Minimally invasive thoracoscopic sympathectomy for palmar hyperhidrosis via a transaxillary single-port approach*1

The aim of this retrospective study was to evaluate the mid-term outcome (average follow-up 10 months, range 6-18 months) and value of transaxillary single-port thoracic sympathectomy using a thoracoscope with an operating channel for the treatment of hyperhidrosis. Between December 1992 and October 2002, 176 consecutive patients (94 men, 82 women, mean age 21 years) with hyperhidrosis underwent thoracoscopic sympathectomy via a 12-mm single-port approach. Data on postoperative morbidity and outcome were analyzed to validate the technique. Mean operative time per side was 9 min; there was no conversion to an open procedure. Ninety-five percent of the patients were discharged the next day. Thirty-day mortality was zero. Complications included unilateral transient Horner's syndrome (n=1), residual pneumothorax requiring chest drainage from the port entry (n=4), and segmental atelectasis of the lung (n=4) which was treated conservatively. Complete relief of symptoms was observed in all patients at the 6-month follow-up; 45% experienced compensatory hyperhidrosis. Single-port thoracoscopic sympathectomy produces excellent medical and cosmetic results in patients with hyperhidrosis, and is associated with a short hospital stay and a low risk of complications. Overall satisfaction is high. A few patients may experience compensatory symptoms.
