RE: Guidelines for Returning Olympus Endoscopes and Electronic Equipment for Repair

in the United States

Dear Healthcare Practitioner:

The purpose of this letter is to provide guidance to customers on our requirements when sending

Olympus endoscopy equipment to Olympus service centers located in the United States for repair.

All equipment, including flexible endoscopes, rigid endoscopes, and electronic equipment must

be rendered safe to handle prior to being returned to Olympus for repair. To accomplish this, all

endoscopes must be cleaned AND high-level disinfected or sterilized prior to shipment to a

service center for repair. Olympus Electronic Equipment must be wiped with an

appropriate surface disinfectant, such as Sani-Cloth®

Plus Germicidal Disposable Cloths

manufactured by PDI.

In addition, Olympus requires that the cleaning AND high-level disinfection or sterilization

process be verified prior to initiation of repair. To expedite repair of your equipment, please

contact Olympus at 800-848-9024 to generate a service RMA. Please complete the Reprocessing

Verification section on the equipment service request form provided. You may also generate an

RMA and complete the Reprocessing Verification on-line at

/serviceportal.

Please include the equipment service request form or portal confirmation with your equipment. If

Olympus equipment is received without a Reprocessing Verification, Olympus will contact the

customer to verify proper reprocessing prior to initiating repair. Endoscopes that have not been

cleaned AND high-level disinfected or sterilized will be returned to the customer without being

repaired.

Mandatory Surface Disinfection of Electronic Equipment

Prior to returning Olympus electronic equipment for repair, wipe all surfaces of the electronic

equipment (e.g., the video system center or light source) with a disinfectant wipe, such as Sani-Cloth® Plus Germicidal Disposable Cloths manufactured by PDI. Follow the product’s

instructions for use regarding how to wipe and the required contact time for the product to be

effective. For example, Sani-Cloth® Plus Germicidal Disposable Cloths require a 5-minute

contact time.

Mandatory Cleaning and Disinfection or Sterilization of Rigid Endoscopes:

Prior to sending rigid endoscopes to Olympus for repair, reprocess them according to the product-specific instruction manual and/or Endoscopy System Guide (if applicable), which includes the

steps of cleaning, high-level disinfection and/or sterilization.

Mandatory Cleaning and Disinfection or Sterilization of Flexible Endoscopes:

For flexible endoscopes, refer to the reprocessing manual that accompanies each endoscope for

instructions on proper manual cleaning, high level disinfection and/or sterilization, which is

required prior to returning the equipment to Olympus for repair.

The following information provides guidance on how to reprocess damaged flexible endoscopes

to render them safe to handle. Damaged endoscopes that are still watertight should be reprocessed

according to instructions provided in the Olympus reprocessing manual. However, if the

endoscope has developed a leak, routine reprocessing may lead to further damage. Therefore,

Olympus has developed special guidelines for flexible endoscopes that have failed leakage

testing.

The key to preventing further damage to a leaking endoscope is to provide positive pressure to the

endoscope during all phases of the reprocessing cycle by connecting the endoscope to the

maintenance unit (Olympus model MU-1) or light source. This will ensure that the endoscope is

pressurized throughout the entire reprocessing cycle and will help to prevent fluid from entering

the endoscope.

A leak in the endoscope will be indicated by a continuous series of bubbles emerging from a

location on the endoscope. Before removing the endoscope from the water, identify and make

note of the location of the leak. With the maintenance unit or light source still turned on and the

leakage tester still connected, remove the endoscope from the water. If the maintenance unit or

light source is turned off while the endoscope is immersed, water may invade the internal spaces

and further damage the endoscope.

Mandatory Manual Cleaning for Leaking Endoscopes

1. For a leak detected in the covering of the insertion tube, bending section, or universal

cord, turn the maintenance unit OFF. Detach the leakage tester from the maintenance unit

or the light source. Wait 30 seconds or until the covering of the bending section contracts

to its pre-expansion size. Detach the leakage tester from the endoscope. Thoroughly dry

the identified location of the leak on the outer area of the scope using alcohol and a clean

lint-free cloth. Carefully apply a piece of electrical tape over the location of the leak prior

to immersing the endoscope in detergent solution. Wrapping the tape too tightly may

result in damage to the endoscope. For leaks detected in other locations (e.g., internal

channel), proceed with the instructions provided below.

Note: Please be advised that Olympus recommends use of a colored tape, such as red,

yellow, or blue to allow for easier visual identification of a scope in need of repair after

leak testing and cleaning. It is further recommended that customers develop a

path/segregation technique for endoscopes requiring repair to minimize the possibility of

reuse prior to being returned to Olympus for repair.

Please Note:

Colored Tape

2. Fill a basin with detergent solution at the temperature and concentration recommended

by the detergent manufacturer. Use a basin that is at least 40 cm by 40 cm (16” by 16”) in

size and deep enough to allow the endoscope to be completely immersed.

3. Insert the leakage tester connector into the output socket of the maintenance unit or the

light source and turn the maintenance unit or the light source ON. Set the light source’s

airflow regulator switch to “HIGH” or “3.”

4. Connect the leakage tester’s connector cap to the venting connector of the water-resistant cap. For 190-series endoscopes, the leakage test connects directly to the venting

connector.

5. Fully immerse the endoscope in the detergent solution.

6. Perform manual cleaning according to the instructions provided in the reprocessing

manual. Minimize unnecessary flexion of the insertion tube and universal cord during

cleaning.

Mandatory High-Level Disinfection or Sterilization for Leaking Endoscopes

1. Sterilization:

Following manual cleaning, the preferred method of rendering a leaking endoscope safe to

handle is ethylene oxide sterilization. Ethylene oxide sterilization should be performed

according to the instructions provided in the endoscope’s reprocessing manual. If electrical

tape was applied to a leak detected in the endoscope’s external surface, remove the tape and

wipe with 70% ethyl or isopropyl alcohol prior to ethylene oxide sterilization.

If ethylene oxide sterilization is not possible, perform high-level disinfection or STERRAD

sterilization according to the instructions provided below.

Sterilization in a STERRAD sterilization system is also an acceptable alternative practice

provided the endoscope is listed as materially compatible with the STERRAD sterilization

system. Those endoscope models which are compatible with STERRAD sterilization may be

sterilized using the normally recommended STERRAD model, cycle and conditions (e.g.,

check booster requirements) as long as the following requirements are met: 1) The endoscope

has been properly cleaned and dried, and 2) Fluid has not invaded the endoscope. Retained

fluid will cause the STERRAD cycle to abort and may contribute to additional repairs.

2. Manual High-Level Disinfection:

a. Fill a basin with disinfectant solution at the temperature and concentration recommended

by the disinfectant manufacturer. Use a basin that is at least 40 cm by 40 cm (16” by 16”)

in size and deep enough to allow the endoscope to be completely immersed.

b. Insert the leakage tester connector into the output socket of the maintenance unit or the

light source and turn the maintenance unit or the light source ON. Set the light source’s

airflow regulator switch to “HIGH” or “3.”

c. Connect the leakage tester’s connector cap to the venting connector of the water-resistant

cap (140/160/180-series) or endoscope directly (190-series).

d. Immerse the endoscope in the disinfectant solution.

e. Perform the high-level disinfection procedure described in the endoscope’s reprocessing

manual. Minimize unnecessary flexion of the insertion tube and universal cord during

reprocessing.

3. Automated High-Level Disinfection

Automated Endoscope Reprocessors (AERs) circulate high-pressure fluid through the internal

channels of the endoscope, which may result in fluid invasion and further damage to a

leaking endoscope. As a result, Olympus recommends performing the manual high-level

disinfection procedure on leaking endoscopes.

However, some AERs are designed to maintain positive pressure to the internal cavities of the

endoscope in order to prevent fluid invasion during the reprocessing cycle. Check with your

AER manufacturer to determine whether your AER is intended to reprocess leaking

endoscopes and whether positive pressure can be maintained during the disinfection cycle

without aborting the cycle.

If you have any additional questions, please contact your local Olympus sales representative or

the Olympus Technical Assistance Center at 1-800-848-9024 (United States). Thank you.
