Argon Plasma Coagulation (APC) is a medical procedure used to treat gastrointestinal conditions by delivering a high-frequency electrical current to targeted tissues using ionized argon gas. This creates a plasma beam that heats and coagulates the tissue, leading to thermal ablation or coagulation. APC is commonly used during endoscopy to treat conditions such as gastrointestinal bleeding, benign and malignant lesions, and other abnormalities. It offers advantages such as minimally invasive treatment, precise targeting, effective hemostasis, and generally favorable safety profile when performed by trained professionals. However, careful patient selection and appropriate training are crucial to minimize potential complications such as perforation or stricture formation. Overall, APC is a valuable tool for managing gastrointestinal conditions, providing effective treatment with minimal invasiveness.
