The increasing number of endoscopic procedures performed and their increasing invasiveness mean that endoscopy of the gastrointestinal tract is associated with the risk of transmitting pathogenic microorganisms through infected equipment or contact with other patients and medical staff. In order to ensure protection of the health of both patients and medical staff, endoscopy laboratories should meet high hygiene standards. The results of tests of the microbiological cleanliness of surfaces and equipment of an endoscopic examination laboratory performed in the period from January to December 2019 at the Provincial Clinical Hospital No. 2 in Rzeszow were assessed retrospectively. Samples for testing were collected by swabbing from places where microbiological contamination was the most likely and cleaning was the most difficult. In the analyzed period, a total of 86 samples were collected for microbiological tests, of which positive results accounted for 6.9%. Positive results were obtained mainly from swabs collected from wet surfaces (66.7%). Most of the isolated microorganisms were Gram-negative bacteria (66.7% of all positive tests) and they were: Acinetobacter junii, Ralstonia pickettii, and Achromobacter denitrificans. The condition of the microbiological cleanliness of the surfaces and equipment of the endoscopic examination laboratory was satisfactory. A very low level of microbiological contamination of the tested items indicates occasional shortcomings in the decontamination processes. Since microorganisms isolated from the collected samples may be the cause of infection in patients and medical personnel, it is necessary to verify the decontamination procedures applied and to continue periodic microbiological monitoring of their effectiveness.

内窥镜检查实验室表面和设备的微生物清洁状态——来自波兰南部参考三级临床内窥镜中心的数据

越来越多的内窥镜手术及其侵入性增加意味着胃肠道内窥镜检查与通过受感染设备传播病原微生物或与其他患者和医务人员接触的风险有关。为了保障患者和医务人员的健康，内窥镜实验室应达到高卫生标准。回顾性评估了2019年1月至2019年12月在热舒夫省第二临床医院进行的内窥镜检查实验室的表面和设备微生物清洁度测试结果。用于测试的样本是从最有可能被微生物污染和最难清洁的地方通过擦拭收集的。分析期内，共采集86份样本进行微生物检测，阳性结果占6.9%。阳性结果主要来自从湿表面收集的拭子 (66.7%)。大多数分离的微生物是革兰氏阴性菌（占所有阳性检测的 66.7%），它们是：不动杆菌琼氏，青枯pickettii和无色脱氮。内窥镜检查实验室的表面和设备的微生物清洁状况良好。被测物品的微生物污染水平非常低表明去污过程中偶尔会出现缺陷。由于从采集的样本中分离出的微生物可能是患者和医务人员感染的原因，因此有必要验证所采用的去污程序并继续对其有效性进行定期微生物监测。
