Maintenance of gastrointestinal endoscopes

Abstract Endoscopes are used for visualization and biopsy of gastrointestinal lesions, as well as therapeutic procedures, such as foreign body retrieval. In the past, they were primarily used in large institutional settings where specialized personnel could focus on their maintenance. Today, they are becoming increasingly common in general practice. The maintenance of gastrointestinal endoscopes in the veterinary setting involves many challenges, including safe handling, reprocessing, and storage. Meeting these challenges requires well-trained personnel and strict protocols. Reprocessing, which includes cleaning and disinfection, offers the greatest challenge. The complex structure of flexible endoscopes, particularly the long, narrow channels, makes them difficult to clean. Gastrointestinal endoscopes operate in a contaminated environment, exposing them to high levels of organic matter and bacteria. High-level disinfection is necessary for infection control, but liquid germicides available for endoscope disinfection can be toxic to medical personnel and patients.
