[Bilateral video-assisted thoracic sympathicotomy for hiperhidrosis: analysis of 102 patients]

Hyperhidrosis is a disorder consisting of excessive sweating through the different body sweat glands, which produces a negative impact socially and in work-related activities in those that suffer this condition. There are primary and secondary forms. The primary form is a benign condition with excessive sweating mainly in palms, soles of feet, axillae and face. It affects a 1% of the population, and its cause is unknown. Most medical treatments are unsuccessful, and at best, transitory. In patients who are very troubled by the condition, videoassisted bilateral thoracic sympathicotomy has become the elective treatment. In the period ranging from 1998 to 2018, 174 procedures were undertaken for primary hyperhidrosis, of which 102 satisfied the inclusion criteria. 72 patients were excluded. A 20.5% were males, and 79.5% were females, with an average age of 29.22 years at surgery. As to localization of sweating, a 50.9% was palmar-plantar-axillary, 23.5% axillary, 10.7% palmarplantar, 7.8% palmar, 6.8% palmar-axillary, and a 5.8% facial. Those patients with palmar sweating showed a 94.9% improvement, those with axillary sweating a 88.51%, with plantar a 46.25% and those with facial sweating a 84% improvement. The average admission time was 1.1 days. As an undesired effect, compensatory sweating occurred in 53 cases and postoperative complications in 18 cases. We conclude this is a safe technique, that diminishes sweating significantly, improving patient's quality of life.
