Expired endoscopic devices remain sterile and functional: an international multicentre study challenging current shelf-life criteria.

Basic sciencehealth servicescost-effectivenessendoscopy qualityepidemiology
Clinical takeawayNo clinical action yet: this is a bench and ex vivo study evaluating sterility and functionality, not clinical safety or efficacy in humans.
What it foundExpired endoscopic devices showed 100% sterility (95% CI 98.6-100) and 99.5% functionality (95% CI 97.4-99.9) beyond labelled expiry dates.
ContextChallenges current shelf-life assumptions for endoscopic devices but does not provide evidence for routine clinical use of expired devices.
No standard claimed for this paper

Every paper is compared to the standard governing its question. This one is not: either no standard in the corpus matches it, or the comparison did not hold up on review and was withdrawn rather than published unverified. Both are logged.
