Hemorrhoids can be treated with laser surgery. Laser surgery for hemorrhoids is suitable for stage 2 and 3 internal hemorrhoids, and the main working principle is to use the high temperature generated by the laser to charcoal and cut the hemorrhoidal tissue. The main advantages of it are less damage during surgery, less bleeding, and faster recovery after surgery. The disadvantages are that it is easy to recur after the procedure and the indications are relatively narrow. Laser surgery is not clinically recommended for external hemorrhoids, and it is also less effective for stage IV internal hemorrhoids. Clinically, the treatment varies for different types of hemorrhoids or for hemorrhoids of varying severity, so it is recommended that patients visit a hospital to clarify the type and severity of their hemorrhoids before deciding on the next step in treatment.
