title: [Use of argon plasma coagulation in digestive endoscopy: a concise review].
abstract: Argon plasma coagulation (APC) is a non-contact thermal method of hemostasis that has generated much attention in recent years. This endoscopic procedure is used primarily to control bleeding from lesions in the gastrointestinal tract, and also sometimes to debulk tumours in the case of patients for whom surgery is not recommended. APC involves the use of a jet of ionized argon gas (plasma) that is directed through a probe passed through the endoscope. The probe is placed at some distance from the lesion, and tissue damage is limited to superficial layers. The depth of coagulation is usually only a few millimetres. Theoretical advantages of APC include facility application, speedy treatment of multiple lesions in the case of angiodysplasias or wide areas (the base of resected polyps or tumor bleeding), safety due to reduced depth of penetration, and lower cost compared to laser.
