Anxiety after Sympathectomy in patients with primary palmar hyperhidrosis may prolong the duration of compensatory hyperhidrosis.

BACKGROUND

Compensatory hyperhidrosis (CH) is a frequent side effect after sympathectomy for the treatment of primary palmar hyperhidrosis. We determined the effects of demographic and clinical factors which may increase the duration of CH (DCH).

METHODS

One hundred twenty-two patients who had undergone sympathectomies from 2014 to 2016 were retrospectively reviewed. Anxiety was evaluated using the State and Trait Anxiety Inventory score. Follow-up evaluations continued until CH remitted. A Cox proportional hazards model was used to determine the association between DCH and variables.

RESULTS

DCH ranged from 5 to 27 weeks (median, 11.47 weeks). Severe CH (HR = 0.318, 95% CI, 0.136-0.741) and exacerbated anxiety 1 month post-operatively (HR = 0.816, 95% CI, 0.746-0.893) may prolong CH. A positive correlation between post-operative anxiety and DCH was common in patients with moderate or severe CH, and in cases with forearm CH.

CONCLUSIONS

Pre- and post-operative anxiety should be evaluated, and anti-anxiety treatment is offered to patients with moderate-to-severe CH to shorten the DCH.
