A prospective study was undertaken to determine the frequency of bacteremia after endoscopy of the upper gastrointestinal tract. Three of 100 patients (3%) demonstrated positive blood cultures after the endoscopic procedure. Bacteriologic surveys disclosed that routine cleansing procedures of the endoscopy room and the endoscope itself frequently failed to achieve optimal sterile conditions. Particularly noteworthy was the growth of Enterobacter liquefaciens and Candida albicans on one occasion from the endoscope tip. We conclude that, although the incidence of postendoscopy positive blood cultures is low, a more vigorous approach to using clean equipment in clean surroundings is needed when dealing with a potentially susceptible host.
进行了一项前瞻性研究，以确定上消化道内镜检查后菌血症的发生率。100例患者中有3例（3%）在内镜检查后血培养呈阳性。细菌学调查显示，内镜室和内镜本身的常规清洁程序常常无法达到最佳无菌条件。特别值得注意的是，有一次在内镜尖端培养出了液化肠杆菌和白色念珠菌。我们得出结论，尽管内镜检查后血培养阳性的发生率较低，但在处理潜在易感宿主时，需要采取更积极的措施，在清洁的环境中使用清洁的设备。
