title: Long-term results of thoracoscopic sympathectomy for hyperhidrosis.
abstract: BACKGROUND
  Thoracoscopic sympathectomy is now the reference treatment for severe palmar hyperhidrosis, but this is offset by the occurrence of compensatory sweating. It has been studied in this series to improve the indications and information given to patients.
  
  
  METHODS
  A retrospective review of 124 patients who were previously afflicted with bilateral thoracoscopic sympathectomy 6 years earlier was conducted. Patients were interviewed by postal questionnaire regarding the results and side effects.
  
  
  RESULTS
  The series consisted of 89 females (72%) and 35 males and the mean age was 28 years. The main indication was palmo-plantar hyperhidrosis (34%). The mean operating time was 36 minutes and there were no intraoperative complications. Postoperative pneumothorax occurred in 9 patients and 3 patients required a chest drain. The hospital stay was 36 hours for 87.6% of the patients. Postoperative pain occurred in 78% of the patients. Neurologic complications (Horner syndrome, radial paralysis, and dysesthesia of the arm) occurred in 3 patients and disappeared after 2-6 months. Two patients required single-side reoperation because of failure with the first intervention. Eighty-nine replies to questionnaires were received (72%). The results for hands were favorable in 98% and in 63% for axillae. Compensatory sweating occurred in 87% of the patients (serious in 36% and incapacitating in 6%). Despite this 90% of the patients were satisfied or very satisfied.
  
  
  CONCLUSIONS
  This study confirms that thoracoscopic sympathectomy is a suitable method of treatment for severe palmar hyperhidrosis but emphasizes the need to offer the patient more informative information, especially regarding compensatory sweating which seems inescapable.
