[Our experience in the treatment of hyperhidrosis of the upper limbs by video-assisted thoracoscopy: an analysis of our first 100 procedures].

Sympathectomy of the thoracic chain is an effective surgical procedure for treating axillary and palmar hyperhidrosis. The procedure has been performed with minimal invasion and good results in recent years through the use of videothoracoscopic surgery. This paper describes the technique and our experience with a series of 50 patients between 16 and 48 years old. The earliest approach was unilateral in successive operations. The procedure was later performed bilaterally, at first with the patients in sequential lateral decubitus positions and later in semi-seated position. Complications were 1 case of incomplete Claude-Bernard-Horner syndrome that resolved spontaneously two months after surgery; 1 failure when sympathectomy was performed without location of the chain, obliging rapid re-operation; laminar pneumothorax in 12% of the series; compensatory hyperhidrosis in 26%; 10% with chest pain due to intercostal involvement, resolving with time; and slight bleeding in 8%. Outcome was excellent, with complete disappearance of axillary and palmar perspiration. Patient satisfaction was 9.2/10 one year after surgery. Mean hospital stay was less than 36 h.
