10 to 30% of patient-ready endoscopes are contaminated with microorganisms.
- If contaminated scopes are used, investigators noted high rates of transmission.
- More outbreaks are linked to contaminated endoscopes than to any other medical device.
- Endoscopes not sterilized, hence reprocessing has narrow margin of safety. Any slight deviation can lead to survival of microorganisms.
- Endoscopes are significant vectors for nosocomial transmission of microorganisms as a result of scope contamination from the patient or from the inanimate environment (e.g. automated endoscope reprocessing devices).

BIOFILMS & ENDOSCOPY
TEST YOUR ENDOSCOPE IF IT'S NOT CLEAN, IT SHOULDN'T BE DISINFECTED
- Growth of bioﬁlms inside endoscope channels can result in failure of endoscope reprocessing and is an important factor in the pathogenesis of endoscopy-related infections.
- Microbial surveillance to monitor endoscopes after reprocessing has been recommended by a majority of organizations (ASGE, ESGE, ESGENA, GESA).
- Countries with systematic endoscope monitoring confirm high contamination rates.
Inorganic and organic materials interfere with the effectiveness/ antimicrobial activity of disinfectants and sterilization.
It is impossible to disinfect an inadequately cleaned instrument.
“Any disinfection process is doomed to fail if cleaning is inadequate.”
