title: Thoracoscopic sympathectomy for palmaris hyperhidrosis.
abstract: BACKGROUND
  Palmaris hyperhidrosis is a disorder mediated by the sympathetic nervous system. It causes excessive sweating. This study evaluated the safety, efficacy, and outcome after thoracoscopic sympathectomy in patients with palmaris hyperhidrosis.
  
  
  METHODS
  We reviewed the medical records of 18 patients (10 male) who underwent bilateral thoracoscopic sympathectomy between July 1998 and June 2001.
  
  
  RESULTS
  The patients' mean age was 34 years. No conversions to thoracotomy occurred. Three 2- to 5 mm trocars were used. The thoracic sympathetic chain was resected from ganglia T2-T4, except in one patient with axillary hyperhidrosis requiring resection to T5. The mean operating time was 112 minutes, the mean blood loss was 50 ml, and the mean postoperative hospital stay was 1.2 days. Two patients had a unilateral pneumothorax requiring tube thoracostomy; one patient developed a chest wall hematoma at a trocar site that resolved without treatment, and one patient developed a transient unilateral Horner's syndrome. There have been no hospital readmissions. After a mean follow-up period of 14 months, 11 patients (56%) reported compensatory sweating. Sixteen patients (89%) were satisfied with their outcomes. One patient was dissatisfied because of excessive compensatory sweating, and another continues to have mild unilateral sweating on one hand and compensatory sweating of the face.
  
  
  CONCLUSIONS
  Thoracoscopic sympathectomy is a safe and effective alternative treatment for palmaris hyperhidrosis. Compensatory sweating occurs in more than 50% of patients but is tolerable in most. The majority of patients are satisfied with their short-term outcomes.
