title: Transaxillary thoracoscopic sympathectomy experience in a hot climate: management of the dominant hand.
abstract: Primary palmar hyperhydrosis is a functionally and socially disabling problem of unknown etiology, affecting adolescents and young adults, especially in hot climates. Thoracoscopic sympathectomy is the most effective treatment for palmar hyperhydrosis. Postsympathectomy rebound hyperhydrosis may limit its success, especially in hot climates. The aim of this study is to report experience with thoracoscopic sympathectomy in a hot climate, managing the dominant hand (unilateral), followed by the other hand at a later date, based on the patient's choice. One hundred twenty patients were operated on during a 3 year period. The mean operative time was 25 minutes. The procedure was successfully completed in 169 operated limbs and was abandoned in one limb because of severe pleural adhesions. The procedure was done for the dominant hand (unilateral) in 120 patients. Fifty patients returned for contralateral thoracoscopic sympathectomy. There were 18 postoperative complications. Most of the patients (95%) were discharged after an overnight stay. The early observed cure rate was high (97%). During the mean follow-up period of 300 days, there was no recurrence of the original symptoms, except for one patient in whom the nerve of Kuntz was found and diathermized on the second thoracoscopy with symptomatic relief. Rebound hyperhydrosis occurred in 40 patients (33% of the total; 21% in the unilateral group and 42% in the bilateral group). In conclusion, it seems that transaxillary endoscopic sympathectomy of the dominant hand is an alternative method of treatment for patients with hyperhydrosis. Managing the dominant hand first and giving the patient the chance to observe the severity of the rebound hyperhydrosis may facilitate the decision for contralateral sympathectomy.
