OLYMPUS AMERICA INC.3500 Corporate ParkwayP.O. Box 610November 12, 2012Re: Revised GI Endoscope Reprocessing ManualDear Health Care Professional:Olympus is pleased to announce validated improvements in endoscope reprocessing and the availability of a revised reprocessing manual for the following GI endoscopes:• GIF-N180• GIF-Q180• GIF-H180• GIF-XP180N• GIF-H180J • GIF-2TH180 • CF-Q180AL/I • CF-H180AL/I • CF-H180DL/I • PCF-Q180AL/I • PCF-H180AL/I • TJV-Q180V In an effort to improve reprocessing efficiency, Olympus has validated the use of water to perform endoscope precleaning at the patient’s bedside. This eliminates the need to prepare and hold detergent in the procedure room. Other improvements in the reprocessing procedure include reductions in the quantity of fluids required to flush the auxiliary water channel during bedside precleaning. In addition, the Olympus Flushing Pump,commonly known as the OFP, has been validated for automated flushing of the auxiliary water channel as an alternative to a manual syringe flushing.These new procedures, plus improvements in illustrations and additional informational material, are contained in the revised GI endoscope reprocessing manual now available from Olympus. The following is a brief description of the revisions that you will find in the revised reprocessing manual.• The precleaning procedure was revised to eliminate the use of detergent in the procedure room and toprovide the option for automated flushing of the auxiliary water channel using the OFP, Olympus Flushing Pump. The revised instructions specify the use of water to perform precleaning. Please note that thevalidation of the change to precleaning with water for the auxiliary water channel was performed with the Olympus MAJ-855 only.• Reprocessing accessories are no longer required to be detached after detergent cleaning and after rinsingprior to high-level disinfection.• Work flow charts were added to the manual to identify:o Equipment used only for patient procedures, o Equipment used only for reprocessing,o Equipment that has a role in both patient procedures and reprocessing, o Where to find instructions for reprocessing the equipment.• New illustrations were added to further clarify reprocessing instructions, and additional detail was added toexisting diagrams.• Additional instructions were added regarding:o The reprocessing of accessories.o The storage of sterilized endoscopes and accessories.• Finally, additional warnings and cautions were added to identify potential pitfalls in reprocessing practicesand policies.One caution/warning statement in the revised manual that we would like to call to your attention addresses the issue of equipment repair provided by a non-Olympus repair facility or Independent Service Organization (ISO). Olympus does not support or authorize ISOs to repair Olympus equipment, nor does Olympus provide training or parts to ISOs to enable them to repair Olympus equipment to Olympus’ standards. As a result, Olympus has no knowledge of the specifications of materials used by ISOs to repair Olympus equipment, nor the quality of such repairs. Olympus conducts a rigorous testing program to validate both compatibility of our instruments with specific reprocessing methods and agents, as well as the efficacy of such methods for reprocessing the device. Without knowledge of the materials used or the final quality of repair being provided by ISOs, Olympus is unable to validate the compatibility or reprocessing efficacy of the Olympus instructions provided in the product-specific reprocessing manual. As a result, the instructions provided in the product-specific instruction manual are invalid for Olympus equipment that has been repaired by an ISO. If your Olympus equipment was or is being repaired by a non-Olympus facility, please contact the repair facility to obtain instructions on device compatibility and reprocessing to ensure that your facility is following safe and validated reprocessing instructions.Although the new reprocessing instructions describe bedside precleaning with water, the former precleaning procedure using detergent remains a validated process and facilities may continue this practice if they so choose. In addition, the revised instructions are applicable to reprocessing the older model endoscopes that are listed in the table below. If you have questions regarding how to apply these new instructions to the older model Olympus endoscopes that you own, please contact Olympus.†Use channel cleaning brush specified in product-specific Reprocessing Manual.OLYMPUS AMERICA INC.3500 Corporate ParkwayP.O. Box 610OLYMPUS AMERICA INC.3500 Corporate ParkwayP.O. Box 610An electronic version of the newly revised manual is available on the Olympus Connect customer portal(). Hard copies may be obtained by contacting Olympus Customer Service. If you have any questions regarding the revised reprocessing manual, please contact your local Olympus sales representative or the Olympus Technical Assistance Center.

November 3, 2014RE: Guidelines for Returning Olympus Endoscopes and Electronic Equipment for Repair in the United StatesDear 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 EquipmentPrior 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 Endoscopes1. For a leak detected in the covering of the insertion tube, bending section, or universalcord, 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 drythe 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 mayresult in damage to the endoscope. For leaks detected in other locations (e.g., internalchannel), 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 afterleak testing and cleaning. It is further recommended that customers develop apath/segregation technique for endoscopes requiring repair to minimize the possibility of reuse prior to being returned to Olympus for repair.2. Fill a basin with detergent solution at the temperature and concentration recommendedby 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 thelight source and turn the maintenance unit or the light source ON. Set the light source’sairflow 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 reprocessingmanual. Minimize unnecessary flexion of the insertion tube and universal cord duringcleaning.Mandatory High-Level Disinfection or Sterilization for Leaking Endoscopes1.Sterilization:Following manual cleaning, the preferred method of rendering a leaking endoscope safe to handle is ethylene oxide sterilization. Ethylene oxide sterilization should be performedaccording 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 STERRADsterilization 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 recommendedby 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 thelight source and turn the maintenance unit or the light source ON. Set the light source’sairflow regulator switch to “HIGH” or “3.”c.Connect the leakage tester’s connector cap to the venting connector of the water-resistantcap (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 reprocessingmanual. Minimize unnecessary flexion of the insertion tube and universal cord duringreprocessing.3. Automated High-Level DisinfectionAutomated Endoscope Reprocessors (AERs) circulate high-pressure fluid through the internal channels of the endoscope, which may result in fluid invasion and further damage to aleaking 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 leakingendoscopes 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).
