A survey of the medical literature reveals conflicting data as to whether bacteremia occurs during endoscopic examination of the lower gastrointestinal tract. In an attempt to study this problem a prospective study was undertaken, and the first arm of the study included patients undergoing colonoscopy. The second arm of the study, comprising patients undergoing proctosigmoidoscopy, will be presented subsequently. Fifty-one patients undergoing colonoscopy were studied. Excluded from the study were patients with elevation of temperature above 101 degrees F, inflammatory bowel disease, diarrhea, valvular heart disease, vascular prosthesis, chemotherapy, or immunosuppression. Aerobic and anaerobic culture were done before and after the procedure, as well as at timed intervals during the procedure. Whenever biopsy or polypectomy were carried out, further cultures were done. Skin cultures were done from venipuncture sites. In one patient (2 per cent) Staphylococcus epidermidis was found in more than one set of cultures. Polypectomy or biopsy were not associated with bacteremia.
一项医学文献调查显示，关于在下消化道内镜检查期间是否会发生菌血症，数据存在冲突。为了研究这个问题，我们进行了一项前瞻性研究，该研究的第一组包括接受结肠镜检查的患者。研究的第二组包括接受直肠乙状结肠镜检查的患者，后续将予以呈现。我们对51名接受结肠镜检查的患者进行了研究。排除在研究之外的患者包括体温高于101华氏度、患有炎症性肠病、腹泻、瓣膜性心脏病、血管假体、化疗或免疫抑制的患者。在手术前后以及手术期间的定时间隔进行需氧和厌氧培养。每当进行活检或息肉切除时，都会进一步培养。从静脉穿刺部位进行皮肤培养。在一名患者（2%）的多组培养物中发现了表皮葡萄球菌。息肉切除或活检与菌血症无关。
