This is “key hole” surgery. This procedure is performed under a general anaesthetic. Two small cuts are made in each armpit 0.5cm in diameter. The sympathetic nerve is divided. The wound is closed with dissolvable sutures. The scar is minimal. The procedure lasts approximately 40 minutes. A post operative chest X-ray confirms full lung expansion.
New Technique for ETS Surgery
This technique can be reversed. Clipping of the sympathetic nerve has been shown to be as effective as conventional ETS surgery in stopping blushing and sweating. It has the advantage in that it can be successfully reversed in 20-30% of cases should it be clinically indicated. the only reason to reverse the surgery is if the side effects are too severe (see results).
Post Operative Course
Often there can be some sharp pain around the wounds and sometimes the upper back, although this soon wears off. Return to work can be as little as 2 days post surgery, but the time can vary depending on the individual. Return to sporting activities can take up to two weeks.
Complications and Side Effects of ETS
In my own experience no life threatening complications have occurred. However, as the “key hole” surgery is performed in the chest there is always a possibility that the chest may be opened in the event of bleeding. NO OPERATION can ever be guaranteed to be 100% safe anywhere. Very rarely there may be an air leak from the lungs which may require a suction drain.
A few patients have prolonged pain or numbness in the arm. Permanent paralysis should not occur.
Horner’s syndrome can occur between 1-3%. This is dropping of the eyelid and a smaller pupil, but no visual impairment. This may be transient or permanent. Wound or chest infection occurs in less than 5%.
One side effect is excessive dryness of the hands. This may require use of moisturising creams. As the sweating is reduced from the head and neck approximately 80% of individuals complain of compensatory sweating elsewhere in the body such as the abomen, legs and feet. This is the body’s way of keeping the internal temperature neutral at 37°C. The degree of compensatory sweating varies upon the individual. Gustatory sweating, which is sweating induced by smells and tastes occur in up to 30% of individuals but very few regard this as a major problem.
Although some patients may feel general fatigue, physical performance has been shown not to be reduced on stress testing despite the heart rate being reduced by 10%.
