A prospective controlled randomized multicenter study to evaluate the severity of compensatory sweating after one-stage bilateral thoracic sympathectomy versus unilateral thoracic sympathectomy in the dominant side.


ABSTRACT: Objective:To evaluate the contribution that unilateral thoracic sympathectomy in dominant side or two-stage bilateral thoracic sympathectomy can have as strategies to reduce the incidence of compensatory sweating after sympathectomy for palmar hyperhidrosis. Methods:This is a prospective, controlled, randomized multicenter trial of 200 participants with palmar hyperhidrosis, which will be randomized into two arms: (a) one-stage bilateral thoracic sympathectomy (control arm); or (b) unilateral thoracic sympathectomy in dominant side (intervention arm). At six months the participants submitted to unilateral procedure can make the contralateral surgery if they wanted it, creating a third group called two-stage bilateral sympathectomy. Participants will be evaluated for the degree of sweating by the Hyperhidrosis Disease Severity Scale (HDSS) and of quality of life questionnaires. Results:96 participants out of the 200 proposed have been included so far, with 48 participants randomized to each arm. From the sample 61 (63.5%) are female, with a mean age of 24 (20-32) years. There were exclusive palmar hiperhydrosis in 14 cases (14.5%), palmar and plantar hyperhidrosis in 36 (37.5%) cases, palmar and axillar hyperhidrosis in 12 (12,5%) cases and palmar-axillary-plantar hyperhidrosis in 34 (35,4%) cases. The age at the beginning of the disease was childhood (78%), with mean of time of disease 15 (11-22) years. Conclusions:If one or both hypothesis: (a) unilateral sympathectomy in dominant hand is a satisfactory treatment; b) two-stage bilateral sympathectomy causes less compensatory sweating than in one stage are confirmed there is a chance that surgical therapy for palmar hyperhidrosis can be changed for better.
