Efficacy of flexible endoscope drying using novel endoscope test articles that allow direct visualization of the internal channel systems

•Novel endoscope test articles were used to evaluate drying efficacy.•Alcohol flush and hanging in a cabinet was not effective for channels.•Preoperative inspection of endoscopic channels does remove all residual liquid.•Ten minutes compressed air is always sufficient dry channels.•Factors impacting channel specific alcohol increased the time dry.•Ten channels. BackgroundThorough flexible has been identified as an essential reprocessing step. Yet, instructions are on how endoscopes. There lack data supporting efficacy current practices, due limitations determining dryness.MethodsNovel effectiveness ambient storage cabinet. Prepared hung 5 days visually inspected liquid. The procedure preoperative systems performed determine procedure's removing Then, testing assess impact pressure, liquid type route application using air.ResultsAlcohol followed by channels, completely removed after performing steps factors dependent. For some dry.ConclusionsEndoscope complex; borescope evaluation ensure device. Thorough dryness. Novel air. Alcohol dry. Endoscope
