ERCP — endoscopic retrograde cholangiopancreatography — carries the highest infection risk of any routine endoscopic procedure. It is the one procedure that specifically requires a duodenoscope, and the duodenoscope's elevator mechanism has been traced directly to deadly superbug outbreaks at major U.S. hospitals.
If you had an ERCP and later developed a drug-resistant infection — whether months ago or years ago — a contaminated Olympus scope may be the reason. Understanding the risk, the timeline, and your rights starts here.
ERCP is used to diagnose and treat problems in the bile ducts and pancreas — gallstones stuck in the bile duct, blockages, tumors, and chronic pancreatitis. Roughly 700,000 ERCP procedures are performed in the United States each year, usually on patients who are already quite sick. The procedure requires a specialized scope called a duodenoscope.
A duodenoscope is passed through the mouth, down the esophagus, through the stomach, and into the first part of the small intestine (the duodenum). From there, the doctor can steer instruments sideways into the bile duct and pancreatic duct — but only because of a tiny hinged lever at the tip of the scope called the elevator mechanism.
The elevator mechanism is essential to the procedure. Without it, doctors could not guide catheters and wires into the right ducts. Unfortunately, it is also the single most contamination-prone part of any reusable endoscope.
The elevator mechanism has moving parts, tiny crevices, and a small enclosed channel that opens only when the lever is raised. During an ERCP, blood, bile, tissue, and bacteria from the patient's gut work their way into these crevices.
Standard cleaning pushes brushes through the main channel and then soaks the scope in liquid disinfectant. Neither step can reliably reach every surface of the elevator. Research has repeatedly shown bacteria still present in the elevator channel after full reprocessing — even when Olympus's own cleaning instructions are followed exactly. Read more about the design defect at the heart of the crisis.
ERCP is not a routine screening procedure like colonoscopy. It is typically ordered for patients with serious problems — gallstones causing obstruction, suspected pancreatic cancer, severe pancreatitis, or biliary infections. That means ERCP patients are already medically vulnerable when a contaminated scope transmits a drug-resistant infection, and the results can be devastating.
This is not a theoretical problem. Contaminated ERCP duodenoscopes have been traced to specific outbreaks at some of the most respected hospitals in the United States. Each outbreak was investigated by hospital infection-control teams, the CDC, and the FDA — and in each case, the scope itself was identified as the source.
Virginia Mason in Seattle traced at least 39 patient infections to contaminated Olympus duodenoscopes used in ERCP procedures. Eighteen of those patients died. Investigations found that the scopes had been cleaned according to manufacturer instructions, but bacteria were still present in the elevator channel. Virginia Mason went on to adopt more aggressive sterilization protocols but could not fully eliminate the risk until the basic scope design changed.

UCLA publicly announced that 179 patients may have been exposed to CRE superbugs through two contaminated Olympus duodenoscopes. Seven patients were confirmed infected. Two died. The scopes were pulled from service and UCLA switched to a more aggressive sterilization method that is not standard for most hospitals. The announcement made national news and became a turning point in public awareness of the scope contamination crisis.

Within weeks of the UCLA announcement, Cedars-Sinai disclosed that approximately 68 patients had been exposed to CRE through an Olympus duodenoscope used for ERCP. Several patients were confirmed infected. Like UCLA and Virginia Mason, the hospital had been following Olympus's cleaning instructions — the contamination came from the scope, not the cleaning.

These are only the outbreaks that became public. The FDA's MAUDE database contains many more reports of infections linked to ERCP duodenoscopes — reports filed by hospitals, patients, and doctors over more than a decade. For the federal response to these outbreaks, see our page on FDA warnings and recalls.
CRE stands for carbapenem-resistant Enterobacteriaceae. Enterobacteriaceae is a family of bacteria that includes common gut germs such as E. coli and Klebsiella. "Carbapenem-resistant" means those bacteria have evolved to survive carbapenems — a class of antibiotics doctors use when nothing else will work.
When a CRE infection takes hold, many of the medications doctors would normally reach for simply don't work. The patient's immune system is often the main thing standing between the infection and a fatal outcome.
The CDC has classified CRE as an urgent threat — the highest category in its antibiotic resistance threat ranking — because of how fast CRE can kill and how few treatment options exist.
The CDC estimates that CRE bloodstream infections can kill up to 50% of the people who get them. Not every CRE infection reaches the bloodstream — but when it does, the mortality is comparable to some of the deadliest diseases we track.
ERCP patients are often already sick — fighting gallstones, cancer, pancreatitis, or biliary infections. Layering a CRE infection on top of that weakens the patient's ability to fight back. Many patients end up hospitalized for weeks, require multiple surgeries, and face months or years of recovery. For the signs to watch for after an ERCP, see infection symptoms.
The story of ERCP scope infections spans more than a decade of warnings, outbreaks, recalls, and regulatory action. Understanding the timeline matters for patients, because it shows how long the problem was known — and that is part of what supports a case today.

Answers to the questions we hear most often from ERCP patients and their families.
ERCP is the one endoscopic procedure that uses a duodenoscope. A duodenoscope has an elevator mechanism at its tip — a small lever needed to steer instruments into the bile duct and pancreatic duct. That elevator is the part of the scope the FDA has identified as the root cause of contamination. It traps biological material that standard cleaning cannot reach. No other endoscopic procedure uses this type of scope, which is why ERCP stands apart as the highest-risk procedure.
Possibly. Every state has a time limit for filing injury and product liability cases, but those limits often start on the date you discovered — or reasonably should have discovered — that a contaminated scope caused your infection. Many patients were never told the scope was the source. If you had an ERCP since 2012 and developed an unexplained serious infection afterward, it is worth a free case review before assuming the time has passed. The only way to know for sure is to talk to an attorney about your specific situation.
That's normal — patients are rarely told what brand or model of scope was used. Hospitals keep records of which scope was used in which procedure, and those records can be obtained as part of a case. If a case moves forward, your attorney can work with a medical-legal expert (in our firm, that is Herb Borroto, M.D., J.D.) to pull and review those records. Olympus was the dominant duodenoscope maker in the United States during the outbreak years, so there is a reasonable chance the scope was an Olympus product.
The most commonly documented infections from contaminated ERCP scopes are caused by carbapenem-resistant Enterobacteriaceae (CRE) — sometimes called superbugs — including carbapenem-resistant E. coli and Klebsiella. Other reported pathogens include Pseudomonas aeruginosa, multidrug-resistant Acinetobacter, and extended-spectrum beta-lactamase (ESBL) producing bacteria. Sepsis, cholangitis, and bacteremia following an ERCP are the kinds of diagnoses that should trigger a closer look at the scope. Our team can help review your records to see if your infection pattern fits.
