Definition Return to top
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 surgery stops or turns off the nerve signals that tell the part of the body to sweat too much.
Description Return to top
You will receive general anesthesia before surgery. This will make you unconscious and unable to feel pain.
Your surgeon will make 2 or 3 tiny incisions (cuts) under one of your arms.
After doing this procedure on one side of your body, your surgeon will do the same thing on the other side. The surgery takes about 1 hour total.
Why the Procedure is Performed Return to top

Your doctor or nurse will tell you when to arrive at the hospital.
After the Procedure Return to top
Most people stay in the hospital 1 night and go home the next day. You may have pain for about a week. Take pain medicine as your doctor told you to. You may be taking acetaminophen (Tylenol) or prescription pain medicine. Do not drive if you are taking narcotic pain medicine.
Keep your incision areas clean, dry, and covered with dressings (bandages). Wash the areas and change the dressings as your doctor told you to. Do not soak in a bathtub or hot tub, or go swimming, for about 2 weeks.
Slowly resume your regular activities as you are able to.
Your doctor will ask you to schedule a follow-up visit to inspect your incisions and to see if the surgery was successful.
Outlook (Prognosis) Return to top
This surgery improves the quality of life for most patients. It does not work as well for people who have very heavy armpit sweating. Some people may notice new sweating, but this may go away on its own.
