Randomized and self-controlled study of palmar hyperhidrosis treated by sympathectomy at different segments under thoracoscope

Objective To observe the curative effects and post-operative compensatory hyperhidrosis of sympathectomy at different segments for palmar hyperhidrosis under thoracoscope. Methods Fifty-six patients with palmar hyperhidrosis were performed with sympathectomy under thoracoscope. Position of the sympathectomy of two sides( T3 or T4) was randomly decided before operation. Results Operation was successfully performed on all patients,and their palmar hyperhidrosis was completely alleviated after operation. No surgery-related post-operative complication occurred. The incidence of light-moderate compensatory hyperhidrosis was 39. 3% in T3 group,and 19. 6% in T4 group( χ2= 4. 76,P 0. 05),and no severe compensatory hyperhidrosis was recorded. Conclusions Occurrence rate of compensatory hyperhidrosis is lower in T4 resection than in T3.
