HSPA Endoscope Reprocessing

Question 1

What is the first step that should be performed at the point of use after an endoscope procedure?

Accepted Answer

Wipe the insertion tube and flush all channels with manufacturer-recommended solution

Answer

Bedside pre-cleaning (wiping and flushing) prevents biofilm formation by removing gross soil before it dries. Manufacturer instructions typically require immediate wiping and channel flushing at the point of use. Delays allow organic material to harden, making subsequent cleaning far more difficult.

Question 2

Which type of endoscope poses the greatest reprocessing challenge due to its complex internal channel design?

Accepted Answer

Duodenoscope

Answer

Duodenoscopes (ERCP scopes) have an elevator mechanism with a narrow channel that is extremely difficult to access and clean. FDA has issued multiple safety communications regarding duodenoscope reprocessing due to outbreaks linked to inadequate cleaning of the elevator channel.

Question 3

What is the minimum recommended contact time for high-level disinfection of a flexible endoscope using 2% glutaraldehyde at 25 degrees Celsius?

Accepted Answer

20 minutes

Answer

The standard minimum contact time for 2% glutaraldehyde at 25 degrees Celsius is 20 minutes for high-level disinfection. This time is necessary to kill all vegetative bacteria, mycobacteria, fungi, and viruses. The contact time may vary with different formulations and temperatures.

Question 4

What is the purpose of a leak test performed on a flexible endoscope?

Accepted Answer

To detect damage to the outer sheath or internal channels that could allow fluid ingress

Answer

Leak testing detects perforations or damage in the endoscope's protective sheath and internal components. Fluid ingress through even a tiny breach can damage expensive internal optics and electronics. A failed leak test means the scope must be removed from service and sent for repair.

Question 5

Which organization publishes the multisociety guideline for endoscope reprocessing?

Accepted Answer

SGNA, ASGE, and other GI societies jointly

Answer

The multisociety guideline for reprocessing flexible gastrointestinal endoscopes is published jointly by organizations including SGNA (Society of Gastroenterology Nurses and Associates), ASGE (American Society for Gastrointestinal Endoscopy), and other GI specialty societies. These guidelines represent the consensus standard of care.
