title: Bacteriological efficiency of a standardized cleansing and disinfection technique for duodenoscopes.
abstract: Adequate cleansing and disinfection of the endoscopes is desirable to prevent bacteriaemia and septicemia following gastrointestinal endoscopy, especially endoscopic retrograde cholangiopancreatography and duodenoscopic sphincterotomy. A practical method, proved in our department over a period of 12 months, is described. As the result of this standardized cleansing and disinfection technique using the aldehyde derivative Gigasept (succine dialdehyde and 2,5-dimethoxytetrahydrofuran) in a 10% concentration as chemical disinfectant, sterile cultures from the biopsy channel were obtained in 75% of tested instruments. The remaining fiberscopes exhibited only a few bacteria left, resulting in a sufficient success of disinfection according to hygienic standards.
