Argon Plasma Coagulation Machine
Argon Plasma Coagulation (APC) Machine is used primarily to control bleeding during endoscopic or surgical procedures. It may also be used to debulk tumors (removing most of the tumour) by coagulation in the case of patients for whom surgery is not recommended. APC involves the use of a jet of ionized argon gas and high frequency current. The probe is placed at some distance from the bleeding. As no physical contact is made with the lesion, the procedure is safe.
