Evolution of clipping for thoracoscopic sympathectomy in symptomatic hyperhidrosis.
BACKGROUND
Severe hyperhidrosis is treated by thoracic sympathetic chain interrupting through chain transection or clipping. Our study compared the efficacy of these 2 methods.


METHODS
Retrospectively, patients who underwent thoracoscopic sympathectomy from 1999 to 2005 had demographic, operative, and postoperative data analyzed.


RESULTS
Fifty-four operations were performed for refractory sweating of the palm (72%), axilla (66%), foot (53%), and head/neck (19%). Thirty-seven (69%) underwent clipping; 17 (31%) underwent chain transection. There was no difference in age, sex, or blood loss. One ganglion level was interrupted in 24.1% and 2 levels in 75.4%. Bothersome compensatory hyperhidrosis occurred in 13% (5-clipping and 2-transection). One patient underwent clip removal for debilitating symptoms. Three small pneumothoraces occurred (all in the transection group); all treated expectantly.


CONCLUSIONS
Thoracoscopic sympathectomy is a safe outpatient procedure. Both methods yield excellent results with minimal compensatory hyperhidrosis. Thoracoscopic sympathetic chain clipping and transection are equivalent.
