The Pauldrach Endocleaner was evaluated for the disinfection of gastrointestinal fibrescopes, and found to be a convenient, relatively inexpensive machine for use in endoscopy clinics. An experimental procedure was designed, for use with the endocleaner, which allowed application of an inoculum of Pseudomonas aeruginosa to a Fujinon OX52 endoscope and its subsequent quantitation before and after disinfection procedures. Using aldehyde based disinfectants ('Cidex', 'Kohrsolin' and 'Gigasept') it… Expand
In-hospital evaluation of orthophthalaldehyde as a high level disinfectant for flexible endoscopes☆
In-hospital evaluation supports the conclusion that OPA is an effective choice as a high level disinfectant for flexible endoscopes. Expand
Endoscope decontamination: a comparison of the Wolf 35100 and DSD-91 systems.
The DSD-91 machine has certain advantages over the Wolf 35100 in terms of endoscope capacity, running costs and ease of maintenance, and both machines give similar results for endoscope disinfection. Expand
In-hospital evaluation of contamination of duodenoscopes: a quantitative assessment of the effect of drying.
Although no infections related to use of contaminated endoscopes were reported, it was apparent that Gram-negative bacilli were multiplying to unacceptably high concentrations and that this could be prevented by an additional 10 min of drying. Expand
Disinfection of gastrointestinal endoscopes
The character of gastrointestinal examinations in the future will be more and more complex and invasive; in addition the number of immune compromised patients suffering from gastrointestinal diseases and needing endoscopic intervention will increase, and the risk of endoscopic transmission of microbiological particles will be higher, and procedures have to focus on procedures to prevent these infections. Expand
How well are endoscopes cleaned and disinfected between patients?
It is concluded that in the majority of hospitals where endoscopies are performed that responded to the survey, there was considerable room for improvement in the cleaning and disinfection of endoscopes. Expand
Assessment on Experimental Bacterial Biofilms and in Clinical Practice of the Efficacy of Sampling Solutions for Microbiological Testing of Endoscopes
The efficiency and therefore the value of the monitoring of endoscope reprocessing by microbiological cultures is dependent on the sampling solutions used, and a sampling solution with a tensioactive action is more efficient than saline in detecting biofilm contamination of endoscopes. Expand
Glutaraldehyde: Current Status and Uses
Despite its toxicity for medical staff, glutaraldehyde remains an invaluable compound for high-level disinfection purposes in endoscopy units. Expand
Effect of sodium hydroxide and two proteases on the revival of aldehyde‐treated spores of Bacillus subtilis
Spores of Bacillus subtilis were subjected to a 24 h exposure (22 d̀C) to vaious commercial and non‐commercial aldehyde formulations Subsequent treatment with sodium hydroxide (15 min, 22 d̀C)enabledExpand

Recent advances in the cleaning and disinfection of fibrescopes.
Abstract Methods of decontamination of flexible fibreoptic gastroscopes are described and include chemical disinfection using either a manual method or a machine, ethylene oxide or low temperatureExpand
Comparison of automated systems for the cleaning and disinfection of flexible fibreoptic endoscopes.
Thorough cleaning and disinfection will not only reduce the likelihood of infection but will also reduce channel blockages and the general deterioration of the fibrescope. Expand
Disinfecting endoscopes: how not to transmit Mycobacterium tuberculosis by bronchoscopy.
Mycobacterium tuberculosis was cultured from the bronchial washings of two patients who underwent bronchoscopy consecutively with the same bronchoscope, later confirmed in the first patient, whereas the second patient had clinical and serologic evidence of infection with respiratory syncytial virus. Expand
Disinfection of gastrointestinal fibre endoscopes.
Gastrointestinal fibre endoscopes and ancillary equipment were found to be contaminated with bacteria and a disinfection method using glutaraldehyde was simple, quick and effective. Expand
Salmonella typhimurium. Transmission by fiberoptic upper gastrointestinal endoscopy.
A retrospective cohort study confirmed the association between S typhimurium infection and fiberoptic upper GI endoscopy and Salmonella transmission was attributed to inadequate disinfection of the endoscope and accessory equipment between procedures. Expand
Effect of pH on sporicidal and microbicidal activity of buffered mixtures of alcohol and sodium hypochlorite.
High sporicidal activity can be achieved with low concentrations of alcohol and hypochlorite with promise for the disinfection of heat-sensitive medical equipment by buffering alcohol/hypochlorites mixtures or hypoch chlorite solution alone in the pH range 7.6--8.1. Expand
Abstract In a six-month period Salmonella kedougou was isolated from 20 people who were associated with the gastroenterology department of a large district general hospital. Although a common sourceExpand
