In US emergency departments (EDs), the physician has limited ability to evaluate for common and serious conditions of the gastrointestinal (GI) mucosa such as a bleeding peptic ulcer. Although many bleeding lesions are self-limited, the majority of these patients require emergency hospitalization for upper endoscopy (EGD). We conducted a clinical trial to determine if ED risk stratification with video capsule endoscopy (VCE) reduces hospitalization rates for low-risk to moderate-risk patients with suspected upper GI bleeding.
We conducted a randomized controlled trial at 3 urban academic EDs. Inclusion criteria included signs of upper GI bleeding and a Glasgow Blatchford score <6. Patients were randomly assigned to 1 of the following 2 treatment arms: (1) an experimental arm that included VCE risk stratification and brief ED observation versus (2) a standard care arm that included admission for inpatient EGD. The primary outcome was hospital admission. Patients were followed for 7 and 30 days to assess for rebleeding events and revisits to the hospital.
The trial was terminated early as a result of low accrual. The trial was also terminated early because of a need to repurpose all staff to respond to the coronavirus disease 2019 pandemic. A total of 24 patients were enrolled in the study. In the experimental group, 2/11 (18.2%) patients were admitted to the hospital, and in the standard of care group, 10/13 (76.9%) patients were admitted to the hospital ( = 0.012). There was no difference in safety on day 7 and day 30 after the index ED visit.
VCE is a potential strategy to decrease admissions for upper GI bleeding, though further study with a larger cohort is required before this approach can be recommended.
在美国急诊科(EDs),医生评估胃肠道(GI)黏膜常见和严重疾病(如消化性溃疡出血)的能力有限。尽管许多出血性病变是自限性的,但这些患者中的大多数需要紧急住院进行上消化道内镜检查(EGD)。我们进行了一项临床试验,以确定使用视频胶囊内镜(VCE)进行急诊科风险分层是否能降低疑似上消化道出血的低风险至中度风险患者的住院率。
我们在3家城市学术性急诊科进行了一项随机对照试验。纳入标准包括上消化道出血的体征和格拉斯哥布莱奇福德评分<6。患者被随机分配到以下2个治疗组中的1组:(1)试验组,包括VCE风险分层和急诊科简短观察;(2)标准治疗组,包括住院接受住院EGD检查。主要结局是住院。对患者进行7天和30天的随访,以评估再出血事件和再次入院情况。
由于入组率低,试验提前终止。由于需要重新安排所有工作人员以应对2019年冠状病毒病大流行,试验也提前终止。共有24名患者纳入研究。试验组中,2/11(18.2%)的患者住院,标准治疗组中,10/13(76.9%)的患者住院(P = 0.012)。在急诊科首次就诊后第7天和第30天,安全性方面无差异。
VCE是一种可能降低上消化道出血住院率的策略,不过在推荐这种方法之前,还需要对更大的队列进行进一步研究。
