2023年12月11日 · Argon plasma coagulation (APC) is a medical procedure that applies ionized gas and an electrical current to your digestive tract. It’s performed during a colonoscopy or upper endoscopy to seal bleeding, reduce tumors or stop weight gain after weight loss surgery.

Argon plasma coagulation (APC) is a non-contact thermal method of hemostasis. It was introduced as an alternative to contact thermal coagulation (heater probe and bipolar cautery) …

Argon plasma coagulation (APC) is a medical endoscopic procedure used to control bleeding from certain lesions in the gastrointestinal tract. It is administered during gastrointestinal endoscopy such as esophagogastroduodenoscopy or colonoscopy .

Argon Plasma Coagulation (APC) is an application of gas discharges in argon in electrosurgery, which is increasingly used especially in endoscopy. The major application fields are haemostasis, tissue devitalization and tissue reduction.

1.1 Argon Plasma Coagulation (APC™) This phenomenon offers particular advantages for endoscopic applications as it permits the argon plasma to be applied both en face and tangentially (Fig. 2), allowing the potential for less accessible regions to be treated. Properties of Argon Gas Argon (Ar) is a colorless, odorless and tasteless noble gas ...

Argon plasma coagulation (APC) is a newer technique in flexible endoscopy with many potential applications, including tumor debulking, 7 ablation of vascular malformations, 8 and coagulation of peptic ulcer bleeding sites. 9 It also has a role in “tidying up” residual adenoma after piecemeal polypectomy, although overuse in this setting ...

What is Argon? In argon-enhanced coag, activating the handset creates an argon gas plasma between the electrode and the tissue. The presence of inert gas at the surgical site inhibits combustion with other gases (e.g., oxygen, nitrogen, etc.) and pushes residual smoke, water vapor, or fluids away from the

The argon plasma coagulator (APC) is a non-contact method of delivering high-frequency monopolar current through ionized and electrically conductive argon gas, which is called argon plasma. Initially developed for the surgical arena, this device has seen an ever-expanding role in therapeutic endoscopy.1–4 The purpose of this technical review ...

Aim: The main objective of this study was to evaluate whether argon plasma coagulation (APC) is an effective and safe modality for treating early gastric cancer untreatable by surgical resection or EMR.

1992年11月1日 · It provides radio frequency coagulation from an electrosurgical generator that is capable of delivering monopo- lar current through a flow of ionized argon gas. This steady flow of gas is responsible for con- ducting radio frequency energy to the tissue.
