Colonoscopes are among the most commonly used endoscopes in medicine. If you developed a serious infection after a colonoscopy involving an Olympus colonoscope, you may have legal options.
A colonoscope is a long, flexible endoscope designed to examine the entire colon and terminal ileum. It features a high-resolution camera, a light source, working channels for instruments, and suction/irrigation capabilities. Colonoscopy is one of the most frequently performed endoscopic procedures in the United States, with millions conducted annually for colorectal cancer screening, polyp removal, and diagnostic evaluation.
Colonoscopes have multiple internal channels that must be meticulously cleaned and disinfected between patients. The working channel, suction channel, air/water channels, and auxiliary water channel all create potential harboring sites for bacteria if reprocessing is incomplete. The length and complexity of these channels—often exceeding 160 centimeters—present significant reprocessing challenges.
Olympus is a leading manufacturer of colonoscopes used across the United States. Models such as the CF-HQ190L, CF-H190L, and PCF-H190L are widely deployed in hospitals and ambulatory surgery centers. When these devices are not adequately cleaned, patients may be exposed to harmful pathogens from previous patients.
Olympus colonoscopes and contamination concerns
While duodenoscopes have received the most attention in the Olympus litigation, colonoscopes also present contamination risks. The FDA has documented reprocessing failures across multiple endoscope types, and colonoscopes have been identified in outbreak investigations involving bacterial transmission between patients.
Olympus colonoscope lawsuits allege that the company's reprocessing instructions may not adequately address contamination risks, that certain design features make thorough cleaning difficult, and that Olympus failed to promptly communicate known risks to healthcare providers and patients.
In some cases, hospitals have discovered persistent contamination on colonoscopes despite following recommended reprocessing protocols. These findings support claims that the device design itself—not just user error—contributes to cross-contamination risk.
Injuries from contaminated colonoscopes
Patients exposed to contaminated colonoscopes during colonoscopy procedures may experience:
Bacterial infections including E. coli, Klebsiella, and Pseudomonas from cross-contamination
Bloodstream infections (bacteremia) requiring hospitalization and IV antibiotics
Sepsis from pathogens introduced through the colonoscope during the procedure
Post-polypectomy infections at tissue removal sites exposed to contaminated instruments
Perforation injuries from device malfunction or component failure
Hemorrhage requiring emergency intervention
Transmission of bloodborne pathogens in rare cases of severe reprocessing failure
Legal basis for colonoscope claims
Colonoscope injury and infection lawsuits against Olympus may include claims of defective design (internal channels that cannot be adequately cleaned), failure to warn (insufficient guidance about contamination risks), and negligent post-market surveillance (delayed response to adverse event reports involving colonoscopes).
Because colonoscopies are routine screening procedures, patients have a reasonable expectation of safety. When a device introduces preventable infection risk due to design or maintenance failures, manufacturers may be held liable for resulting injuries.
Evidence that supports a colonoscope claim
Colonoscopy procedure records identifying the Olympus colonoscope model used
Post-procedure infection diagnosis within 90 days, supported by cultures or lab work
Hospital records documenting escalation of care (ER visits, admission, ICU)
Any communications from the hospital about equipment-related infection concerns
Records from follow-up care related to your post-colonoscopy infection
