Endoscopic thoracic sympathectomy (ETS) — a highly effective keyhole procedure for primary hyperhidrosis affecting the hands, armpits, or face. Over 95% success rate for palmar sweating. Most patients home the same day or the following morning. London Bridge Hospital and Lister Hospital Chelsea.
Primary hyperhidrosis is caused by overactivity of the sympathetic nervous system. Endoscopic thoracic sympathectomy (ETS) is a minimally invasive keyhole procedure that interrupts the relevant segment of the sympathetic chain through a single small incision in the armpit, performed under general anaesthesia.
ETS is most effective for palmar (hand) and facial hyperhidrosis, with published success rates above 95%. The effect is typically immediate — patients wake from surgery with dry hands for the first time in their adult lives.
The main side effect to discuss is compensatory sweating — increased sweating elsewhere on the body, most commonly the trunk. This is mild and acceptable in the majority of patients, though it can be more significant in some. All aspects of the procedure, including risks and realistic expectations, are discussed fully at consultation before any decision is made.
Book a Consultation →ETS is typically performed as a day-case or with a single overnight stay. The procedure takes approximately 30–45 minutes under general anaesthesia. A single small incision is made in each armpit. Most patients return to desk work within 3–5 days and to physical activity within 2 weeks.
