APC stands for Argon Plasma Coagulation and it is an endoscopic procedure which is used to control bleeding from certain tumours or cancers formed in the gastrointestinal tract. This procedure is performed when the best pulmonologist in Kolkata doesn’t feel the need of a surgery.

APC involves the utilization of a jet of ionized argon gas directed through a search initiated by the endoscope. The probe is placed at a long way from the bleeding area, and argon gas is emitted, and then ionized by a high-voltage discharge.

High-frequency current is then conducted through the jet of gas, leading to coagulation of the bleeding area. As no physical contact is formed with the lesion, the procedure is safe if the bowel has been cleaned of colonic gases. The depth of coagulation is typically only a couple of millimetres.
