Olympus, the manufacturer of the TJF-Q180V duodenoscope, has issued new, validated instructions for reprocessing this particular model, as part of the response to recent reports of a possible association between multidrug-resistant bacterial infections and improperly processed duodenoscopes, according to the Food and Drug Administration.

The new instructions, which replace the manual reprocessing instructions included in the original labeling, and validation data have been reviewed by the FDA as part of its ongoing review of the device. The agency “recommends that any facilities that are using Olympus’ TJF-Q180V duodenoscope train staff on the new instructions and implement them as soon as possible,” according to an FDA statement . The instructions are provided in letters sent by Olympus to health care and other facilities that use this particular model.

“Key changes” have been made to the procedures for precleaning, manual cleaning, and manual high-level disinfection reprocessing procedures, the FDA said.

The TJF-Q180 V duodenoscope was the model used in four patients who had undergone an endoscopic retrograde cholangiopancreatography (ERCP) procedure between August 2014 and January 2015 with the same duodenoscope at Cedars-Sinai Medical Center in Los Angeles and had been infected with carbapenem-resistant Enterobacteriaceae (CRE). This outbreak was announced by the medical center in early March in a statement that said the infections occurred “despite the fact that Cedars-Sinai meticulously followed the disinfection procedure for duodenoscopes” recommended in instructions provided by Olympus and the FDA.

In February, the FDA first announced that the agency had received reports of multidrug-resistant bacterial infections in patients who had undergone ERCP procedures with duodenoscopes, despite proper cleaning and disinfection of the devices and that the “complex design of ERCP endoscopes (also called duodenoscopes) may impede effective reprocessing.”

In the latest statement, the FDA said it “is closely monitoring the possible association between reprocessed duodenoscopes and the transmission of infectious agents,” including multidrug-resistant bacterial infections caused by CRE. If they are not properly reprocessed, the statement adds, “residual body fluids and organic debris may remain in microscopic crevices of the device following an attempted cleaning and high-level disinfection. If these residual fluids contain microbial contamination, subsequent patients may be exposed to serious infections.”

Adverse events associated with duodenoscopes should be reported to the FDA’s MedWatch Program at 800-332-1088 or www.accessdata.fda.gov/scripts/medwatch.
