Long-Term Effect of Endoscopic Sympathetic Nerve Reconstruction for Side Effects after Endoscopic Sympathectomy

Background Endoscopic thoracic sympathectomy (ETS) is an effective treatment for primary hyperhidrosis. However, compensatory sweating (CS) may occur in many patients. Sympathetic nerve reconstruction (SNR) can be used to counteract severe CS, but the studies on the effects of SNR are few. Patients and Methods Nineteen out of 150 SNR patients were contacted by employing a long-term questionnaire. In this questionnaire, different kinds of sweating were evaluated using a four-graded symptom analysis and the visual analog scale before ETS, after ETS, and after SNR. Results The mean age of the 16 male and 3 female patients at the SNR was 32 years. The mean follow-up was 87 months. According to the long-term questionnaire, the benefit was either excellent (4 patients, 21%), good (3 patients, 15.8%), or reasonable (7 patients, 36.8%) in 14 patients (73.8%), while the benefit was questionable in 1 patient (5.3%). For three patients (15.8%), no benefit was found, and in one patient (5.3%), the situation had deteriorated. Conclusions Improvement in the side effects of ETS after SNR was found in nearly 75% of the patients. This indicates that SNR can be considered as an alternative treatment for patients with severe CS after ETS that is unresponsive to conservative treatment.
