Infections from contaminated endoscopes can appear days, weeks, or even months after a procedure. Recognizing the warning signs early can be the difference between a treatable infection and a life-threatening emergency.
If you or a loved one developed any of the symptoms described on this page following a colonoscopy, ERCP, bronchoscopy, gastroscopy, or other endoscopic procedure, you may have been exposed to a contaminated Olympus scope. Contact us for a free, confidential case review.
Infection symptoms from a contaminated endoscope typically appear within the first few days following a procedure, though they may take longer to develop. If you experience any of the following symptoms after a colonoscopy, ERCP, bronchoscopy, gastroscopy, or other scope procedure, seek immediate medical attention.
A temperature of 100.4°F (38°C) or higher within days of an endoscopic procedure is a significant red flag that should never be ignored. Fever is the body's primary response to infection and often the first sign that bacteria from a contaminated scope have entered your system.
Uncontrollable shaking, known medically as rigors, is a hallmark sign of a serious bacterial infection. When the body detects dangerous pathogens in the bloodstream, it triggers violent shivering episodes. Rigors following an endoscopic procedure are a medical emergency.
Severe abdominal pain or cramping is especially common after ERCP and colonoscopy procedures performed with contaminated scopes. The pain may be localized or widespread, and often intensifies rather than improves in the days following the procedure.
Persistent nausea and vomiting that develop or worsen after an endoscopic procedure can indicate a systemic infection. While mild nausea may occur from anesthesia, vomiting that continues beyond 24 hours warrants immediate medical evaluation.
Diarrhea following an endoscopic procedure, especially if it contains blood, is a serious warning sign. Bloody diarrhea after a colonoscopy or other scope procedure can indicate an active bacterial infection transmitted from the contaminated device to the patient's gastrointestinal tract.
Pain, redness, swelling, or unusual discharge at the insertion point of the endoscope can indicate a localized infection. Any warmth, tenderness, or pus-like drainage from the site where the scope was inserted should be evaluated by a physician immediately.
Overwhelming fatigue and malaise that persist or worsen in the days after an endoscopic procedure may signal the body is fighting a serious infection. This is not the mild tiredness that may follow anesthesia — it is a deep, debilitating exhaustion that does not improve with rest.
Redness, warmth, or swelling around the area where the endoscope was inserted may indicate a local or spreading infection. Any discharge, especially if it is discolored or foul-smelling, should be treated as an urgent medical concern requiring evaluation.
Many patients who develop infections after endoscopic procedures initially assume their symptoms are "normal" post-procedure side effects. They are not. While mild discomfort or grogginess from anesthesia may be expected, fever, chills, severe abdominal pain, bloody diarrhea, and other infection symptoms are never normal after an endoscopic procedure.
Dismissing these symptoms as routine can allow a treatable infection to progress into sepsis, organ failure, or death. If you experience any of these symptoms within days, weeks, or even months of an endoscopic procedure, go to the emergency room immediately and tell your doctor about the recent endoscopy.
Early detection and treatment can save your life. Do not wait. Do not assume it will pass.
When infections from contaminated endoscopes are not caught early, they can rapidly escalate into severe, life-threatening medical emergencies. These complications require intensive medical intervention and can result in permanent injury or death. Understanding these risks underscores why early symptom recognition is so critical.
Sepsis occurs when bacteria from a contaminated endoscope enter the bloodstream, triggering a massive inflammatory response throughout the body. This is one of the most dangerous complications of an endoscope-related infection and can progress from initial symptoms to organ failure and death within hours.
Warning signs of sepsis include:
When an infection from a contaminated endoscope overwhelms the body, vital organs can begin to shut down. The kidneys, liver, and lungs are particularly vulnerable. Organ failure often occurs as a complication of sepsis, when the body's inflammatory response causes widespread tissue damage.
Patients who experience organ failure from a scope-related infection often require:
Contaminated Olympus endoscopes have been linked to the transmission of CRE (carbapenem-resistant Enterobacteriaceae) and other antibiotic-resistant "superbugs." These organisms do not respond to standard antibiotics — including carbapenems, which are considered the antibiotics of last resort.
Treatment for antibiotic-resistant infections may require:
Many patients who contract infections from contaminated endoscopes face weeks or months of hospital care. What should have been a routine outpatient procedure can result in an extended stay in the ICU, multiple surgeries to address the infection and its complications, and a long, painful road to recovery.
Prolonged hospitalization carries its own risks, including secondary infections acquired in the hospital, blood clots, muscle wasting, psychological trauma, and massive financial burdens from medical bills, lost wages, and ongoing care needs. For many patients, life is never the same after a contaminated scope infection.
In the most severe cases, infections transmitted through contaminated endoscopes have been fatal. Patients who are elderly, immunocompromised, or already medically fragile are at the highest risk. Deaths from contaminated scope infections are particularly tragic because the patients were seeking medical help — not expecting to receive a fatal infection from the very instrument used to diagnose or treat them.
Wrongful death claims arising from contaminated endoscope infections allow surviving family members to seek accountability from Olympus and the responsible healthcare facilities. If you lost a loved one to an infection following an endoscopic procedure, The Alvarez Law Firm can help you understand your legal options.
Beyond the primary infection, patients may develop a cascade of secondary medical problems that compound their suffering and extend their recovery. Contaminated scope infections can trigger complications that affect virtually every system in the body.
Contaminated Olympus endoscopes have been linked to the transmission of several particularly dangerous organisms. These bacteria are dangerous precisely because they resist standard antibiotic treatments, making infections from contaminated scopes far more difficult to treat than ordinary infections.
CRE is considered one of the most urgent public health threats by the CDC. These bacteria are resistant to carbapenems — the most powerful class of antibiotics available — leaving doctors with extremely limited treatment options. CRE infections carry a mortality rate of 40-50% for bloodstream infections, making them among the deadliest healthcare-associated infections.
CRE has been directly linked to contaminated Olympus duodenoscopes in multiple high-profile outbreaks at hospitals across the United States. In these outbreaks, patients who underwent routine ERCP procedures contracted CRE infections because the scopes could not be adequately cleaned between patients, despite hospitals following Olympus's own reprocessing instructions.
CRE is classified as an "urgent threat" by the CDC because it resists nearly all available antibiotics and can spread its resistance genes to other bacteria.
Pseudomonas aeruginosa is an opportunistic bacterium commonly found in contaminated bronchoscopes and other endoscopic equipment. It thrives in moist environments, making the internal channels of endoscopes an ideal breeding ground. This organism is naturally resistant to many antibiotics, and multidrug-resistant strains are increasingly common.
Pseudomonas infections from contaminated scopes can cause pneumonia, bloodstream infections, urinary tract infections, and wound infections. In immunocompromised patients or those with underlying lung disease, Pseudomonas infections can be particularly aggressive and difficult to eradicate. Treatment often requires prolonged courses of IV antibiotics, and recurrent infections are common.
Pseudomonas can form biofilms inside endoscope channels, making it virtually impossible to remove through standard cleaning procedures.
E. coli is one of the most common organisms found in contaminated colonoscopes and other gastrointestinal endoscopes. When these scopes are not adequately cleaned between patients, E. coli from one patient's intestinal tract can be transmitted to the next patient. While many strains of E. coli are harmless, certain strains that proliferate in the contaminated environment of a poorly cleaned scope can cause severe illness.
E. coli infections from contaminated scopes can cause severe urinary tract infections, bloodstream infections (bacteremia), abdominal abscesses, and peritonitis. Extended-spectrum beta-lactamase (ESBL)-producing E. coli strains, which are resistant to many common antibiotics, have been associated with contaminated endoscope outbreaks, making these infections especially challenging to treat.
Klebsiella pneumoniae is a type of Enterobacteriaceae that has been strongly associated with contaminated Olympus duodenoscopes. Carbapenem-resistant Klebsiella pneumoniae (CRKP) is a form of CRE that has caused some of the most devastating hospital outbreaks linked to contaminated endoscopes.
Klebsiella infections from contaminated scopes can cause pneumonia, bloodstream infections, liver abscesses, meningitis, and surgical site infections. Carbapenem-resistant strains are extremely dangerous because few antibiotics can treat them, and mortality rates are high. Several of the most widely reported contaminated duodenoscope outbreaks in the United States involved Klebsiella pneumoniae.
Klebsiella can produce enzymes called carbapenemases that break down carbapenem antibiotics, rendering the most powerful available treatments useless.
The organisms listed above share a critical characteristic: they are resistant to the antibiotics doctors typically rely on to treat infections. When a patient contracts one of these pathogens from a contaminated endoscope, physicians face a devastating dilemma — the standard tools in their arsenal simply do not work.
Antibiotic resistance means longer hospital stays, more aggressive and toxic treatment regimens, higher risk of treatment failure, greater likelihood of secondary complications, and significantly higher mortality rates. For patients who went into the hospital for a routine diagnostic procedure, the idea that they could contract an untreatable infection is unconscionable.
The contamination problem is not limited to these organisms. Olympus endoscopes have also been linked to the transmission of other dangerous pathogens, including Staphylococcus aureus, Enterococcus, HIV, and tuberculosis. Any patient who developed an unexplained infection after an endoscopic procedure should seek medical evaluation and consider contacting an attorney.
If you had any endoscopic procedure and developed unexplained infection symptoms afterward, it is critical that you take both medical and legal steps to protect yourself and your rights.
If you experience fever, chills, severe abdominal pain, or any other infection symptoms after an endoscopic procedure, go to the emergency room immediately. Do not wait to see if symptoms improve on their own.
Many doctors do not immediately connect a new infection to a previous endoscopic procedure. Explicitly tell your physician that you recently had a scope procedure so they can consider contaminated equipment as a potential source of the infection.
Ask your doctor to obtain cultures to identify the specific organism causing your infection. Knowing whether you have CRE, Pseudomonas, E. coli, Klebsiella, or another pathogen is essential for both your medical treatment and any future legal claim. Culture results can directly link your infection to a contaminated scope.
Keep copies of all medical records related to both the original endoscopic procedure and the subsequent infection, including discharge summaries, lab results, culture reports, imaging studies, and billing records. These documents are critical evidence in a contaminated scope case.

Get a Free Case ReviewIf you developed an infection after an endoscopic procedure, you need to know something important: you did nothing wrong. You went to a doctor. You trusted a medical professional. You consented to a procedure that was supposed to help you. And you had every right to expect that the medical instruments used on your body were clean, safe, and free from contamination.
The failure was not yours. It was the failure of Olympus, a corporation that knew about the design defects in its endoscopes and continued to sell them to hospitals across the country. Internal documents and regulatory actions have revealed that Olympus was aware its scopes could not be adequately cleaned between patients. Despite this knowledge, Olympus continued manufacturing and marketing these devices, prioritizing profits over the safety of millions of patients.
The patients who contracted infections from contaminated scopes — and the families who lost loved ones — deserve answers. They deserve to know why a company continued selling defective products. They deserve accountability. And they deserve to be made whole for the suffering they have endured.
The Alvarez Law Firm exists to fight for exactly that kind of accountability. Our team — led by Board Certified civil trial lawyers and supported by the dual medical-legal expertise of Herb Borroto, M.D., J.D. — has the knowledge, the resources, and the resolve to take on Olympus and the healthcare facilities that failed to protect their patients.
