Argon plasma coagulation (APC)
Argon plasma coagulation (APC) is a minimally invasive procedure that uses ionized argon gas to treat bleeding or lesions in the gastrointestinal (GI) tract. It can also help with weight regain after gastric bypass surgery.
How it works
- A high voltage spark ionizes argon gas that's sprayed from a probe tip
- The ionized gas, or plasma, seeks a ground in nearby tissue
- The plasma delivers thermal energy, coagulating tissue
When it's used To stop bleeding in the GI tract, To reduce tumors, and To stop weight regain after gastric bypass surgery.
Safety
- APC is generally safe and has minimal complications
- The intravenous injection given for sedation may cause a local reaction or bruising under the skin
Recovery
- Some patients report mild abdominal discomfort or bloating
- In certain cases, doctors might suggest avoiding hard-to-digest foods for a few days
- Routine check-ups are recommended to monitor for any complications
