ENF-V3 OPERATION MANUAL
WARNING
• Do not rely on the NBI observation mode alone for primary detection of lesions to
make a decision regarding any potential diagnostic or therapeutic intervention.
• The shape and size of the nasal cavity and its suitability for transnasal insertion
may vary from patient to patient. No endoscope, including this one, can always be
inserted transnasally into all patients. Before proceeding, always be sure to confirm
that transnasal insertion is possible with the patient by considering both the size of
the patient’s nasal cavity as well as the size of the endoscope’s insertion section.
Otherwise, patient injury can result or the endoscope could become lodged and
difficult to withdraw.
• Transnasal insertion is accompanied by the risk of inflammation of the nasal cavity.
If this happens, the nasal passage will be constricted, making it more difficult to
withdraw the endoscope. In this case, do not use force to withdraw the endoscope
because patient injury, bleeding, and/or perforation may result.
• Transnasal insertion is accompanied by the risk of bleeding in the nasal cavity. Be
sure to be prepared to deal with any bleeding. When withdrawing the endoscope,
observe the inside of the nasal cavity to ensure that there is no bleeding. Even
when the endoscope has been withdrawn without bleeding, do not allow the patient
to blow his or her nose strongly because this could cause it to start bleeding.
• Before transnasal insertion, apply the appropriate pretreatment and lubrication to
the patient to enlarge the nasal cavity. Otherwise, patient injury can result or the
endoscope could become lodged and difficult to withdraw. When applying a
pretreatment agent through a tube, insert the tube into the same path as the path
planned for the endoscope’s insertion. Otherwise, the treatment will have no effect.
The effects of the pretreatment agent and lubricant will decrease the longer the
procedure lasts. Apply the pretreatment agent or lubricant as required during the
procedure – for example, when withdrawal seems to be difficult.
• Transnasal insertion of the endoscope should be performed carefully. If resistance
to insertion is felt, or the patient reports pain, stop the insertion immediately. Patient
injury can result or the endoscope could become lodged and difficult to withdraw.
• If it becomes impossible to withdraw the transnasally inserted endoscope, pull its
distal end out of the mouth, cut the flexible tube using wire cutters, and after
ensuring that the cut section will not injure the body cavity or nasal cavity of the
patient, withdraw the endoscope carefully. Therefore, always prepare wire cutters
in advance.
• When performing the NBI observation of an oral cavity, cut off the extraneous light
as much as possible, such as dimming the room light. Otherwise, the examination
might not be done properly.
• When using the image magnification function of the video system center, never
insert or withdraw the endoscope’s insertion section while the image is magnified.
Patient injury, bleeding, and/or perforation can result.
