Sympathectomy refers to a medical term by which the sympathetic chain is cut or clamped in order to interfere with its activity. The sympathetic chain is part of the autonomous nervous system. One of its functions is controlling the sweat glands. In patients who have hyperhidrosis, sweat glands are pathologically overactive and hence produce sweat more than the physiological need.

Sympathectomy was performed for the last 50 to 60 years. In the past, it was performed through major incisions in the back, chest wall, or neck. Presently, with endoscopic equipment, one can perform this operation through small incisions with no trauma to muscles or other structures.

In order to treat hyperhidrosis, the surgeon must deal with an overactive sympathetic chain, which is known to be the reason for hyperhidrosis. The main reason for this overactive sympathetic chain is a genetically determined problem. From different studies gathered around the world it is known that about 2/3 of the patients have some family history for hyperhidrosis. As a matter of fact, the term hypersympathetic activity is much more appropriate to use. In this scenario, the nerve is being divided or clipped at a certain level within the chest cavity. At this time, clamping of the nerve at the T3 and T4 level is being practiced by Dr. Reisfeld as the method of choice.

Thanks to developments in the field of endoscopic surgery (surgery that uses small instruments and cameras to allow surgeons entrance into the body with miniscule incisions) this procedure can be performed with only minor discomfort.

The operation is performed on an outpatient basis. The patient is placed under general anesthesia for about one hour – the length of the surgery. Most patients are able to walk out of the medical center within 2 hours after of the surgery. Regular physical activity and return to work are possible in one week or less.

    I suffer from sweaty palms and feet both. Also in general I sweat all over more than normal people. I am excited to read about this surgery but a little skeptical about long term effect and any other side effects. Where can I get information about these?
