title: Efficacy and safety of thoracoscopic sympathicotomy for hyperhidrosis of the upper limb. Results of 734 sympathicotomies.
abstract: BACKGROUND
  Thoracoscopic sympathicotomy (TS) evolved as treatment of choice in severe hyperhidrosis. The aim of this study was to assess the role of video-assistance in TS (VATS) versus conventional TS (CTS) for primary hyperhidrosis of the upper limb with regard to safety, side-effects and long-term outcome.
  
  
  METHODS
  734 TS were performed from below T1 to T4 in 406 patients. In the CTS and in the VATS group 558 and 176 procedures were performed, respectively. Follow-up was completed in 82% of all patients after a median observation period of 16 years.
  
  
  RESULTS
  Dry limbs were immediately achieved in 92% (CTS) and 97% (VATS, p = 0.98). Only one patient (CTS) underwent conversion due to bleeding. In the CTS group Horner's syndrome occurred in 2.2% and rhinitis in 9.9% of procedures. No patient of the VATS group experienced Horner's syndrome (p = 0.025), 3 patients developed rhinitis (p = 0.11). At follow-up compensatory sweating was observed in 67.6% vs. 55.6% (p = 0.051) and gustatory sweating in 50.4% and 33.3% (p = 0.01). There were 5 failures or recurrences (1.9%) in the CTS group and 2 (2.8; p > 0.05) in the VATS group at reevaluation. Overall 6.5% (CTS) and 5.6% (VATS) of patients regret the operation (p = 0.7).
  
  
  CONCLUSIONS
  We observed a significant decrease of the incidence of complete or incomplete Horner's syndrome and gustatory sweating when the procedure was guided by video-imaging while success rate was similar when compared with CTS.
