Effectiveness, success rates, and complications of different thoracoscopic sympathectomy techniques in patients with palmar hyperhidrosis.

Abstract

This study aims to investigate the effectiveness, success and complication rates of three different video-assisted thoracoscopic sympathectomy procedures performed for the treatment of primary focal hyperhidrosis; excision, cauterization and clipping. We retrospectively evaluated the records of 60 patients (33 males, 27 females; mean age 25.1±6.4 years; range 16 to 43 years) with primary focal hyperhidrosis and treated with videoassisted thoracoscopic sympathectomy between January 2010 and December 2013. The patients were treated bilaterally at the same session: the sympathetic chain and ganglia were excised from the spinal cord segments of T2-T4 in 20 patients (group 1), cauterized in 20 patients (group 2), and clipped in 20 patients (group 3). The procedural success and complication rates were compared among the groups. Sympathectomy was successfully performed in all patients. The mean operation time was found to be significantly shorter in group 2 (42.5±7.1 min) and group 3 (36.9±7.8 min), compared to group 1 (51.1±8.4 min) (p<0.05). Compensatory hyperhidrosis developed in 17 patients (28.3%) and was comparable among all groups (p<0.05). Our study results suggest that excision, cauterization, and clipping are effective and reliable in the treatment of primary focal hyperhidrosis. Based on our experience, we believe that sympathectomy with video-assisted excision may be preferable for the treatment of primary focal hyperhidrosis.
