BackgroundCompensatory sweating (CS) is a frequent health concern following treatment of palmar hyperhidrosis using video-assisted thoracoscopic sympathectomy (VATS) and can reduce level of patient satisfaction.MethodsA retrospective cohort study including consecutive patients who underwent VATS for primary palmar hyperhidrosis (HH) over a 5-year period was conducted. Various demographic, clinical, and surgical variables were tested for their correlation to postoperative CS through univariate analyses. Variables with significant correlation to outcome were included in a multivariable logistic regression for determining significant predictors.ResultsThe study included 194, predominantly male (53.6%), patients. About 46% of patients developed CS, mostly during the first month after VATS. Variables with significant correlation (P < 0.05) to CS included age (20 ± 3.6 years), body mass index (BMI) (mean 27 ± 4.9), smoking (34%), associated plantar HH (50%), and laterality of VATS (40.2% in dominant side). Only level of activity showed a statistical trend (P = 0.055). In multivariable logistic regression, BMI, plantar HH, and unilateral VATS were significant predictors for CS. Using receiver operating characteristic curve, the best cutoff point of BMI for prediction was 28.5, with sensitivity 77% and specificity 82%.ConclusionsCS is a frequent health concern early after VATS. Patients with BMI >28.5 and no plantar HH are at higher risk of postoperative CS, and a unilateral dominant side VATS as an initial management step may lessen the risk of CS. Bilateral VATS can be provided for patients with low risk of CS and patients with low satisfaction after unilateral VATS.Copyright © 2023 Elsevier Inc. All rights reserved.
