Background and Aims

Duodenoscope contamination is associated with notable patient morbidity and mortality and can occur despite high-level disinfection protocols, requiring a solution that protects against contamination of the endoscope in the first place.

Methods

We assessed a newly cleared, single-use device to seal the distal end of duodenoscopes while preserving optics and other endoscope functionality and tested its ability to protect against contamination using dye immersion tests and microbial inoculation.

Results

Dye immersion tests revealed a complete seal with no leakage. Rigorous microbial challenge tests showed the device can both protect against contamination of the endoscope by external microbes (“outside-in” protection) and shield instruments from contact with pre-existing microbial biofilm on or around the elevator that may have survived reprocessing (“inside-out” protection). Optical and mechanical performance of the endoscope was not compromised by the addition of the device.

Conclusions

The results show that this disposable device provides 2-way protection to the duodenoscope from microbial contamination, without the potential for disrupting current equipment, technique, and workflow.

新型有效的一次性设备,可为十二指肠镜提供两路保护,免受微生物污染。

背景和目标

十二指肠镜的污染与患者明显的发病率和死亡率有关,尽管有高水平的消毒方案,但十二指肠镜的污染仍可能发生,因此首先需要一种防止内窥镜污染的解决方案。

方法

我们评估了一种新近使用过的一次性设备,用于密封十二指肠镜的远端,同时保留光学器件和其他内窥镜的功能,并通过染料浸入测试和微生物接种测试了其防止污染的能力。

结果

染料浸没测试显示出完整的密封,没有泄漏。严格的微生物挑战测试表明,该设备既可以防止内窥镜受到外部微生物的污染(“从外而内”的保护),又可以保护仪器避免与可能在后处理中幸存下来的电梯上或周围的微生物生物膜接触(“内部”)。 -out”保护)。内窥镜的光学和机械性能并未因添加该设备而受到损害。

结论

结果表明,这种一次性设备可为十二指肠镜提供两向保护,使其免受微生物污染,而不会破坏当前的设备,技术和工作流程。
