Results of endoscopic thoracic sympathectomy (ETS) on hyperhidrosis, facial blushing, angina pectoris, vascular disorders and pain syndromes of the hand and arm

Abstract.

Endoscopic thoracic sympathectomy (ETS) has gained increasing popularity due to its minimally invasive character. Despite the simplicity of the procedure, non-surgical options should always be considered as the first line of treatment. The complication risk of ETS is low but side effects, primarily compensatory sweating (CS) of mainly the trunk, may be severe enough to cause regret of the procedure. The risk/benefit ratio should always be discussed with the patient. Severe palmar hyperhidrosis and facial blushing respond very well to ETS with a high patient satisfaction rate. Facial hyperhidrosis is effectively treated with ETS, but is associated with a high risk for severe CS. Axillary hyperhidrosis is best treated by means other than ETS. The use of ETS for pain syndromes, vascular insufficiency and angina pectoris is not well supported by scientific evidence, making careful patient selection mandatory.
