Comparison between high and low levels thoracic sympathectomy for the treatment of palmar and axillary primary hyperhidrosis: systematic review and meta-analysis

ABSTRACT Primary hyperhidrosis (PH) is a condition that has a great impact on affected individuals' quality of life, regardless of its location. Its surgical treatment is done through thoracic sympathectomy performed by videothoracoscopy. Standardization of the technique includes section of the sympathetic trunk at different levels, according to the site of symptoms. The aim of this review is to evaluate the efficacy of thoracic sympathectomy through a systematic literature review comparing sympathectomy at different levels of the sympathetic chain.摘要：原发性多汗症（Primary hyperhidrosis）是一类无论发病部位如何，均会对患者生活质量造成显著影响的疾病。其外科治疗采用电视胸腔镜（videothoracoscopy）辅助下的胸交感神经切除术（thoracic sympathectomy）。该技术的标准化操作规范需根据症状发作部位，在交感干（sympathetic trunk）的不同平面进行切断。本综述旨在通过系统文献综述（systematic literature review）对比不同交感链（sympathetic chain）平面的胸交感神经切除术疗效，以评估该术式的临床有效性。
