Novel single-use duodenoscope compared with 3 models of reusable duodenoscopes for ERCP: a randomized bench-model comparison

Multidrug-resistant infectious outbreaks associated with duodenoscope reuse have been documented internationally. A single-use endoscope could eliminate exogenous patient-to-patient infection associated with ERCP.

The infectious risk of ERCP has historically been ascribed to biliary stasis and obstructive physiology from stones, strictures, or stents. Recent outbreaks, many of them from multidrug-resistant organisms (MDROs), have been attributed to the infectious carriage of the duodenoscope itself: so-called exogenous infection. This has drawn considerable attention and research efforts intended to better characterize the contributory risk of each of the following factors: instrument design, reprocessing measures (eg, manual and automated cleaning), surveillance strategies for detecting instrument contamination, and other quality metrics.

Worldwide an increasing number of duodenoscope-associated outbreaks are reported. The high prevalence rate of contaminated duodenoscopes puts patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) at risk of exogenous transmission of microorganisms. The contributing factors of the duodenoscope design to contamination are not well understood. This paper reports on the investigation after the outbreak of a multidrug-resistant Klebsiella pneumoniae (MRKP) related to 2 Olympus TJF-Q180V duodenoscopes.

Although ERCP is clearly a major technologic advancement in the management of pancreaticobiliary disorders, it has historically been associated with a risk of infection as a potential procedure-related adverse event. Conventional wisdom has ascribed the risk of infection to stents and stones in the obstructed pancreaticobiliary tree. Now, with reported outbreaks of multidrug-resistant bacterial infections in patients undergoing ERCP and duodenoscopy in medical centers around the world,1-5 attention has turned to the duodenoscope as the vector of infection.

A report by Democrats on the U.S. Senate’s health committee issued this week blames hospitals, medical device companies and the FDA for the deadly outbreaks of so-called “superbug” infections linked to duodenoscopes. The devices are used for a procedure called endoscopic retrograde cholangiopancreatography, in which a reusable tube-like camera is inserted into the throat of a patient. More than 500,000 ERCPs using the devices are performed in the U.S. annually. Hospitals in Connecticut, Virginia, California and Washington state all reported superbug outbreaks in February and March 2014, some of which led ...

Authors: Ha J, Son BK Abstract A duodenoscope has a very complex structure that contains many small parts which make reprocessing more challenging. The difficulty in cleaning duodenoscopes contributes to a higher risk of infection than that of conventional gastrointestinal endoscopes. However, a duodenoscope shares similar disinfection process with other gastrointestinal endoscopes. Recent outbreaks of carbapenem-resistant Enterobacteriaceae (CRE) infections associated with duodenoscopes used for endoscopic retrograde cholangiopancreatography procedures have raised many concerns worldwide. Duodenoscope-associated i...

The FDA today ordered a trio of Japanese duodenoscope makers to run post-market surveillance studies to evaluate how the devices are reprocessed in real-world conditions, after a deadly rash of so-called “superbug” outbreaks this year were linked to the devices. The string of deadly infections were attributed to duodenoscopes made by Olympus (TYO:7733),  Fujifilm Holdings (TSE:4901) and Hoya‘s (TYO:7741) Pentax subsidiary. The devices are used for a procedure called endoscopic retrograde cholangiopancreatography, in which a reusable tube-like cam...

In recent months, medical reports and intense media interest have highlighted the problem of patient-to-patient transmission of carbapenem-resistant Enterobacteriaciae (CRE) and other multidrug-resistant organisms (MDRO) by contaminated duodenoscopes during ERCP. Details of a non-CRE MDRO outbreak were recently published by the staff of the King County Health Department and the Virginia Mason Medical Center (VMMC) in Seattle, Washington.1 In this issue of Gastrointestinal Endoscopy, Ross and colleagues of VMMC outline their institutional response to the outbreak and the results of their practice of universal duodenoscope c...
