Abstract: Objectives: Video-assisted thoracoscopic sympathectomy (VTS) is effective in treating palmar hyperhidrosis (PH). However, it is no consensus over which segment should undergo VTS to maximize efficacy and minimize the complications of compensatory hyperhidrosis (CH). This study was designed to compare the efficiency and side effects of VTS of different segments in the treatment of PH. Methods: A comprehensive search of PubMed, Ovid MEDLINE, EMBASE, Web of Science, ScienceDirect, the Cochrane Library, Scopus and Google Scholar was performed to identify studies comparing VTS of different segments for treatment of PH. The data was analyzed by Revman 5.3 software and SPSS 18.0. Results: A total of eight randomized controlled trials (RCTs) involving 1200 patients were included. Meta-analysis showed that single segment/low segments VTS could reduce the risk of moderate/severe CH compared with multiple segments/high segments. The risk of total CH had a similar trend. In the subgroup analysis of single segment VTS, no significant differences were found between T2/T3 VTS and other segments in postoperative CH and degree of CH. T4 VTS showed better efficacy in limiting CH compared with other segments. Conclusions: T4 appears to be the best segment for the surgical treatment of PH. Our findings require further validation in more high-quality, large-scale randomized controlled trials.
