Ch.4

Argon plasma coagulation (APC)
Endoscope model: all models except BF-XP190
WARNING
• The argon gas itself is neither combustible nor a promoter of combustible
substances, but the argon plasma is very hot and could ignite combustible
substances. Flammable substances burn easily when argon is irradiated in the
presence of combustible gas such as high-concentration or pure oxygen. Be sure
to observe the following cautions.

Before and during APC, do not feed oxygen or other combustible gases and
liquids into the tracheobronchial system.

If it is required to activate APC for a few seconds, change between APC and
oxygen feeding.

Keep the distal end of the APC probe in the endoscopic image before and
during activation. Never activate APC
in a position you cannot observe.
• Do not perform APC without gloves. Operator injury can result.
• Always confirm that the tissue is an appropriate distance away from the distal end
of the endoscope. If APC is performed with the distal end of the endoscope in
contact with the tissue, patient injury may occur.
• Make sure that the distal end of the APC probe always lies more than 10 mm from
the endoscope’s distal end (see Figure 4.9). The protrusion by 10 mm or more can
be identified when the first black ring on the APC probe’s distal end is visible in the
endoscopic image. Otherwise, the treated region cannot be irradiated correctly and
the endoscope may be damaged. Using a damaged endoscope may cause patient
injury.

• Make sure that the patient plate is properly attached to patient’s skin. Improper
connection between the patient plate and patient’s skin surface may cause burns.
For further details on patient plates, refer to the patient plate’s instruction manual.
