Abstract:
Numerous outbreaks of duodenoscope-associated transmission of multi-drug resistant bacteria have recently been reported. Unlike prior episodes of endoscope-transmitted infections, the latest outbreaks have occurred despite strict adherence to duodenoscope reprocessing guidelines. The current standard for all flexible endoscope reprocessing includes pre-cleaning, leak testing, an additional manual cleaning step, and high-level disinfection. When these steps are strictly followed, the risk of infection transmission during endoscopy is exceedingly rare. However, due to its complex design, the duodenoscope may not be able to be adequately disinfected using the current reprocessing standards. Supplemental measures to enhance scope reprocessing have subsequently been recommended to reduce the infection risk in patients undergoing endoscopic retrograde cholangiopancreatography. These methods are likely short-term solutions that have yet to be validated regarded their effectiveness. Additional approaches to monitor the quality of duodenoscope reprocessing may also be useful. Ultimately, a definitive, yet logistically feasible, method of duodenoscope reprocessing is required to ensure the safety of our patients.
Insights
Duodenoscope reprocessing guidelines may be insufficient for preventing multi-drug resistant bacteria transmission. New methods are needed to ensure patient safety during endoscopic retrograde cholangiopancreatography procedures.
Area of Science:
- Infectious Diseases
- Medical Device Reprocessing
- Gastroenterology
Background:
- Recent duodenoscope outbreaks involve multi-drug resistant bacteria transmission.
- These outbreaks persist despite adherence to current reprocessing guidelines.
Purpose of the Study:
- To address the inadequacy of current duodenoscope reprocessing standards.
- To highlight the need for improved disinfection methods for patient safety.
Main Methods:
- Review of current flexible endoscope reprocessing guidelines.
- Analysis of duodenoscope design challenges in disinfection.
- Evaluation of supplemental reprocessing measures and monitoring approaches.
Main Results:
- Current reprocessing standards may not adequately disinfect complex duodenoscopes.
- Supplemental measures are short-term solutions lacking validated effectiveness.
Conclusions:
- A definitive, feasible duodenoscope reprocessing method is essential.
- Enhanced reprocessing and monitoring are crucial to prevent infection transmission.

The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail...

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
