  1. Deficiencies of automatic endoscopic reprocessors : a method to achieve high-grade disinfection of endoscopes.

    Article - En anglais

    Background 

    We show that disinfection using the automatic endoscopic reprocessor is not complete and propose a method for high-grade disinfection of endoscopes.

    Methods 

    We used an automatic endoscopic reprocessor, Pyser System 83, and 2% glutaraldehyde.

    After each endoscopic procedure, the endoscopes were divided into three groups.

    Endoscopes in group A were washed only by the reprocessor.

    Group B endoscopes were washed by the reprocessor after the connectors were soaked in glutaraldehyde for 5 minutes.

    The channels, valves, connecting sections of group C endoscopes, and the connectors of the machine were sprayed with glutaraldehyde before machine-washing.

    Swabs were taken from all 13 parts of each endoscope and machine for microbiologic culture.

    Results 

    Six endoscopes were positive, cumulatively, for bacterial contamination in group A. Among group B endoscopes, one remained contaminated.

    No endoscope was positive in group C. The difference between group A and C was statistically significant (p<. 05).

    Conclusions 

    Machine washing by automatic endoscopic reprocessors may not achieve complete disinfection.

    Additional procedures are necessary.

    High-grade disinfection of the connectors is critical.

    Disinfection of the interface between the connectors is important.
