(a) PAA-based disinfectant with addition sterile compressed air (SCA) (b) PAA-based disinfectant without additional sterile compressed air
(a) Using SCA for 2 h at 50°C. The two interventions were stored in drying cabinets for 1, 3, 5, and 7 days
Grandval
(2013)
(a) AEWD then storage cabinets for heat-sensitive endoscopes (SCHE) (b) AEWD then in a clean, dry, dedicated cupboard without morning disinfection (c) AEWD then in a clean, dry, dedicated cupboard with morning disinfection
Endoscopes of the three interventions were stored for 72 h then sampled
Saliou
(2015)
(a) AEWD then in a clean, dry, dedicated cupboard (b) AEWD then in an AS300 Hysis SCHE
(a) High-level disinfection after 12 h of storage as recommended in France (b) All channels of the endoscopes were purged with medical air for 1 hour
Hassaine-Lahfa
(2017)
(a) Without drying the material after sterilization (b) Drying the endoscope’s channels with compressed air after sterilization
Endoscopes of the two interventions were immersed in Hexanios for 20 minutes and Steranios 2% for 15 minutes

(2017)
(a) Without drying (b) Dried with compressed air (c) With 75% alcohol then dried with compressed air
(a) Dried with compressed air for 30 s (b) With 75% alcohol for 3 min then dried with compressed air for 30 s
Barakat
(2019)
(a) AER plus manual forced air drying (b) AER plus automated drying for 5 min (c) AER plus automated drying for 10 min
(a) Manual drying of the endoscope working channel for 10 minutes with forced high-efficiency particulate filtered air (HEPA) (b) and (c) Endoscopes were attached to the Dri-Scope Aid device for either 5 minutes or 10 minutes
