How can a flexible endoscope be sterilized?

The correct method for sterilizing a flexible endoscope involves utilizing high-level disinfectants or autoclaving. High-level disinfection is crucial as it destroys most microorganisms, including bacteria, viruses, and fungi, which is essential for patient safety. Autoclaving, which uses steam under pressure, is another effective method but is typically applicable only to certain parts of endoscopes that are heat resistant and not delicate components.

Effective sterilization is vital in endoscopy due to the invasive nature of the procedures, as flexible endoscopes often come into contact with mucous membranes and, if not properly sterilized, can lead to infections.

The other options do not provide adequate sterilization. Rinsing with water is insufficient as it does not eliminate pathogens. Soaking in a saline solution does not provide any antimicrobial action needed for sterility. Exposing endoscopes to UV light can reduce certain microorganisms, but it may not achieve the degree of disinfection required for medical use and is generally not recognized as a standard method for sterilization in this context.
