Reprocessing of flexible endoscopes

Proper reprocessing of endoscopes prevents the risk of transmission of infection between patients. Meticulous mechanical cleaning is the most important step as it removes the majority of the contaminating bacteria. It should be performed before manual or automatic disinfection. High-level disinfection involves total immersion of the endoscope in a liquid chemical germicide (LCG) at a preset temperature and concentration for a pre-determined period of time. Subsequent rinsing and drying are essential steps to remove the chemical solution and prevent bacterial colonization during storage. Endoscopy units that are used for more than 50 procedures per week may benefit from cleaning in an automatic endoscope reprocessor (AER). This allows automated exposure of the endoscope to the LCG with subsequent flushing and drying of the channels, and minimizes staff exposure to the LCG. Reprocessing should be performed by trained and accredited personnel according to written guidelines or standards of practice as defined by professional societies. Regular monitoring of the reprocessing process is important for quality control and in ensuring patients' safety.
