The assertion that flexible endoscopes do not require a ventilation adaptor or water-resistant cap during ethylene oxide sterilization is supported by established sterilization protocols. Ethylene oxide (EtO) sterilization operates under specific conditions that allow for the effective penetration of gas throughout the endoscope, regardless of the presence of these additional attachments.

Most flexible endoscopes are designed to allow for gas flow through their lumens without the need for a ventilation adaptor or water-resistant cap. The sterilization process is capable of reaching all surfaces within the endoscope efficiently, as the gas can permeate the materials effectively without causing any harm or leaving harmful residues.

Furthermore, it is crucial to understand that the manufacturer's instructions and guidelines should always be adhered to. However, for the general practice of sterilizing flexible endoscopes with ethylene oxide, the absence of a ventilation adaptor or cap is often standard because it does not hinder the sterilization effectiveness.

This understanding is fundamental for ensuring proper sterilization practices while also minimizing unnecessary additions that may complicate the process or affect the endoscope's functionality post-sterilization.
