APC

Argon plasma coagulation (APC) is a medical procedure used during colonoscopy or upper endoscopy to stop bleeding from certain lesions in the gut. It uses argon gas instead of cauterization or lasers to control internal bleeding.

APC can also help shrink tumors in people who can’t have surgery. It’s a safe and effective way to treat bleeding and certain growths in the digestive tract.

For this procedure, doctors often use intravenous sedation to keep you relaxed. They insert an endoscope and pass a probe into your gastrointestinal tract. The probe shoots out ionized gas toward the bleeding spot or tumor.

When argon gas mixes with electricity, it forms a gas that stops bleeding by coagulating the lesion or tumor. It’s a way to treat bleeding or growths in the digestive tract.
