What are the surgical treatment methods for hemorrhoids?

One is traditional injection therapy, such as sclerosing agent injection therapy: there are two kinds of injections commonly used in clinic: sclerosing atrophy agent and necrotic exfoliating agent for dry hemorrhoids. Sclerosing agent is suitable for all stages of internal hemorrhoids and is commonly used in clinic at present. However, after the aseptic inflammatory reaction caused by drugs disappears, the contraction and extrusion of fibrosis are gradually relieved, and hemorrhoids are easy to recur. If the injection site is too shallow, it will easily lead to mucosal ulceration and mucosal abscess, and if it is too deep, it will easily lead to tissue sclerosis. If the dose is too large, it will cause necrosis and massive bleeding. If the liquid medicine seeps out of dental floss, it will cause severe pain, edema or thrombosis in anus. Excessive dosage of necrotizing agent can often cause postoperative necrotizing bleeding or infected necrotic surface ulcer, and it is easy to recur.

The second is the treatment of various therapeutic instruments, such as liquid nitrogen freezing, laser, microwave, electronics (including low frequency, radio frequency, capacitance field, iontophoresis and electrodynamic oscillation), HCPT and so on.
