者,在消化科就诊后6小时内(急诊内镜组)或6-24小时内(早期内镜组)进行胃肠镜检查。该研究的主要终点是随机化后30天内因任何原因死亡。

该研究共纳入516例患者,急诊内镜组30天死亡率为8.9%(258例中有23例),早期内镜组30天死亡率为6.6%(258例中有17例)(差异为2.3个百分点;95%置信区间[CI]为-2.3到6.9)。急诊内镜组30天内再次出血患有有28例(10.9%),早期内镜组有20例(7.8%)(差异为3.1个百分点;95%CI为-1.9至8.1)。急诊内镜组158例(66.4%)消化性溃疡患者中,105例(66.4%)在首次内镜检查中发现有活动性出血或可见血管的溃疡,而早期内镜组159例(47.8%)中有76例(47.8%)在首次内镜检查中发现溃疡。急诊内镜组155例(60.1%)患者,早期内镜组125例(48.4%)患者在内镜下进行内镜止血治疗。

由此可见,在伴有出血或死亡风险的急性上消化道出血患者中,与在消化科就诊后6-24小时内进行内窥镜检查相比,就诊后6小时内进行内窥镜检查与30天死亡率之间并无相关性。
