title: An assessment of plantar hyperhidrosis after endoscopic thoracic sympathicolysis.
abstract: BACKGROUND
  Endoscopic bilateral thoracic sympathicolysis (EBTS) is an effective and minimally invasive procedure used for patients with primary hyperhidrosis. The purpose of this study was to examine plantar hyperhidrosis before and after EBTS.
  
  
  METHODS
  A total of 198 patients with primary hyperhidrosis underwent 396 thoracoscopic sympathicolysis of ganglia T2-T3 in a prospective study. All completed a preoperative questionnaire, followed by a second questionnaire 12 months after the operation. The questionnaires evaluated sweating in the different body areas. Only the zones of anhydrosis were considered in delimiting the cutaneous expression of sympathetic ganglia T2-T3.
  
  
  RESULTS
  Redistribution of perspiration as reported by the patients comprised significant reductions in palmar and axillary hyperhidrosis, and an increase in the zone of the trunk and popliteal region. The incidence of plantar anhydrosis and plantar hypohidrosis was 30.3% and 20.7%, respectively (p < 0.001).
  
  
  CONCLUSIONS
  EBTS is followed by redistribution of body perspiration, with, and important, plantar anhydrosis and hypohidrosis. Although EBTS is the standard treatment for palmar primary hyperhidrosis, we must continue studying baseline sympathetic activity in patients affected by primary hyperhidrosis and the neuroanatomy of the sympathetic system to understand the redistribution of sweating and decrease of hyperhidrosis in the zones regulated by mental or emotional stimuli.
