When performing, the doctor will check the area where colon polyps appear and conduct electrocautery cutting. Each excision can remove 50-60 polyps. This procedure is quite safe so the patient can be discharged immediately after the surgery. Only cases with symptoms of difficulty in hemostasis should be followed up for longer.
