title: Long-term results of 630 thoracoscopic sympathicotomies for primary hyperhidrosis: the Vienna experience.
abstract: OBJECTIVE
  To evaluate of the results of thoracoscopic sympathicotomy for upper limb hyperhidrosis with a median observation period of more than 15 years.
  
  
  METHODS
  Retrospective clinical observation study.
  
  
  METHODS
  University-affiliated tertiary referral centre.
  
  
  METHODS
  630 consecutive operations in 352 patients (median age 30.1 yrs) for primary palmar (68%), axillary (12.7%) and combined hyperhidrosis (19.3%).
  
  
  METHODS
  Thoracoscopic sympathicotomy from below T1 to T4 including the fibres of Kuntz using electrocautery through single site access.
  
  
  METHODS
  Perioperative success and complication rates (all patients); long-term follow-up by a questionnaire and/or clinical examination (83.3% of patients) after a median period of 16 yrs. Calculation of statistical significance of differences between groups with c2-test.
  
  
  RESULTS
  67.8% of patients were fully satisfied, 25.7% were partially satisfied and would again agree to the operation. In 93% the procedure cured hyperhidrosis permanently. Compensatory and gustatory sweating was observed in 67% and 47% of cases, respectively. Overall success was significantly (p < 0.001) lower in the group with axillary hyperhidrosis. Main complications: drainage for pneumothorax 1.3%, Horner's syndrome in 3.8%, subcutaneous emphysema 2.1%.
  
  
  CONCLUSIONS
  Thoracoscopic sympathicotomy proved to be highly effective even after long-term follow-up. Compensatory sweating impairs patients' satisfaction in some cases.
