Disinfection procedures of fiberscopes in endoscopy departments.

Disinfection of fibre endoscopes was examined in 5 endoscopy departments during endoscopy sessions. On the endoscopes, especially in the instrument channels, Pseudomonas aeruginosa and Proteus species could be regularly found, in some cases also Enterobacter cloacae and Candida albicans. With the results of disinfection experiments, proposals are made to reduce the infection risk due to insufficiently disinfected instruments in endoscopy departments.
