Judith A. Kwakman et al. Persistent contamination of a duodenoscope working channel in a non-clinical simulated ERCP setting

Three duodenoscopes were contaminated repeatedly with a broth containing four different microorganisms at a supraphysiological concentration of the average duodenal flora in this in vitro non-clinical ERCP simulation study. After 60 cycles, it was found that one duodenoscope had persistent contamination with one of the four organisms (Pseudomonas aeruginosa). This finding could be suggestive of biofilm formation, although that was not visua„lized by microscopic assessment.
