Abstract
Background: Primary focal hyperhidrosis (PFH) is associated with autonomic nervous activity, and studies investigating this association in patients with PFH are very important. Heart rate variability (HRV) is a simple and noninvasive electrocardiographic test showing activity and balance in the autonomic nervous system, which consists of sympathetic and parasympathetic components. The aims of this study are to investigate associations between autonomic nervous activity and hyperhidrosis characteristics using HRV and to investigate the association between HRV findings and compensatory hyperhidrosis (CH) after sympathectomy.
Methods: From March 2017 to March 2020, 105 subjects with PFH who underwent preoperative HRV tests and sympathectomy were analyzed. All subjects underwent bilateral thoracoscopic sympathectomy. T2 sympathectomy was conducted for craniofacial hyperhidrosis, and T3 sympathectomy was conducted for palmar hyperhidrosis. The following HRV parameters chosen to investigate the association between hyperhidrosis and autonomic nervous activity were measured by time and frequency domain spectral analysis: (I) time domain: standard deviation of normal-to-normal interval (SDNN) and square root of mean squared differences of successive normal-to-normal intervals (RMSSD), (II) frequency domain: total power (TP) of power spectral density, very low frequency (VLF), low frequency (LF), and high frequency (HF). HRV parameters were analyzed according to hyperhidrosis type (craniofacial vs. palmar type), sweat reduction, and CH after sympathectomy. In addition, the independent HRV parameters influencing CH after sympathectomy were investigated with multivariate analysis.
Results: Craniofacial hyperhidrosis was significantly more prevalent in the old age group (P<0.001). Sweat reduction after sympathectomy was significantly more prominent in palmar hyperhidrosis (P=0.037), and CH after sympathectomy was more prominent in craniofacial hyperhidrosis (P<0.001). Palmar type patients exhibited significantly larger SDNN, RMSSD, TP, LF, and HF than craniofacial type patients (all P<0.001). There were no significant differences in any HRV parameters according to sweat reduction after sympathectomy. Low-degree CH was associated with significantly larger SDNN, RMSSD, TP, LF, and HF than high-degree CH (P<0.001, P<0.001, P=0.002, P=0.001, and P<0.001, respectively). Multivariate analysis showed that HF and age group were associated with CH after sympathectomy (P=0.007 and P=0.010, respectively).
Conclusions: This study shows that HRV can provide useful insight into the pathophysiology of PFH and enhance preoperative risk stratification of CH. Large-scale, prospective studies are required to determine the predictive value of HRV in patients at risk for subsequent CH after sympathectomy.

Abstract
Excessive sweating in the hands, feet, and armpits is a difficult problem for people who suffer from it and is an increasingly frequent reason for consulting a thoracic surgeon. The existing medical treatments are only palliative, so primary hyperhidrosis is a definite indication for thoracic sympathectomy. This video tutorial shows in detail the 2-port videothoracoscopic surgical technique performed by our surgical team.

Abstract
Compensatory hyperhidrosis is a debilitating postoperative condition occurring in 30% to 90% of patients with primary hyperhidrosis. The most appropriate treatment for compensatory hyperhidrosis remains controversial.Between January 2018 and December 2019, 44 patients with intractable compensatory hyperhidrosis underwent diffuse sympathicotomy (DS). In the early study periods, DS was performed sparsely (limited DS) to avoid possible adverse effects (right R5/7/9/11, left R5/6/8/10). In the late study periods, levels of surgical interruption were further modified to maximize sympatholytic effects (extended DS; bilateral R5/6/7/8/9/10/11). Patients were followed up for symptom resolution. For objective evidence of improved hyperhidrosis, thermographic images were taken for 7 patients.Immediate resolution of compensatory hyperhidrosis was achieved in 81% of patients, as determined at the 1 to 2 week postoperative visit. With a median follow-up of 22.7 months, compensatory hyperhidrosis continued to be resolved in 46% (n = 20). Logistic regression analysis showed that persistent resolution of compensatory hyperhidrosis was independently predicted by extended DS (odds ratio, 25.67, 95% CI, 1.78-1047.6; P = .036). The presence of gender, BMI, isolated compensatory hyperhidrosis, distribution of sweating, prior operation type, reoperation interval, and same-day lumbar sympathectomy failed to gain statistical significance on maintaining persistent resolution of compensatory hyperhidrosis. No patients experienced surgery-related side effects. Thermographic images obtained before/after surgery in 10 patients showed successful denervation and sweat diminishment.This study shows the safeness and effectiveness of DS for treating compensatory hyperhidrosis, representing a new treatment option. Future research should be directed at confirming a promising result of extended DS with further follow-up.

Abstract
Background: Primary hyperhidrosis is a functionally and socially disabling condition resulting in social embarrassment and low quality of life. Thoracic sympathectomy is a definitive choice of treatment with favorable results. However, patients may face another embarrassing condition following surgery as compensatory hyperhidrosis which has no definitive treatment. The predictors of compensatory hyperhidrosis are controversial and remain unclear.
Patients and methods: A total of 74 patients underwent a videothoracoscopic sympathectomy for primary hyperhidrosis. We statistically analyzed our patients with correlations and uni-multivariate logistic regression models to outline the possible predictors of compensatory hyperhidrosis.
Results: A total of 45 (60.8%) patients had compensatory hyperhidrosis. The correlations showed that patients, with age greater than 21 years (P = 0.018), with body mass index (BMI) greater than 22 kg / m2 (P = 0.045), with isolated facial hyperhidrosis (P = 0.044), and with smoking status (P = 0.015), had significantly greater rates of compensatory hyperhidrosis. Similarly, the significant univariate predictors of compensatory hyperhidrosis were age > 21 (P = 0.020), BMI > 22 kg / m2 (P = 0.048), and the presence of smoking status (P = 0.015). Multivariate analysis revealed only smoking as a predictor within the threshold of significance (P = 0.078).
Conclusion: The clinical predictors of compensatory hyperhidrosis following a thoracic sympathectomy appear as older age, greater body mass index, and smoking.

Abstract
INTRODUCTION: Hyperhidrosis is a disorder of excessive and uncontrollable sweating beyond the body’s physiological needs. It can be categorised into primary or secondary hyperhidrosis based on its aetiology. Detailed history review including onset of symptoms, laterality of disease and family history are crucial which may suggest primary hyperhidrosis. Secondary causes such as neurological diseases, endocrine disorders, haematological malignancies, neuroendocrine tumours and drugs should be adequately examined and investigated prior to deciding on further management. The diagnosis of primary hyperhidrosis should only be made only after excluding secondary causes. Hyperhidrosis is a troublesome disorder that often results in social, professional, and psychological distress in sufferers. It remains, however, a treatment dilemma among some healthcare providers in this region.
METHODS: The medical records and clinical outcomes of 35 patients who underwent endoscopic thoracic sympathectomy for primary hyperhidrosis from 2008 to 2018 in Department of Cardiothoracic Surgery were reviewed.
RESULTS: The mean age of the patients was 27±10.1years, with male and female distribution of 18 and 17, respectively. Fifty-one percent of patients complained of palmar hyperhidrosis, while 35% of them had concurrent palmaraxillary and 14% had palmar-plantar-axillary hyperhidrosis. Our data showed that 77% (n=27) of patients were not investigated for secondary causes of hyperhidrosis, and they were not counselled on the non-surgical therapies. All patients underwent single-staged bilateral endoscopic thoracic sympathectomy. There was resolution of symptoms in all 35 (100%) patients with palmar hyperhidrosis, 13(76%) patients with axillary hyperhidrosis and only 2 (50%) patients with plantar hyperhidrosis. Postoperatively 34.3% (n=12) of patients reported compensatory hyperhidrosis. There were no other complications such as pneumothorax, chylothorax, haemothorax and Horner’s Syndrome.
CONCLUSION: Clinical evaluation of hyperhidrosis in local context has not been well described, which may inadvertently result in the delay of appropriate management, causing significant social and emotional embarrassment and impair the quality of life of the subjects. Detailed clinical assessment and appropriate timely treatment, be it surgical or non-surgical therapies, are crucial in managing this uncommon yet distressing disease.

Abstract
Introduction: Thoracoscopic sympathectomy (TS) has been proven to be a safe and effective treatment for primary palmar hyperhidrosis (PH). However, the complications include compensatory hyperhidrosis (CH), and over-dry hands may occur in some patients after TS.
Aim: To compare the therapeutic effect of T3 and T4 TS on primary PH and primary PH with axillary and plantar sweating.
Material and methods: We retrospectively analyzed 100 patients with PH who had undergone T3 (group A, n = 49) or T4 (group B, n = 51) TS in our department, with at least 1 year of postoperative follow-up.
Results: At discharge, no major complications or deaths occurred in either group. The condition of sweaty hands was fully improved in 44 of 49 patients in group A and all patients in group B, with a significant difference (p = 0.031). After 12 months of follow-up, 18 (36.7%) patients in group A and 4 (7.8%) patients in group B developed CH, 16 (48.5%) patients in group A and 24 (77.4%) patients in group B had improved axillary sweating, with a significant difference (p < 0.05). The satisfaction rate of group B was significantly higher than that of group A (p < 0.01).
Conclusions: Both T3 and T4 TS were safe and effective treatments for PH patients, but the incidence of CH in T4 TS was lower than that in T3 TS. T3 TS may be more suitable for patients with severe PH, while T4 TS had a better therapeutic effect on PH patients with axillary sweating.

Abstract
Background: Hyperhidrosis is due to the hyperactive autonomic stimulation of the sweat glands in response to stress. Primary hyperhidrosis is a common yet psychologically disabling condition. This study will describe our experience in managing hyperhidrosis via endoscopic thoracic sympathectomy (ETS). Methods: The information was obtained from the patient records from 1 st January 2011 until 31 st December 2016. Pertinent information was extracted and keyed into a study proforma. Results:  150 patients were operated on but only 118 patients were included in this study. The mean age was 22.9±7.3 years. The majority (54.2%) had palmar-plantar hyperhidrosis and 39.8% had associated axillary hyperhidrosis. Excision of the sympathetic nerve chain and ganglia were the main surgical technique with the majority (55.9%) at T2-T3 level. Mean ETS procedure time was 46.6±14.29 minutes with no conversion. Surgical complications were minimal and no Horner’s Syndrome reported. Mean hospital stay was 3.5±1.05 days. The majority of patients (67.8%) had only one follow-up and only half of the study sample (58.5%) complained mild to moderate degree of compensatory sweating, even though the long-term resolution is yet to be determined by another study. Following ETS, 98.3% of patients had instant relief and resolved their palmar hyperhidrosis. Predictors of CS were sympathectomy level and follow-up. The odds of reporting CS was 2.87 times in patients undergoing ETS at the T2-T3 level compared to those undergoing ETS at the T2-T4 level. The odds of reporting CS was 13.56 times in patients having more than one follow-up compared to those having only one follow-up. Conclusion: We conclude that ETS is a safe, effective and aesthetically remarkable procedure for the treatment of primary hyperhidrosis  with only half of the patients developing mild to moderate degree of CS. Significant predictors of CS were sympathectomy level during ETS and frequency of follow-up after ETS.

Abstract
OBJECTIVE: This video is a step-by-step description of thoracoscopic sympathectomy.
INDICATION: Sweating is essential for thermoregulation. Hyperhidrosis is a condition of excess sweating from the eccrine glands and is associated with severe suffering for patients of all ages. It often worsens during adolescence. A generalised and focal type of hyperhidrosis which affects mainly the face, armpits, hands and feet can be distinguished from the focal variant. Thoracic sympathectomy has become the standard treatment for palmar and axillary hyperhidrosis worldwide.
METHODS: The procedure is performed in the supine position with the upper body elevated about 30° in an adolescent patient. Both arms are abducted at 90° and single tube endotracheal ventilation is employed. A 3 mm trocar is placed in the anterior axillary line for a 3 mm 30° optic. A 5 mm trocar placed on the anterior axillary line (or breast fold in female patients) of the 4th or 5th intercostal space is used for the bipolar forceps. The sympathetic trunk and ganglia T 2 - 4 are identified and coagulated over the heads of ribs.
CONCLUSION: The thoracoscopic approach to focal palmar and axillary hyperhidrosis allows clear identification of the sympathetic structures on each side. Under direct vision, selective ablation of the ganglia and sympathetic trunk provides long-term benefit for patients.

Abstract
Compensatory hyperhidrosis (CH) is the most frequent complication after thoracic sympathectomy (TS) applied in the treatment of localized hyperhidrosis. It affects the quality of life in patients, especially in social, professional and affective spheres. The present study aims to describe the operative technique of bilateral TS from R5 to R8 by videothoracoscopy as an optimized resolution of CH. R5-R8 technique allows shorter surgical time, better ergonomics, more satisfactory aesthetic outcome and reduction of postoperative morbidity. Severe CH treatment remains a challenge.

Abstract
Background: Endoscopic thoracic sympathectomy (ETS) has not been widely adopted for treating craniofacial hyperhidrosis (CFH) due to its known postoperative complication, compensatory hyperhidrosis (CH). In this study, we evaluated whether the autonomic nerve analysis data via pre-ETS heart rate variability (HRV) test can predict post-ETS CH in patients with CFH.
Methods: From October 2017 to March 2019, we consecutively included CFH patients who underwent ETS and received preoperative HRV. In this prospective observational study, we evaluated those who developed CH 3 months postoperatively. The CH grades were categorized into none, mild, moderate, and severe.
Results: A total of 53 patients were included; the mean age was 42.5±13.2 years, and there were 41 males (77.4%). Twenty-six (49.1%) patients had a post-ETS CH grade of greater than moderate (moderate and severe). We further classified the group into trivial and serious compensation, based on the CH grade for comparison. Among the various HRV values, low frequency/high frequency (LF/HF) value was the only one that achieved statistical significance (P=0.025). Moreover, among those in the trivial compensatory group, 23 (85.2%) patients had an LF/HF value between 0.66 and 2.60, and therefore, were included in the autonomic balanced group. On the other hand, among those in the serious compensatory group, 24 patients (92.3%) had an LF/HF value of less than 0.66 and greater than 2.60, and thus, in the autonomic dysfunction group.
Conclusions: According to the present study, HRV test, especially the HF/LF value, appears to be a useful test in predicting post-ETS serious CH.
