Colonic apc refers to argon plasma coagulation performed in the colon. Argon plasma coagulation is a non-contact electrocoagulation method, high-frequency energy will be transmitted to the target tissue so as to play the role of tissue destruction and hemostasis, clinically known as argon knife. Colon apc is the implementation of argon plasma coagulation in the colon area. And because of the special physical properties of argon, the tissue will not occur carbonization, less smoke, intraoperative to maintain a clear endoscopic field of vision. At present, argon plasma coagulation has been widely used in gastrointestinal tract and respiratory endoscopy interventional therapy, mostly used for smaller benign tumors and pre-cancerous lesions of the inactivation, postoperative trauma treatment and residual foci of the inactivation, confined to intramucosal cancers or smaller early tumor treatment and gastrointestinal bleeding hemostasis, radiation proctitis, Bart’s esophagus and so on. If you are a patient who needs to implement colon apc, it is recommended to go to a regular hospital to receive consultation and treatment, so as to avoid unnecessary harm.
