It's not fair to single out Canada. Filthy colonoscopies are everywhere:
blog.aarp.org/2013/06/12/colonoscopy-instruments-putting-people-at-hepatitis-and-infection-risk/Now a study at five hospitals nationwide finds that three out of 20 endoscopes that are inserted in the rectum to examine the colon for cancer retained bits of “biological dirt” from past patients, putting people at risk for hepatitis and infection.
“Three out of 20 is an unexpectedly high number of endoscopes failing a cleanliness criterion,” Marco Bommarito, an investigator with 3M’s infection prevention division, which conducted the study, told the Los Angeles Times. “Clearly, we’d like no endoscopes to fail a cleanliness rating.”
The study, presented at the annual conference for the Association for Professionals in Infection Control and Epidemiology, in Fort Lauderdale, Fla., found that rates for colon dirt were as high as 30 percent for reusable endoscopes used for upper gastrointestinal exams, the Times reported.
