At a glance: APC is a non-contact thermal treatment used during endoscopy for selected bleeding or superficial lesions.
Argon plasma coagulation is a non-contact endoscopic treatment that uses ionised argon gas to deliver controlled thermal energy to superficial tissue.
When APC may be used
- Treatment of selected bleeding blood vessels or vascular lesions
- Radiation-related bleeding in the rectum
- Control of oozing from superficial lesions
- Selected treatment during therapeutic gastroscopy or colonoscopy
What to expect
APC is performed through an endoscope during gastroscopy, colonoscopy or flexible sigmoidoscopy. Preparation and sedation depend on the procedure being performed.
Risks
Risks depend on the treatment site and include pain, bleeding, ulceration, narrowing and, rarely, perforation. Your endoscopist will explain the expected benefits and alternatives.

Frequently asked questions
Does APC involve cutting tissue?
No. It delivers thermal energy without direct contact, although it still creates a controlled superficial treatment effect.
Will I need sedation?
Sedation depends on whether APC is performed during gastroscopy, colonoscopy or flexible sigmoidoscopy.
Can more than one treatment be needed?
Yes. Some conditions require repeat sessions depending on the response and extent of disease.
