Endoscopic Thoracic Sympathectomy (ETS)
Endoscopic thoracic sympathectomy (ETS) is surgery to treat sweating that is much heavier than normal. This condition is called hyperhidrosis. Usually the surgery is used to treat sweating in the palms or face. The sympathetic nerves control sweating. The surgery cuts these nerves to the part of the body that sweats too much.
