What is clear right now is that there is no single root cause and no single "fix" for the challenges of endoscope reprocessing. Studies show that even with the best of intentions, current reprocessing guidelines are not always followed to the letter.
A study published online Aug 5 in AJIC1 provides evidence that contamination remains even when observers document that each and every step is completed properly. Not only that, but this study showed that contamination remains even after cleaning (or multiple rounds of cleaning and disinfection) on colonoscopes and gastroscopes. Thus, it is clear that duodenoscopes are not the only type of flexible endoscope that requires further attention.
