Scope Infection Lawsuit Overview

Scope infection lawsuits are being investigated for individuals who developed serious bacterial infections after undergoing routine procedures like a colonoscopy, endoscopy, ERCP, or bronchoscopy. Although these are standard diagnostic or treatment procedures, where patients expect sterile conditions, devastating infections have been linked to design problems associated with certain types of medical scopes widely used by medical providers.

Lawsuits focus on the manufacturers of reusable endoscopes and duodenoscopes, alleging that the scope design prevents the device from being fully sterilized between patients. Because these scopes contain internal channels and mechanical components that may trap bacteria, the devices may remain contaminated and transfer harmful bacteria from one patient to another, even when hospitals follow proper cleaning protocols.

As more patients learn about these contamination problems, there are now a growing number of colonoscopy infection lawsuits, endoscopy infection lawsuits, ERCP infection lawsuits and other claims being investigated by our lawyers.

Many of these claims involve Olympus scope lawsuits, but potential claims are also being investigated for other manufacturers that designed and sold reusable scopes without ensuring they could be safely disinfected or without adequately warning hospitals of the risks.

The scope infection lawyers at Saiontz & Kirk are pursuing financial compensation for individuals who developed serious infections after a scope procedure, including those who required hospitalization, IV antibiotics, or suffered long-term complications. These cases seek to hold manufacturers accountable for placing defective medical devices into widespread use.

Procedures That Use Scopes

Medical scopes are commonly used during routine procedures, including:

• Colonoscopy, used to screen for colon cancer and intestinal conditions
• Upper endoscopy (EGD), used to examine the esophagus and stomach
• Ureterorenoscopes, to treat and diagnose urinary tract problems like kidney stones
• ERCP procedures, used to treat bile duct and pancreatic conditions
• Bronchoscopy, to examine the lungs and airways
• Laparoscopes, for minimally invasive surgeries

These procedures are performed millions of times each year and are generally considered safe when the medical devices are fully sterilized between patients. However, when design defects prevent the proper sterilization, reusable scopes can cause devastating and life-threatening infections.

Why Are Surgical Scopes Reused?

Unlike disposable instruments, many surgical scopes are designed to be reused on multiple patients due to their high cost. After each procedure, hospitals must clean and disinfect the device through a process known as reprocessing, which is intended to remove biological material before the scope is used again.

However, lawsuits allege that certain scope designs may prevent complete sterilization, increasing the risk that bacteria can remain inside the device and be transferred between patients.

Why Olympus Scopes Carry Infection Risks

Certain Olympus scopes carry infection risks because they are reused medical devices that come into direct contact with internal areas of the body, including the digestive tract, bile ducts, and lungs. During procedures, these devices are exposed to bodily fluids, bacteria, and biological material from one patient before being cleaned and used again on someone else.

Unlike simple surgical tools, many endoscopes and duodenoscopes contain complex internal structures where contamination can become trapped and difficult to remove during cleaning.

High-Risk Areas Where Bacteria Can Become Trapped

Lawsuits and investigations have identified several parts of Olympus scopes that are particularly prone to retaining residue and bacteria, including:

• Elevator mechanisms, which contain small moving parts and tight crevices used during ERCP procedures
• Narrow internal channels, where fluids and biological material can collect during use
• Hinges and joints, which may trap debris in hard-to-clean areas
• Sealed internal components, which cannot be fully accessed or visually inspected during cleaning
• Distal ends and tip components, where contact with bodily fluids is most direct

Because these areas are difficult to fully clean and disinfect, bacteria from a prior patient may remain inside the device, even after reprocessing. As a result, contaminated scopes may transfer bacteria directly into another patient’s body during a later procedure, leading to serious infections.

Lawsuits allege that manufacturers were aware of these risks and continued selling devices that could not be reliably sterilized, increasing the likelihood that infections could spread between patients.

Scope Infections and Injuries

Olympus scope lawsuits involve individuals who developed serious infections after procedures such as colonoscopy, endoscopy, ERCP, or bronchoscopy.

Serious Infections Reported in Lawsuits

• Sepsis: A life-threatening condition where bacteria spread through the bloodstream, triggering widespread inflammation and organ dysfunction.
• Bloodstream infections (Bacteremia): Occur when bacteria introduced during a procedure enter the blood directly, allowing infection to spread rapidly throughout the body.
• Carbapenem-resistant Enterobacteriaceae (CRE): A highly dangerous, drug-resistant bacteria often linked to contaminated duodenoscopes, which can be extremely difficult to treat.
• E. coli infections: Normally found in the digestive tract, but can cause serious illness if introduced into sterile areas like the bloodstream or bile ducts during a procedure.
• Pneumonia: May develop when bacteria are introduced into the lungs during bronchoscopy or spread from systemic infection.
• Organ failure: Severe infections can damage vital organs such as the kidneys, liver, or lungs, especially when sepsis develops.
• Extended hospitalization: Many patients require prolonged hospital stays due to severe infections and complications following a procedure.
• Need for IV antibiotics: Serious infections often require aggressive treatment with intravenous antibiotics to control the spread of bacteria.
• Long-term complications: Some patients experience lasting health problems, including chronic pain, fatigue, or organ damage after infection.
• Exposure to blood-borne infections, including HIV or tuberculosis: Improperly sterilized devices may carry contaminated biological material, creating a risk of exposure to serious infectious diseases.
• Wrongful death: In severe cases, infections linked to contaminated scopes have resulted in fatal complications.

When Do Symptoms of Infection Appear?

Symptoms of infection after a contaminated scope procedure may develop within 24 to 48 hours, but in some cases may take several days or even weeks to appear. Common warning signs of infection may include:

• Fever and chills
• Severe abdominal pain
• Rapid heart rate
• Low blood pressure
• Nausea or vomiting
• Difficulty breathing
• Extreme fatigue or weakness

In some cases, infections can progress quickly and become life-threatening, requiring emergency medical treatment.

Olympus Scope Lawsuits

Many medical scope infection lawsuits focus on Olympus Corporation, whose reusable duodenoscopes and endoscopic devices have been widely used in hospitals across the United States.

These devices have been linked to multiple infection outbreaks, including cases involving drug-resistant bacteria such as CRE, which have resulted in serious injuries and deaths. In some instances, hospitals were forced to notify hundreds of patients that they may have been exposed to contaminated scopes following routine procedures.

FDA Warnings About Olympus Scope Infection Risks

Federal regulators have raised ongoing concerns about the safety of Olympus devices and the company’s compliance with quality and reporting requirements.

In June 2025, the U.S. Food and Drug Administration issued import alerts blocking dozens of Olympus medical devices from entering the United States, including certain endoscopes and reprocessing equipment. The action targeted products manufactured at an Olympus facility in Japan due to continued violations of federal safety regulations.

The FDA previously issued a November 2022 Olympus warning letter identifying serious problems at the same facility, including failures to properly test device designs, validate manufacturing processes, and document safety procedures. According to the FDA, Olympus and its subsidiary failed to:

• Properly test and validate device designs before distribution
• Ensure manufacturing processes consistently produced safe devices
• Maintain adequate systems for reporting device problems and adverse events

Regulators warned that these failures could allow contaminated devices to remain in use and delay corrective actions needed to protect patients.

Regulatory investigations, safety communications, and recalls have placed Olympus at the center of ongoing scope infection litigation.

Plaintiffs allege that despite known risks associated with reusable scope designs and contamination concerns, Olympus continued to market and distribute these devices for widespread use in hospitals.

While many lawsuits involve Olympus devices, claims may also be filed against other manufacturers if similar products contributed to infection outbreaks.

Allegations Raised in Contaminated Scope Lawsuits

Contaminated scope infection lawsuits focus on whether manufacturers can be held legally responsible for placing unsafe medical devices into use.

Plaintiffs claim that certain reusable scopes were not designed or supported in a way that allowed them to be safely used on multiple patients.

Common allegations raised in medical scope lawsuits include:

• Defective design, making the devices difficult or impossible to fully sterilize
• Failure to warn, by not adequately informing hospitals and doctors of infection risks
• Inadequate cleaning instructions, which did not effectively eliminate contamination
• Continued sale of unsafe devices, despite knowledge of infection outbreaks and risks

As a result of these alleged failures, patients may have been exposed to dangerous infections during routine procedures where they reasonably expected sterile conditions.

Compensation for Scope Infection Injuries

Individuals who file a Olympus scope infection lawsuit may be entitled to financial compensation for injuries and losses related to their infection. Compensation may include:

• Medical expenses and hospital bills
• Costs of ongoing treatment or long-term care
• Lost wages or reduced earning capacity
• Pain and suffering
• Long-term health complications
• Reduced quality of life
• Wrongful death damages for surviving family members

The amount of compensation will depend on factors such as the severity of the infection, the treatment required, and the long-term impact on the individual’s health.

If you or a loved one developed a serious infection after a colonoscopy, endoscopy, ERCP, or bronchoscopy, you may be eligible to pursue a Olympus scope infection lawsuit settlement.
