【摘要】 目的了解在经内镜下逆行胰胆管造影术(ERCP)后行鼻胆管引流术(ENBD)的导管感染情况,研究鼻胆管导管感染危险因素及预防策略。方法回顾性分析2011年8月至2014年8月我院收治的218例行ERCP术后放置鼻胆管患者的导管感染率、相应的感染源及感染途径、感染细菌培养结果。结果 ERCP手术放置鼻胆管导管感染率为7.3%,感染源有胃肠道、导管堵塞及胆管自身因素;感染细菌培养结果主要为肺炎克雷伯菌、大肠埃希菌、铜绿假单胞菌、肠球菌及金黄色葡萄球菌、鲍曼不动杆菌。结论逆行胰胆管造影术后鼻胆管引流术后发生鼻胆管导管感染的概率低(7.3%),感染途径主要为胆肠逆行感染及经血、细菌感染以革兰阴性菌为主。更多还原

【Abstract】 Objective To analysis of the catheter related infections after endoscopic nano-billy drainage(ENBD)based on endoscopic retrograde cholangiopancreatography(ERCP). To study risk factors and preventive strategies of the catheter related infections afte ENBD. Methods The clinical data of 218 cases with ERCP in our hospital were collected from August 2011 to August 2014,which were analyzed retrospectively about infection rate,the corresponding source of infection and bacterial culture results. Results The infection rate of the catheter related infections after ENBD was 7.3%.The source of infection was gastrointestinal tract infection,catheter jam and bile duct. Infection bacterial mainly were klebsiella pneumoniae,E. coli,pseudomonas aeruginosa,enterococcus,staphylococcus aureus and acinetobacter baumannii. Conclusion The infection rate of the catheter related infections after ENBD is low. The route of infection is retroinfection or blood. Staphylococcus is the main strain of gram-positive bacterias.更多还原
