The key issues that determine the decision between reusable versus disposab
le accessories are cost and functionality. In most health-care systems the
availability and dissemination of endoscopic services relates directly to t
he resources (i.e. budget) of that system. Given the limitations of health-
care budgets, access to endoscopic services will depend upon the cost effic
iency of endoscopic practice. The onus on endoscopists and health-care prov
iders, therefore, is to meticulously evaluate the necessary steps for safe
reutilization of accessories. This paper addresses the principles of reuse,
quality assurance and particularly disinfection practices. Any change to a
more costly disposable accessory policy must bear the responsibility of de
nied access to endoscopic services in a system with finite resources. (C) 2
