十二指肠镜感染风险与清洗消毒

Duodenoscopy related infection risk and duodenoscope cleaning and disinfection

随着内镜微创技术的发展,十二指肠镜作为诊断和治疗胆胰疾病不可缺少的设备已广泛应用于临床.近年来,关于十二指肠镜引起的感染爆发事件报道,使得十二指肠镜清洗消毒方面的关注度不断提高.十二指肠镜由于本身的结构设计复杂,与其他多个工作部件和管腔相联,所有的部件与孔道必须经过细致的清洗消毒过程,否则容易导致清洗消毒的失败,并引发医院感染事件的爆发,从而威胁患者生命安全.因此分析影响十二指肠镜清洗消毒效果的因素,采取有效措施,做好内镜清洗消毒工作,防止院内感染事件发生,具有积极的现实意义.本文就十二指肠的感染风险与清洗消毒相关问题进行简要论述.

With the development of minimally invasive techniques,duodenoscope,as an instrument for diagnosis and treatment of pancreaticobiliary diseases,has been gradually applied in clinical practice.Iatrogenic infection caused by duodenoscopy is a well-documented complication,which has gained extensive attention especially in duodenoscope cleaning and disinfecting.It has been postulated that the complexity in design of duodenoscope makes cleaning difficult and poses a risk for nosocomial infections.As such,it is of positive practical significance to analyze the factors that affect cleaning and disinfecting and to take effective measures to do them better,in order to prevent nosocomial infection.This paper briefly reviews the cleaning and sterilizing of duodenoscope and the risk of infection associated with duodenoscopy.
