OBJECTIVETo evaluate the safety and efficacy of needlescopic thoracic sympathectomy for palmar hyperhidrosis.

METHODSFrom March 2004 to April 2005, 62 patients, including 23 men and 39 women with a mean age of 23 years (ranged from 12 to 53 years), underwent bilateral needlescopic thoracic sympathectomy. Among all the patients 8 cases had accompanied axillary hyperhidrosis. The degree of palmar sweating was moderate in 16 cases and severe in 46 cases. The sympathetic chain on the body of the second and third ribs in all patients was cauterized and divided; the chain on the fourth rib in those with axillary hyperhidrosis was also severed. Intraoperative changes in palmar temperature and blood flow were recorded.

RESULTSSympathectomies were successful, and dry limbs were immediately achieved in all patients after surgery. There were no mortality or life-threatening complication, however 1 patient developed moderate pneumothorax which resolved soon after chest drainage. After all procedures, palmar blood perfusion increased significantly and mean palmar temperature elevated by 2.4 degrees C. The mean operative duration was 65 min, and the mean postoperative hospital stay was 1.2 days. No recurrence of palmar hyperhidrosis occurred after a mean follow-up of 6.3 months (ranged from 1 to 13 months). Compensatory sweating was found in 26 patients, but the symptoms were mostly tolerable and required no further treatment.

CONCLUSIONNeedlescopic thoracic sympathectomy is a safe and effective technique for palmar hyperhidrosis, which is less invasive than conventional video-assisted thoracic surgery.
