What is the best sterilization modality recommended for a new rigid endoscope system?

The recommended sterilization modality for a new rigid endoscope system is low-temperature plasma sterilization. This method is particularly suitable for heat-sensitive medical instruments such as endoscopes, which are often made of materials that can't withstand high temperatures.

Low-temperature plasma sterilization uses a gas, typically hydrogen peroxide, which is converted into plasma to eliminate microorganisms effectively. This method offers several advantages, including rapid sterilization cycles and compatibility with a wide range of materials commonly used in endoscopes, such as plastics and delicate components.

In contrast, ethylene oxide sterilization is effective but can lead to long processing times and requires aeration to remove toxic residues, making it less ideal for certain situations compared to low-temperature plasma. High-temperature sterilization can damage sensitive instruments due to the heat, while poultry sterilization is not a recognized method for sterilizing medical instruments and is irrelevant in a medical context.
