immersion in glutaraldehyde or 5 minutes in peracetic acid or chlorine

dioxide is recommended.

7. Microbiological studies show that 20 minutes of exposure to 2%

glutaraldehyde destroys most organisms, including Mycobacterium

tuberculosis. The Working Party concludes therefore that 20 minute

endoscope immersion in 2% glutaraldehyde is sufficient for endoscopy

involving patients with AIDS and other immunodeficiency states or

pulmonary tuberculosis. Similarly, 20 minutes immersion time is

recommended at the start of the list and between cases for ERCP when

high level disinfection is required.

8. Cleaning and disinfection of endoscopes should be undertaken by trained

staff in a dedicated room. Thorough cleaning with detergent remains the

most important and first step in the process.

9. Automated washer/disinfectors have become an essential part of the

Endoscopy Unit. Machines must be reliable, effective, easy to use and

should prevent atmospheric pollution by the disinfectant if an irritant agent

is used. .Troughs of disinfectant should not be used unless containment or

exhaust ventilated facilities are provided.

10. A detailed cleaning and disinfection regime is preferred and this is

described.

11. Whenever possible 'single use' or autoclavable accessories should be

used. The risk of transfer of infection from inadequately decontaminated

reusable items must be weighed against the cost. Re-using accessories

labelled for single use will transfer legal liability for the safe performance of

the product from the manufacturer to the user or his/her employers and

should be avoided unless Department of Health criteria are met.

Manufacturers are encouraged to produce more reusable items which are

readily accessible for cleaning and are autoclavable.

12. Health surveillance of staff is mandatory and should include a preemployment

enquiry regarding asthma, skin and mucosal sensitivity

problems and lung function by spirometry. Occupational health records

must be retained for 30 years.

13. Those involved in endoscopic practice should be vaccinated against

hepatitis B, should wear gloves and appropriate protective clothing, and

should cover wounds and abrasions.

14. Increased funding is necessary for capital purchases of endoscopic

equipment, including more endoscopes, washer/disinfectors, exhaust

ventilation equipment and single use accessories.
