Clinical effect of endoscopic thoracic sympathectomy at different segments on palmar hyperhidrosis and incidence of postoperative compensatory hyperhidrosis

Objective To study the clinical effect of endoscopic thoracic sympathectomy at different segments on palmar hyperhidrosis and research the incidence of postoperative compensatory hyperhidrosis.Methods One hundred palmar hyperhidrosis patients who underwent endoscopic thoracic sympathectomy were divided into 2 groups according to treatment method,the patients in A group (46 cases) received T4 surgery,the patients in B group (54 cases) received T3-4 surgery.The success rate of postoperative,incidence of postoperative compensatory hyperhidrosis and postoperative satisfaction rate between the 2 groups were compared.Results The surgery of 2 groups were successful.There was no statistical difference in total effective rate between the 2 groups (P ＞ 0.05).The incidence of postoperative compensatory hyperhidrosis in A group was significantly lower than that in B group [4.3％ (2/46) vs.20.4％ (11/54)],the postoperative satisfaction rate was significantly higher than that in B group [93.5％(43/46) vs.79.6％ (43/54)],there were statistical differences (P ＜ 0.05).Conclusion Endoscopic thoracic sympathectomy T3-4 or T4 surgery is very effective and safe treatment of palmar hyperhidrosis,but T4 surgery has a lower incidence of postoperative compensatory hyperhidrosis.
