    Abstract Abstract Outbreaks of infection transmission due to contaminated flexible endoscopes have focused the attention of health care personnel, senior management, device manufacturers, and regulators on the need to improve the approach used to offer this valuable service. This chapter presents the principles of flexible endoscope reprocessing along with a pragmatic approach to the judicious selection and proper reprocessing of endoscopic equipment, as well as guidance for prevention and management of infection transmission inclusive of newer sterilization (e.g., hydrogen peroxide vapor) and disinfection (e.g., improved hydrogen peroxide) technologies. It also provides an outline of the Quality Systems approach that is applicable to flexible endoscope reprocessing and the need for ongoing staff competency and audits of endoscope cleaning, disinfection, and storage practices. Furthermore, the most current regulatory, expert organization, and manufacturer's recommendations are reviewed.

    Abstract Background and study aims: We have previously pointed out a defect of automatic endoscopic reprocessors, i. e. the contamination of the connecting part between the endoscope and the reprocessor. We evaluated a newly designed connector (MH-861; Olympus, Tokyo, Japan) with a self-cleaning and disinfection mechanism, which enabled cleaning and disinfection of both the connector itself and its interface with the suction and air/water valves during a reprocessing cycle, which was not previously possible.
    Methods: Ten upper gastrointestinal endscopes were examined in the study. Swabs were taken from the suction and air/water valves for microbiological culture before and after reprocessing by the washer-disinfector. The numbers of contaminated endoscopes before and after reprocessing with the new connector were compared.
    Results: Before the procedure there were five contaminated endoscopes and none after the procedure. When the new connector was used, the difference in cleaning and disinfection of the connecting parts was significant (P = 0.0325).
    Conclusions: We conclude that the newly developed connector permits effective cleaning and disinfection by automatic reprocessors.

    Abstract Bacterial contaimination of endoscopes can be clinically significant. While current data suggest that flexible sigmoidoscopy may entail fewer risks than upper endoscopy, these data are too incomplete to draw this conclusion. Careful cleaning and disinfection after each procedure are recommended. Gas sterilization of the endoscope and gas or heat sterilization of accessory equipment may be necessary in certain clinical situations. It must be remembered that hundreds of thousands of endoscopic procedures were performed in the 1970s using cleaning only without substantial health risk. The processes do not have to be complicated or difficult. Staff must be well trained and must understand the potential risks of working with disinfecting agents such as alkaline glutaraldehyde. It is recommended that the clinician fully understand the cleaning and disinfection steps and be able to perform them. It is important that office procedures be based on efficacy, not convenience. The procedures developed to date are not ideal and the ideal disinfectant has yet to be found. Cleaning and disinfecting machines have been developed, but they are expensive and their efficacy and safety are no better than hand-performed methods. An alternative approach to reducing transmission of infections by endoscopes may be to seek less adherent plastic substances for the endoscope sheath. The introduction of immersible endoscopes has helped with cleaning, but their use may also give rise to a false sense of security. Diligent attention to cleaning and disinfection is still necessary.(ABSTRACT TRUNCATED AT 250 WORDS)

    Abstract As part of the activities toward standardizing endoscopy procedures, the Japan Gastroenterological Endoscopy Society has prepared guidelines for cleansing and disinfection of gastrointestinal endoscopes. The environment of gastrointestinal endoscopy differs between Japan and advanced Western countries. In advanced Western countries, gastrointestinal endoscopy is performed almost exclusively at specialized facilities, where strict provisions are observed for cleansing and disinfecting endoscopes. In Japan, however, gastrointestinal endoscopy is performed even in small clinics, and the annual number of gastrointestinal endoscopy cases is enormous. In addition, the method for cleansing and disinfecting endoscopes differs among hospitals. Although there is a distinct lack of evidence for how gastrointestinal endoscopes are cleaned and disinfected, it is necessary to standardize the method for doing so to advance the field of endoscopic medicine.
