Endoscopy

On average, 19.98 % of reprocessed gastrointestinal endoscopes may be contaminated when used in patients and varies between different geographies (PubMed Central june 2022)

Biofilms & endoscopy

  • ” The utility of lighted magnification and borescopes for visual inspection of flexible endoscopes”
    Visible damage and residue or debris were observed in 100% of 25 endoscopes at both assessments … read more here 

  • 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.6

  • 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.

Why worry about endoscopes ?

10 to 30% of patient-ready endoscopes are contaminated with microorganisms.1

  • If contaminated scopes are used, investigators noted high rates of transmission.²

    More outbreaks are linked to contaminated endoscopes than to any other medical device.³

  • Endoscopes not sterilized, hence reprocessing has narrow margin of safety. Any slight deviation can lead to survival of microorganisms.⁴

  • 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).⁵

Infection & endoscopy

  • Infection rates “far higher” than expected in US endoscopy centers.
  • An update on gastrointestinal endoscopy-associated infections and their contributing factors.
  • IF IT’S NOT CLEAN, IT SHOULDN’T BE DISINFECTED
  • Inorganic and organic materials interfere with the effectiveness/ antimicrobial activity of disinfectants and sterilization.²
  • It is impossible to disinfect an inadequately cleaned instrument.²
  • “Any disinfection process is doomed to fail if cleaning is inadequate.”⁷
