WARNING! When performing electrosurgery on the gastrointestinal tract,
no flammable or potentially explosive endogenic gases must be present.
Particular care is required during the resection or coagulation of tumors
obstructing the colon using an HF loop or argon plasma coagulation.
Flammable gases must be suspected behind every stenosis in the colon.
Be certain to flush out at-risk sections of the intestine with CO

or argon
before activating the electrosurgical unit or argon plasma coagulator.
• The distal end of the APC probe should be not less than 3 mm and no
more than 5 mm from tissue to ensure safe ignition and application of the
argon plasma.
The recommended dosages as noted above apply for ERBE electrosurgical units
ICC 200, 300, 350. Of course the physician takes the final responsibility in each
case.
