Everyone sweats – but what if you had a condition that caused uncontrollable sweating in your hands?
Palmar hyperhidrosis is a benign condition where individuals experience uncontrollable sweating of their hands, way beyond their physiological needs. Hand sweating in such a scenario is often described as being present 24/7, may be worsened in situations of stress but also occurs out of nowhere in times of total rest and serenity. From the constant dampness the hands are exposed to, ulcerations and other skin related changes may develop. Many patients with this condition adopt a line of work and a life style that minimizes public encounters and avoid hand contact such as having to shake hands.
It has been known since the 1920s that by dividing the sympathetic chain (nerve) high up inside the chest, a procedure called thoracic sympathectomy, we can make the hands stop sweating. To achieve this surgically was quite an undertaking back then. The surgical trauma was such that historically very few individuals with hyperhidrosis opted to have corrective surgery. With the development of videoscopic surgery, however, it has become possible to perform the sympathectomy with minimal trauma to the patients. In addition, the magnification provided by the optics of videoscopic surgery has made the surgery safer.
What is involved in an ETS (Endoscopic Thoracic Sympathectomy)?
Nowadays, we offer surgery under general anesthesia as a day surgical procedure (meaning most patients are expected to go home the day of surgery). Two small incisions are needed, and we preferentially place those on your sides. At Swedish, our preferred approach is to clamp the nerve by placing titanium clips on the nerve at appropriate levels. The advantage of clipping the nerve instead of removing a segment of the nerve (as we did prior to 2005) is for possible reversal of the sympathectomy in the rare instance where a patient may be unhappy with the side effects of the surgery (see below).
What results should I expect?
In our hands, ETS will render the hands dry in 99 to100% of cases ...
