What role does the endoscope manufacturer's Instructions for Use (IFU) play in scope inspection and testing?
Answer: The IFU is the authoritative document specifying all inspection criteria, test methods, acceptance criteria, and maintenance requirements for that specific scope model
The manufacturer's IFU is the legally binding, validated guidance for all aspects of scope use, inspection, and reprocessing.
Which tool is used to inspect the biopsy channel interior of a flexible endoscope for retained soil?
Answer: Channel inspection scope (mini-endoscope) or borescope
A borescope or channel inspection scope is a miniature optical device inserted into channels to directly visualize the interior for soil, damage, or blockages.
What is the significance of 'scope retirement criteria' in an endoscopy quality program?
Answer: Defined retirement criteria establish objective thresholds based on inspection findings, repair history, age, and manufacturer guidance that determine when a scope should be permanently removed from service
Objective retirement criteria prevent continued use of scopes that cannot be reliably reprocessed or safely used, removing subjective decision-making.
During a leak test, a small but consistent stream of bubbles is noted from the bending section. What is the correct response?
Answer: Deflate the scope, remove from liquid immediately, dry, tag as out of service, and send for repair
Any leak test failure, including small leaks, requires immediate removal from liquid, drying, and removal from service pending repair.
Why is it important to test ALL channels for patency, not just the suction/biopsy channel?
Answer: Each channel can independently become blocked and all channels must be cleaned during reprocessing; any blocked channel compromises the reprocessing of the entire scope
All channels are potential routes for pathogen transmission and must be accessible for cleaning; a blocked channel in any location makes that scope unsafe for patient use.
What type of light source is used in a dedicated endoscope inspection step to detect surface soil more effectively?
Answer: Bright, directed white light with magnification, sometimes supplemented by UV (black light) to highlight protein residues
Bright directed light with magnification — and optionally UV light which causes protein residues to fluoresce — improves detection of residual soil on endoscope surfaces.
