Endoscope/ Duodenoscope Superbug Infection Lawsuits

Connect with an attorney

When you have a medical procedure, you should be able to count on the medical devices and equipment used in the procedure to be sterilized and safe for use. Unfortunately, at least 2 million people become infected with antibiotic resistant bacteria each year in the U.S., according to the CDC, some of whom fall ill after undergoing a medical procedure.

Motley Rice medical device attorneys are reviewing potential cases involving patients who became seriously ill following a medical procedure involving a duodenoscope. The FDA has reported that the complex design of duodenoscopes may impede effective reprocessing, or the cleaning, disinfecting and sterilizing of these types of scopes.

If you or a loved one had an endoscopy and suffered from infections and serious complications, including pneumonia or the “superbug”, or passed away from serious illness, you may have a potential claim. You may call medical device attorney Carmen Scott at 1-800-768-4026 or email for more information.

What is a Duodenoscope?

Duodenoscopes are flexible, lighted tools that are used during potentially lifesaving procedures to diagnose and treat problems in the pancreas and bile ducts. The bendable tubes are threaded through the mouth, throat and stomach into the top of the small intestine and provide visuals, used during endoscopic retrograde cholangiopancreatography (ERCP).

Problems reported with Duodenoscopes

According to the FDA, approximately 500,000 procedures are done each year in the United States with duodenoscopes. Duodenoscopes are critical to diagnosing and treating diseases, however if the many small parts are not thoroughly cleaned and disinfected the device may cause potentially fatal, patient-to-patient infections.

The infections that the scope have been reported to spread are considered antibiotic-resistant superbugs.

According to a report by the FDA, approximately 300 to 350 patients at 41 medical facilities in the U.S. and around the world were infected or exposed to tainted gastrointestinal scopes from Jan. 1, 2010 to Oct. 31, 2015. The U.S. Senate conducted its own investigation and released a report in January 2016 that found 250 patients were infected by tainted scopes at 25 medical facilities in the U.S. and Europe between 2012 and 2015.

Pentax Duodenoscope Recall

After being notified by the CDC in 2013 that design defects in certain endoscope and duodenoscope products may contribute to high multi-drug resistant bacteria rates in patients, despite cleaning recommendations being followed, the FDA began working with manufacturers to modify the devices and enhance safety. In February 2018, one such manufacturer Pentax issued a voluntary recall of its model ED-3490TK duodenoscope devices in order to make necessary design adjustments and update maintenance recommendations. The FDA approved the modifications and updated labeling for the product on Feb. 7, 2018.

Olympus Duodenoscope Background

In March 2014, the FDA sent a letter to Olympus highlighting a design change that it believed to contribute to sanitary issues and ordered it to obtain FDA clearance within thirty business days. 

In February 2015, the FDA released a safety communication on duodenoscopes stating that the manufacturer-recommended cleaning procedures may not be sufficient to properly sterilize the instruments due to the design of the scope. That same year, the FDA was notified that Olympus Corporation failed to alert regulators that patients were developing superbug infections (sometimes referred to as CRE or carbapenem-resistent enterobacteriaceae) following procedures using the company’s duodenoscope, a type of endoscope.

Medical device manufacturers are required by the FDA to report serious problems within 30 days of learning about them. Olympus waited three years to report these infections. Hospital locations that have been implicated in duodenoscope-related outbreaks include UCLA’s Ronald Reagan Medical Center, Cedar-Sinai Medical Center, Virginia Mason Medical Center in Seattle, Advocate Lutheran General Hospital (suburban Chicago, IL), and UPMC Presbyterian (Pittsburgh, PA) and others.

In January 2016, Olympus recalled its original model duodenoscope.
