Background And Study Aims:
Despite endoscope reprocessing, residual droplets remain in digestive endoscope working channels. Inadequate drying of digestive endoscope working channels may promote microbial reproduction, increasing risk of infection among patients. This review was designed to summarize the current status of digestive endoscope and assess effectiveness of drying methods in preventing residual droplets and microorganisms in digestive endoscope.
Methods:
PubMed, Web of Science, and EMBASE up until 2025 were searched to identify eligible articles focused on methods of digestive endoscope drying and the status of endoscope drying. The revised JBI quality assessment tool was used to determine the quality of each included article by two independent reviewers.
Results:
This review included 16 articles; six focused on residual droplets, six evaluated microbial growth, and four assessed both residual droplets and microbial growth following different digestive endoscope drying methods. Compared to the single drying method, the combination of novel automated drying techniques and guideline-recommended conventional drying methods reported lower levels of residual fluid and microbial growth in endoscope channels.
Conclusions:
Automated drying, particularly with drying cabinets, reduces residual moisture and microbial contamination on digestive endoscopes more effectively than manual drying, warranting its inclusion in standard reprocessing protocols.

Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
