Precautions
•
Failure to properly clean and high-level disinfect or sterilize
endoscopic equipment after each examination can
compromise patient safety. To minimize the risk of
transmitting diseases from one patient to another, after each
examination the endoscope must undergo thorough manual
cleaning followed by high-level disinfection or sterilization.
•
ALL channels of the endoscope, including auxiliary water
channel where fitted, MUST be cleaned and high-level
disinfected or sterilized during EVERY reprocessing cycle,
even if the channels were not used during the previous
patient procedure. Otherwise, insufficient cleaning and
disinfection or sterilization of the endoscope may pose an
infection control risk to the patient and/or operators
performing the next procedure with the endoscope.
•
If the endoscope is not cleaned meticulously, effective
disinfection or sterilization may not be possible. Clean the
endoscope and accessories thoroughly before disinfection or
sterilization to remove microorganisms or organic material
that could reduce the efficacy of disinfection or sterilization.

•
Olympus confirms validation of the endoscope reprocessors
recommended by Olympus only. If using endoscope
reprocessor that are not recommended by Olympus, the
endoscope reprocessor manufacturers are responsible for
validation of the endoscope reprocessor with the endoscope
models listed in its intended use statement. If using an
endoscope reprocessor, confirm that it is capable of
reprocessing endoscope including all channels. If there are
channels and/or other parts which cannot be cleaned and
high-level disinfected by the endoscope reprocessor, have to
undergo manual cleaning and high-level disinfection or
sterilization as described in Chapter 3, “Cleaning,
Disinfection and Sterilization Procedures” after using the
endoscope reprocessor. Otherwise, insufficient cleaning and
disinfection or sterilization of the endoscope may pose an
infection control risk to the patient and/or operators
performing the next procedure with the endoscope. If you are
uncertain as to the ability of your endoscope reprocessor to
clean and high-level disinfect endoscope including all
channels, contact the endoscope reprocessor supplier for
specific instructions and/or connectors.
•
Patient debris and reprocessing chemicals are hazardous.
Wear personal protective equipment to guard against
dangerous chemicals and potentially infectious material.
During cleaning and disinfection or sterilization, wear
appropriate personal protective equipment, such as eye
wear, face mask, moisture-resistant clothing and
chemical-resistant gloves that fit properly and are long
enough so that your skin is not exposed. Always remove
contaminated personal protective equipment before leaving
the reprocessing area.
•
Thoroughly rinse off the disinfectant solution. Rinse the
external surfaces of the endoscope, channels and cleaning
equipment thoroughly with clean water to remove any
disinfectant solution residue.
•
The disinfection/sterilization room must be adequately
ventilated. Adequate ventilation protects against the buildup
of toxic chemical fumes.

Endo-therapy accessories which are marked by the words
“AUTOCLAVE” or “AUTOCLAVABLE”, or accessories with a
green model reference label, are compatible with
autoclaving.
2.2
Detergent solution
Use a medical-grade, low-foaming, neutral pH detergent or enzymatic detergent
and follow the manufacturer’s dilution and temperature recommendations.
Contact Olympus for the names of specific brands that have been tested for
compatibility with the endoscope. Do not reuse detergent solutions.
Excessive detergent foaming can prevent fluid from
adequately contacting internal lumens (e.g. channels).
2.3
Disinfectant solution
In the U.S., agents used to achieve high-level disinfection are defined as liquid
chemical germicides registered with the U.S. Food and Drug Administration as
“sterilant/disinfectants” which are used according to the time, temperature and
dilution recommended by the disinfectant manufacturer for achieving high-level
disinfection. These conditions usually coincide with those recommended by the
disinfectant manufacturer for 100% kill of mycobacterium tuberculosis.
In general, 2.0 – 3.5% glutaraldehyde solutions, when used according to the
manufacturer’s instructions for achieving high-level disinfection, are compatible
with Olympus endoscopes. Contact Olympus for the names of specific brands
that have been tested for compatibility with the endoscope.
If the disinfectant solution is reused, routinely check its efficacy with a test strip
recommended by the manufacturer. Do not use solutions beyond their expiration
date.
Alcohol is not a sterilant or high-level disinfectant.

2.4
Rinsing water
Once removed from disinfectant solution, the instrument must be thoroughly
rinsed with sterile water to remove any disinfectant residue. If sterile water is not
available, clean potable tap water or water which has been processed (e.g.
filtered) to improve its microbiological quality may be used.
When non-sterile water is used after disinfection, wipe the endoscope and flush
the channels with 70% ethyl or isopropyl alcohol, then air-dry all internal
channels to inhibit the growth of residual bacteria. Do not reuse rinsing water.
2.5
ETO gas sterilization
This instrument and other accessories listed as compatible with ethylene oxide
(ETO) gas sterilization in Table 2.1 can be sterilized by ETO gas and aerated
within the parameters given in Table 2.2. When performing sterilization, follow
the hospital’s protocol and the sterilization equipment manufacturer’s
instructions.

•
Before sterilization, the instrument must be thoroughly
cleaned and dried. Residual moisture inhibits sterilization.
•
The results of sterilization depend on various factors such as
how the sterilized instrument was packed or the positioning,
method of placing and loading of the instrument in the
sterilization device. Please verify the sterilization effects by
using biological or chemical indicators. Also follow the
guidelines for sterilization issued by medical administrative
authorities, public organizations or the infection management
sections at each medical facility, as well as the instruction
manual of the sterilization device.
•
All instruments must be properly aerated following ETO gas
sterilization to remove toxic ethylene oxide residuals.
•
Exceeding the recommended parameters may cause
equipment damage.
•
When reprocessing EVIS videoscope models, remove the
water-resistant cap before ETO gas sterilization (see Figures
2.1 and 2.2). When reprocessing OES fiberscope models,
install the ETO cap on the venting connector of the
endoscope’s light guide connector section before ETO gas
sterilization (see Figure 2.3). If ETO gas sterilization is
performed while the water-resistant cap is installed or the
ETO cap is not attached, air inside the endoscope will
expand and could rupture the covering of the bending
section.
•
Repeated ETO gas sterilization procedures will gradually
deteriorate the instrument. Do not perform ETO gas
sterilization to the instrument unnecessarily.

Steam sterilization (autoclaving) of accessories
The accessories listed as compatible with steam sterilization (autoclaving) in
Table 2.1 can be sterilized by steam within the parameters given in Table 2.3.
When steam sterilizing, follow the hospital’s protocol and the sterilization
equipment manufacturer’s instructions.
•
The results of sterilization depend on various factors such as
how the sterilized instrument was packed or the positioning,
method of placing and loading of the instrument in the
sterilization device. Please verify the sterilization effects by
using biological or chemical indicators. Also follow the
guidelines for sterilization issued by medical administrative
authorities, public organizations or the infection management
sections at each medical facility, as well as the instruction
manual of the sterilization device.
•
Exceeding the recommended parameters may cause
equipment damage.
•
Do not steam sterilize the endoscope. Steam sterilization
(autoclaving) will severely damage the endoscope.
•
Effective sterilization will not be possible if items are packed
tightly together in the autoclave; always pack items loosely.
•
Inspect each instrument package for openings, tears or other
damage. If an instrument package is opened or damaged,
seal the components in a new package and sterilize again.
•
Allow the packages to dry within the autoclave, using the
autoclave’s drying cycle (if available) or by opening the door
of the autoclave and allowing the packages to air-dry.
Handling a wet package can compromise its sterility.
•
