Why should soaking flexible scopes for a prolonged time be avoided?

• A. Formation of biofilm
• B. Reduction of cleaning effectiveness
• C. Degradation of the scope material
• D. Increased risk of cross-contamination

Answer: (A)

Soaking flexible scopes for an extended duration should indeed be avoided primarily because of the risk of biofilm formation. Biofilms are complex structures formed by microorganisms that adhere to surfaces, and in the case of flexible endoscopes, these biofilms can develop when scopes are exposed to moisture over time. If a flexible scope is soaked for too long, the microorganisms can proliferate and create a protective layer that makes them significantly more resistant to disinfection and cleaning processes. Once biofilms are established, they are particularly difficult to remove, posing an ongoing risk of contamination even after attempted cleaning. While the other choices mention relevant concerns, they do not address the specific consequences of prolonged soaking as thoroughly as biofilm formation does. For instance, while material degradation is a potential issue, it typically depends on the specific chemicals used during the soaking process rather than the soaking itself. Increased risk of cross-contamination is also a concern, but it is closely related to instances where biofilms are present. The cleaning effectiveness can indeed be affected, but it's more about how biofilms interfere with the cleaning process rather than the soaking duration itself.
