ObjectiveTo analyze the number of endoscopic thoracic sympathectomies performed to treat hyperhidrosis in the Universal Public Health System of Brazil, the government reimbursements, and the in-hospital mortality rates.BackgroundEven though endoscopic thoracic sympathectomy has been widely performed for the definitive treatment of hyperhidrosis, no series reported mortality and there are no population-based studies evaluating its costs or its mortality rate.MethodsData referring to endoscopic thoracic sympathectomy to treat hyperhidrosis between 2008 and 2019 were extracted from the database of the Brazilian Public Health System, which insures more than 160 million inhabitants.ResultsThirteen thousand two hundred one endoscopic thoracic sympathectomies to treat hyperhidrosis were performed from 2008 to 2019, with a rate of 68.44 procedures per 10 million inhabitants per year. There were 6 in-hospital deaths during the whole period, representing a mortality rate of 0.045%. The total expended throughout the years was U$ 6,767,825.14, with an average of U$ 512.68 per patient.ConclusionsWe observed a rate of 68.44 thoracoscopic sympathectomies for hyperhidrosis' treatment per 10 million inhabitants per year. The inhospital mortality rate was very low, 0.045%, though not nil. To our knowledge, no published series is larger than ours and we are the first authors to formally report deaths after endoscopic thoracic sympathectomies to treat hyperhidrosis. Moreover, there is no other population-based study addressing costs and mortality rates of every endoscopic thoracic sympathectomy for the treatment of any site of hyperhidrosis in a given period.Copyright © 2021 Wolters Kluwer Health, Inc.
