Colonoscopy & Endoscopy Infection Lawsuit

If you or a loved one developed a serious infection after a colonoscopy, ERCP, or other endoscopic procedure, the source may not have been bad luck — it may have been a contaminated medical scope. Hundreds of patients across the United States have been sickened, and dozens have died, from infections traced to flexible endoscopes that hospitals could not properly clean. Federal prosecutors, the FDA, and a U.S. Senate investigation have all confirmed the problem. Lawsuits against the device manufacturers are still being filed in 2026.

What Actually Happens Inside a Contaminated Scope

The most documented infections are linked to a specialized device called a duodenoscope, used during ERCP procedures to examine the bile and pancreatic ducts. These scopes have a tiny moving part at the tip — the "elevator mechanism" — with crevices that trap bacteria, biofilm, and patient tissue. Standard hospital cleaning protocols frequently fail to reach those surfaces.

Other endoscopes used in colonoscopies, upper-GI exams, and bronchoscopies have also transmitted infections, though less often. Documented organisms passed from patient to patient include:

• Carbapenem-resistant Enterobacteriaceae (CRE) — a "superbug" resistant to last-resort antibiotics
• Drug-resistant E. coli and Klebsiella
• Multidrug-resistant Pseudomonas aeruginosa
• Hepatitis C, hepatitis B, and HIV — confirmed in multiple endoscopy transmission cases

In the largest published study to date, Johns Hopkins researchers found post-procedure infection rates as high as 45 per 1,000 colonoscopies and 59 per 1,000 upper endoscopies for patients who had been hospitalized in the prior 30 days — far higher than the rates patients are typically told about before signing consent.

The Devices and Manufacturers Involved

Three companies dominate the U.S. duodenoscope and endoscope market, and all three have faced regulatory action:

• Olympus Corporation — TJF-Q180V (recalled and redesigned), TJF-Q190V, TJF-Q290V, and TJF-Q170V duodenoscopes; plus various bronchoscopes and laparoscopes covered by a 2025 FDA import alert. Olympus has historically held roughly 85% of the U.S. duodenoscope market (U.S. Senate HELP Committee, 2016).
• PENTAX Medical — ED-3490TK and other duodenoscope models, with a documented defect at the distal-cap-to-scope joint that allowed bacteria and fluids to seep into the device.
• Fujifilm — ED-530XT duodenoscope, voluntarily recalled in July 2017 after the FDA cited the company for failing to report adverse events.

Major Outbreaks That Triggered the Litigation

• Virginia Mason Medical Center (Seattle, 2012–2014) — at least 32 patients infected with antibiotic-resistant E. coli (later expanded to 39), with 11 deaths attributable to the infection. In 2017 a jury ordered Olympus to pay $6.6 million on a failure-to-warn claim and also held the hospital partly negligent, ordering it to pay $1 million to the family of patient Richard Bigler.
• UCLA Ronald Reagan Medical Center (Los Angeles, 2014–2015) — 179 patients exposed to CRE, 7 confirmed infections, 2 deaths. The outbreak became national news and prompted the first FDA safety communication on duodenoscopes.
• Cedars-Sinai Medical Center (Los Angeles, 2014–2015) — 71 patients notified of CRE exposure, 4 confirmed infections.
• Neosho Memorial Regional Medical Center (Kansas, 2013) — 240 colonoscopy patients notified of possible HIV and hepatitis exposure after a reprocessing failure.
• Vanderbilt University Medical Center (Tennessee, October 2024) — endoscopy patients warned of potential HIV, hepatitis B, and hepatitis C exposure after a reprocessing error involving how a cleaning solution was administered through the scope. The hospital said fewer than 4% of endoscopy patients over the prior six months were affected.

A 2016 U.S. Senate investigation concluded that at least 25 outbreaks worldwide had sickened more than 250 patients, and a 2020 review in The Lancet eClinicalMedicine identified at least 24 multidrug-resistant outbreak clusters tied to ERCP scopes, involving 490 patient infections between 2008 and 2018.

Why This Is Still a Live Lawsuit in 2026

Two recent regulatory actions have brought new cases forward:

1. June 2025 — FDA Import Alert 89-04. The FDA blocked entry of certain Olympus medical devices manufactured at the Aizu facility in Fukushima, Japan, citing "outstanding Quality System regulation violations."
2. October 17, 2025 — Olympus Urgent Field Safety Notice. Olympus disclosed 2 deaths and 5 serious injuries from 2024–2025 linked to its TJF-Q190V, TJF-Q290V, and TJF-Q170V duodenoscopes. Hospitals were instructed to inspect scope tips under 10x magnification, because surface defects trapping bacteria are not visible to the naked eye.

In December 2018, Olympus Medical Systems Corp. pleaded guilty in U.S. federal court to three counts of distributing misbranded medical devices, paying $85 million in fines and forfeiture for failing to report European outbreaks involving roughly 30 patients infected with E. coli and drug-resistant Pseudomonas. Hisao Yabe, a former senior Olympus executive, also pleaded guilty and was sentenced to probation in 2019. Pentax later paid $43 million in 2020 under a deferred prosecution agreement to resolve its own federal investigation. These admissions are central to current product-liability claims because they establish what the manufacturers knew, and when.

Symptoms to Watch For

Infections from a contaminated scope typically appear within 30 days of the procedure — most commonly between 3 and 14 days. Warning signs include:

• Fever, chills, or night sweats
• Severe or unusual abdominal pain
• Persistent rectal bleeding or bloody diarrhea
• Jaundice (yellow skin or eyes)
• Confusion, rapid heart rate, low blood pressure, or difficulty breathing — possible signs of sepsis

Any patient hospitalized for a serious infection within a month of an endoscopic procedure should ask their doctor for a culture and confirm whether the scope make and model has been associated with outbreaks.

Who May Qualify to File a Claim

You may be eligible if you can answer "yes" to most of the following:

• You or a family member underwent a colonoscopy, ERCP, EGD, bronchoscopy, or similar endoscopic procedure
• A serious infection developed within roughly 30 days afterward
• Treatment required IV antibiotics, hospitalization, surgery, or ICU care
• You did not have the same infection in the year before the procedure

Family members of patients who died from procedure-linked infections may also pursue wrongful-death claims.

You will need: the procedure date and facility, hospital records confirming the infection (including any culture results), itemized medical bills, and any patient-notification letter the hospital may have sent.

What Compensation Looks Like

There is no consolidated MDL for these cases as of 2026. Lawsuits proceed individually in state and federal court, often naming both the device manufacturer and the hospital. Recoverable damages typically include:

• Past and future medical expenses
• Lost wages and lost earning capacity
• Pain and suffering
• Loss of companionship for spouses and family
• Funeral costs and survivor losses in wrongful-death cases
• Punitive damages, where the manufacturer's prior knowledge can be shown

Most patient and family settlements have been resolved confidentially, so "average payout" figures circulating online are unreliable. The only public benchmarks are the $6.6 million Virginia Mason jury verdict and the criminal penalties paid by Olympus and Pentax.

How Long Do You Have to File

Statute-of-limitations rules vary by state — generally between one and six years for medical-malpractice and product-liability claims. Most states apply a discovery rule that starts the clock when a patient learned (or reasonably should have learned) that a defective device or improper cleaning caused the infection. Patients who only recently connected their illness to an FDA recall, an Olympus safety notice, or a hospital-notification letter may still have time, even for procedures performed years earlier.

Wrongful-death claims have their own, often shorter, deadlines. The only safe answer is to have a lawyer evaluate your specific dates as soon as possible.

Frequently Asked Questions

I had a colonoscopy and got sick — could it be related? Possibly, especially if symptoms appeared within 30 days, you required IV antibiotics or hospitalization, or your cultures grew CRE, drug-resistant E. coli, Klebsiella, or Pseudomonas.

Is the hospital liable, the doctor, or the device maker? Potentially all three. Hospitals can be sued for negligent reprocessing, doctors for malpractice, and manufacturers for design defects and failure to warn. The Virginia Mason verdict allocated fault between the hospital and Olympus.

What does it cost to file a lawsuit? Nothing upfront. These cases are taken on contingency — the law firm is paid only if you recover.

Is it too late if my procedure was years ago? Not necessarily. The discovery rule applies in most states, and recent FDA actions in 2025 have been used to argue the clock should restart for patients who only now learned about the device link. A free case review is the only way to know.

What if I don't know which scope was used? The hospital is required to keep records identifying the device serial number and reprocessing logs. Counsel can subpoena those records as part of the case.
