In order to determine the risk of bacteremia from colonoscopy, we cultured blood specimens from 40 patients the day before laxative and enema preparation; right after such preparation; and 15 min, 1 hr, and 4 hr after colonscopy. Bacteremia was not induced by either the vigorous preparation or the colonscopy which, in 27 patients, included polypectomy, biopsy, and/or fulgurations. On the basis of our data, we conclude that the risk of bacteremia following colonoscopy is small, and we doubt the need of antibiotic prophylaxis for those with susceptible hearts.
为了确定结肠镜检查导致菌血症的风险，我们采集了40例患者在进行泻药和灌肠准备前一天、准备刚结束后、结肠镜检查后15分钟、1小时和4小时的血标本进行培养。无论是强力准备还是结肠镜检查（27例患者的检查包括息肉切除术、活检和/或电灼术）均未诱发菌血症。根据我们的数据，我们得出结论，结肠镜检查后发生菌血症的风险很小，并且我们怀疑心脏易感患者是否需要预防性使用抗生素。
