Colonoscopy is one of the most common endoscopic procedures in America. If you developed a serious infection after colonoscopy involving an Olympus colonoscope, you may be eligible for a free case review.
Colonoscopy is a procedure that uses a long, flexible colonoscope to examine the interior of the colon (large intestine) and rectum. It is the gold standard for colorectal cancer screening and is also used for diagnostic evaluation of symptoms including rectal bleeding, changes in bowel habits, chronic diarrhea, and unexplained abdominal pain.
During colonoscopy, the physician can identify and remove polyps (polypectomy), take tissue biopsies, and treat certain conditions such as bleeding lesions. The procedure typically requires sedation and bowel preparation. Over 15 million colonoscopies are performed annually in the United States, making it one of the highest-volume endoscopic procedures.
The colonoscope's internal channels—working channel, suction channel, air/water channels—must be meticulously reprocessed between patients. When cleaning fails, bacteria from one patient can be transmitted to the next through these channels, potentially causing serious infections.
Colonoscope contamination and patient safety
The sheer volume of colonoscopy procedures amplifies the impact of contamination risks. Even a small per-procedure infection rate translates to thousands of potentially affected patients per year. Studies have documented viable bacteria on colonoscopes after standard reprocessing, raising concerns about the effectiveness of current cleaning protocols.
The colon naturally contains trillions of bacteria, meaning colonoscopes are exposed to heavy bacterial loads during every procedure. This makes thorough reprocessing critically important—and more challenging. Biofilm formation inside colonoscope channels can create persistent contamination that resists routine cleaning and disinfection.
The FDA has acknowledged reprocessing concerns across all flexible endoscope categories, including colonoscopes. Professional societies have issued updated guidelines, and some facilities have adopted enhanced reprocessing technologies to address known limitations.
Injuries from colonoscopy infections
Patients who develop infections from contaminated colonoscopes may experience:
E. coli, Klebsiella, or Pseudomonas infections from cross-contamination
Post-polypectomy infections at tissue removal sites exposed to contamination
Bacteremia requiring hospitalization and IV antibiotic therapy
Sepsis from intestinal organisms entering the bloodstream
Colonic perforation from device malfunction or structural failure
Hemorrhage requiring transfusion or emergency intervention
Peritonitis if perforation or transmural contamination occurs
Legal basis for colonoscopy infection claims
Colonoscopy infection lawsuits allege that Olympus colonoscopes have design features that prevent adequate reprocessing, that the company's cleaning instructions are insufficient to eliminate contamination, and that Olympus failed to timely communicate known risks to patients and healthcare providers.
The routine, screening nature of colonoscopy strengthens these claims: patients undergoing recommended cancer screening have every reason to expect that the procedure will not introduce life-threatening infections. When device design or manufacturer instructions contribute to contamination, product liability law provides remedies.
Evidence for colonoscopy infection claims
Colonoscopy procedure record identifying the Olympus colonoscope model
Post-procedure infection diagnosed by stool or blood cultures within 90 days
Hospitalization records for treatment of the post-colonoscopy infection
Emergency room visits or urgent care for post-procedure symptoms
Follow-up treatment and any complications from the infection
