Recommendations in managing patients with nonvariceal upper gastrointestinal bleeding were recently updated, addressing resuscitation, risk assessment and pre-endoscopic care, endoscopy, pharmacotherapy, and secondary prophylaxis. Initial adequate resuscitation and risk stratification using validated scales remain critical. Intravenous erythromycin improves visualization when likely to find blood in the stomach. Pre-endoscopic proton pump inhibition (PPI) does not improve outcomes, but downstages high-risk endoscopic lesions and may be considered. In patients on anticoagulants, correction of a coagulopathy is recommended, but should not delay early endoscopy (within 24 h), as it improves clinical outcomes. In patients with high-risk endoscopic stigmata, although better than doing nothing, epinephrine injection alone provides suboptimal efficacy and should be combined with another modality such as clips, thermal or sclerosant injection, which are also efficacious alone. Following an attempt at dislodgment, adherent clots can be treated with high-dose intravenous PPI infusion alone (80 mg bolus and 8 mg/h for 3 days) or following endoscopic hemostasis. The combination is indicated for all other patients with high-risk stigmata as there is currently a lack of high-quality generalizable data supporting other intravenous or oral PPI regimens. A second-look endoscopy is recommended only selectively after endoscopic hemostasis. A negative Helicobacter pylori test requires confirmation in the acute setting. Following appropriate discussions, acetylsalicylic acid (ASA) can soon be restarted acutely after bleeding; long-term PPI co-therapy is imperative in patients having bled on nonsteroidal anti-inflammatory drugs if still needed (preferably with a cyclooxygenase-2, if appropriate) or ASA (not clopidogrel alone). Further work is needed to implement and disseminate these recommendations.
非静脉曲张性上消化道出血患者的管理建议最近已更新,涉及复苏、风险评估与内镜检查前护理、内镜检查、药物治疗及二级预防。采用经过验证的量表进行初始充分复苏和风险分层仍然至关重要。静脉注射红霉素在胃内可能有血时可改善视野。内镜检查前使用质子泵抑制剂(PPI)并不能改善预后,但可使高危内镜病变降级,可予以考虑。对于服用抗凝剂的患者,建议纠正凝血障碍,但不应延迟早期内镜检查(24小时内),因为这可改善临床结局。对于内镜下有高危征象的患者,尽管单独注射肾上腺素比不采取任何措施要好,但疗效欠佳,应与其他方法联合使用,如夹子、热凝或硬化剂注射,这些方法单独使用也有效。在尝试清除血栓后,附着的血凝块可单独用大剂量静脉注射PPI输注治疗(80毫克推注,8毫克/小时,持续3天)或在内镜止血后治疗。对于所有其他有高危征象的患者,建议联合使用,因为目前缺乏支持其他静脉或口服PPI方案的高质量可推广数据。仅在内镜止血后有选择地推荐进行二次内镜检查。急性情况下幽门螺杆菌检测阴性需要确认。经过适当讨论后,出血后可很快重新急性启动阿司匹林(ASA)治疗;对于因非甾体抗炎药出血的患者,如果仍有必要(如有可能,最好使用环氧化酶-2抑制剂)或服用ASA(而非仅使用氯吡格雷),长期联合使用PPI至关重要。需要进一步开展工作以实施和推广这些建议。
