Which patients are more likely to experience compensatory hyperhidrosis after endoscopic thoracic sympathectomy: a meta-analysis and systematic review

PeerJ. 2025 Mar 18;13:e19097. doi: 10.7717/peerj.19097. eCollection 2025.

ABSTRACT

BACKGROUND: Compensatory hyperhidrosis (CH) is a common consequence of sympathectomy, which can adversely affect patients’ quality of life after surgery. Understanding the factors that influence the occurrence of CH and severe compensatory hyperhidrosis (SCH) is crucial for effective management and counseling of patients undergoing this procedure.

MATERIALS AND METHODS: We registered the protocol in International Prospective Register of Systematic Reviews (CRD42024592389) and following PRISMA guidelines. We searched PubMed, EMBASE, and Web of Science databases for studies published up to September 11, 2024. A systematic literature search identified a total of 10 studies involving 3,117 patients. The primary outcome was the number of CH or SCH. The secondary outcome was the weighted mean difference calculated based on identified related factors. When pooling results or conducting a meta-analysis was not feasible, the study findings were presented in a narrative descriptive format.

RESULTS: The overall incidence of CH was found to be 0.62 (95% confidence interval CI [0.51-0.72]), and four studies totaling 1,618 patients regarding the occurrence of severe compensatory hyperhidrosis, the overall incidence of CH was found to be 0.23 (95% CI [0.12-0.34]). Older age, higher body mass index (BMI) and smoking history correlated positively with CH incidence. In addition, higher BMI level is also associated with the occurrence of SCH (1.20 95% CI [1.01-1.39], p < 0.0001).

CONCLUSION: The findings of this meta-analysis highlight important demographic and lifestyle factors that contribute to the development of CH and SCH following sympathectomy. Older patients, smokers, and those with higher BMI may be at greater risk for these conditions.

Quality of life and compensatory hyperhidrosis following thoracoscopic sympathectomy: a retrospective cohort study

J Cardiothorac Surg. 2025 Mar 21;20(1):160. doi: 10.1186/s13019-025-03393-y.

ABSTRACT

BACKGROUND: Palmar hyperhidrosis (PH), characterized by excessive palm sweating, significantly impacts quality of life (QOL) in affected individuals, particularly young adults. This study aimed to evaluate the efficacy of video-assisted thoracoscopic sympathectomy (VATS) in improving symptoms and QOL among 816 patients with PH.

METHODS: This retrospective study included 816 patients with PH, all of whom underwent VATS under general anaesthesia. One-year follow-up via phone surveys was used to assess symptom changes and side effects. Paired t tests were used to compare pre- and postoperative QOL scores, and linear regression was used to analyse the effects of various factors on QOL changes.

RESULTS: The cohort consisted of 359 males and 457 females, with a mean age of 24.98 ± 6.47 years. All patients underwent VATS, with a 91% success rate, and the mean operative time was 53.2 ± 24.7 min. Postoperative complications included 43 cases of incision infections, 194 cases of chest pain, and 82 cases of pneumothorax; compensatory hyperhidrosis (CH) occurred in 53.80% of the T3 group and 43.74% of the T4 group after one month, with significant differences noted at the 24-month follow-up. Furthermore, the QOL scores significantly improved from 38.25 ± 3.61 preoperatively to 69.07 ± 3.48 at one year postoperatively (P < 0.05).

CONCLUSIONS: VATS offers a reliable and effective treatment for severe PH, significantly enhancing patients’ overall QOL. Future research should focus on long-term outcomes and the applicability of this treatment across diverse populations to further advance the clinical management of PH.

CT-guided Percutaneous Ethanol Sympatholysis for Hyperhidrosis: How I Do It

Radiology. 2025 Mar;314(3):e241430. doi: 10.1148/radiol.241430.

ABSTRACT

Hyperhidrosis, excessive sweating from the eccrine sweat glands, is caused by overactivity of the sympathetic nerves. Facial, axillary, and/or palmar hyperhidrosis (excessive sweating of the face, armpits, and hands) has a reported prevalence of 1%-1.6%. This condition is initially treated conservatively using a combination of topical and pharmacologic treatments. Surgical sympathectomy or percutaneous sympatholysis are treatment options for severe hyperhidrosis (grade 3 or 4) that does not respond to conservative management. The aim of intervention is to permanently disrupt the sympathetic signal by targeting the thoracic vertebral levels T2, T3, and T4 of the paravertebral ganglia, located on the anterolateral surface of the vertebral body. This review presents the step-by-step technique for CT-guided percutaneous ethanol sympatholysis and discusses patient selection for the procedure, potential complications, and treatment outcomes. Although more than 90% of patients report complete resolution of hyperhidrosis immediately after sympatholysis, as many as 40% report symptom recurrence within 6 months. The probability of remaining hyperhidrosis-free long term (ie, more than 6 months) after CT-guided sympatholysis is 60%. Procedural risks include a 15% risk of compensatory hyperhidrosis elsewhere in the body, 8% risk of Horner syndrome (mostly self-limiting), 5% risk of pneumothorax, and 3% risk of severe intercostal neuralgia due to nontarget ethanol deposition. Despite the risks, this intervention can be life-altering for those with severe disease.

Compensatory sweating after thoracoscopic sympathectomy for primary focal hyperhidrosis: a series of 820 cases

Interdiscip Cardiovasc Thorac Surg. 2025 Mar 13:ivaf063. doi: 10.1093/icvts/ivaf063. Online ahead of print.

ABSTRACT

OBJECTIVES: Primary hyperhidrosis is a functionally and socially limiting condition. Thoracoscopic sympathectomy is an effective treatment for hyperhidrosis. However, post-sympathectomy compensatory sweating remains a challenge in clinical practice.

METHODS: Record analysis of patients who underwent thoracoscopic sympathectomy between 2002 and 2020. Emphasis was given to demographic data, site of complaint, functional and social impairment, procedure performed, postoperative results, and compensatory sweating.

RESULTS: A total of 820 patients were included (age 23.8 [7.3] years, body mass index-BMI 22.3 [3.0] kg/m2, 66.3% female). The palmoplantar (44.3%) and palmoplantar-axillary (41.6%) sites were the most affected, followed by the axillary (12.3%) and craniofacial sites (1.8%). On a 0 to 4 scale, functional impairment was significantly greater in the palmoplantar group (p < 0.001) and social impairment in the axillary, palmoplantar-axillary, and craniofacial groups (p < 0.001). The degree of compensatory sweating after surgery was minimal in groups palmoplantar (74.9%), palmoplantar-axillary (70.4%), axillary (63.4%), and mild in the craniofacial group (66.7%). The bivariate analyses showed significant differences in the compensatory sweating variable for age, sex, BMI, and site. The multiple analysis by logistic regression showed BMI, sex, and the palmoplantar-axillary, axillary, and craniofacial variables to be significant for compensatory sweating.

CONCLUSIONS: Thoracoscopic sympathectomy was an effective procedure for controlling primary focal hyperhidrosis, with tolerable compensatory sweating in the patients analyzed in this study.

Systemic effect of sympathectomy in the treatment of localized hyperhidrosis

Updates Surg. 2025 Mar 10. doi: 10.1007/s13304-025-02163-8. Online ahead of print.

ABSTRACT

Hyperhidrosis is thought to result from excessive stimulation of sweat glands due to increased sympathetic activity; however, data on systemic responses following bilateral thoracic sympathectomy as the definitive treatment have not yet been sufficiently evaluated. This study, designed as a prospective cohort investigation, included 24 patients who underwent sympathectomy for palmar and axillary hyperhidrosis at our center in 2023, along with an age-matched control group of equal size. In the sympathectomy group, pupillometry measurements were performed 1 day before surgery and on the 7th postoperative day, while the control group underwent measurements at corresponding intervals. Data from the sympathectomy group were analyzed both preoperatively and postoperatively and compared with the control group. According to the Hyperhidrosis Disease Severity Scale, all patients had severe hyperhidrosis. Sympathectomy was performed at the T3 level in 9 patients and at both T3 and T4 levels in 15 patients. The postoperative satisfaction rate was recorded as 95.8%. No statistically significant differences were observed between preoperative pupillometry measurements of the sympathectomy group and those of the control group. However, when comparing preoperative and postoperative data within the sympathectomy group, significant differences favoring increased parasympathetic activity were noted in the latency of contractions and photopic low values (p = 0.016 and p = 0.038, respectively). Our study is one of the pioneering works to objectively demonstrate, through a quantitative method, that sympathectomy for hyperhidrosis enhances the parasympathetic system response in the ocular region.

Endoscopic thoracic sympathectomy for primary hyperhidrosis: an over a decade-long follow-up on efficacy, impact, and patient satisfaction

J Thorac Dis. 2024 Dec 31;16(12):8292-8299. doi: 10.21037/jtd-24-1407. Epub 2024 Dec 20.

ABSTRACT

BACKGROUND: Endoscopic thoracic sympathectomy is a well-known and effective treatment for palmar and axillary primary hyperhidrosis (PHH). Its most frequent drawback and the main complaint among patients who underwent surgery is the appearance of compensatory sweating (CS). To date, no long-term studies using internationally standardized tools have assessed the efficacy and impact of this surgery on patients. In this study we performed a very long-term follow-up of the patients using an internationally validated tool. The aim of this article is to assess the technique as a treatment for hyperhidrosis, focusing on its long-term efficacy, side effects (CS), and patient satisfaction with the procedure.

METHODS: A closed cohort study was performed conducting a review of the clinical records to identify 100 consecutive patients who underwent bilateral endoscopic thoracic surgery with a minimum follow-up period of 2 years. Patients with diagnoses other than primary palmar or axillary hyperhidrosis or those for whom follow-up was impossible were excluded. A structured telephone survey, including the International Hyperhidrosis Society “Hyperhidrosis Disease Severity Scale” (HDSS) was conducted for all patients. Data were summarized using median (1st and 3rd quartiles) for quantitative variables and relative and absolute frequencies for qualitative variables. To study the likelihood of a patient recommending the surgery, a Bayesian logistic regression model was used reporting results as odds ratio (OR).

RESULTS: A total of 91 patients were included in the follow-up. The median follow-up duration was 10.66 (5.68, 11.98) years. The most affected zone was the hands (29.67%), and the most common sympathectomy levels were R2 and R3 (68.13%). The overall surgical efficacy rate was of 94.50% and CS appeared in 36.26% of the patients, with 75.76% of these cases being mild and severe in only one patient. In total, 97.8% of patients improved their HDSS score after surgery. The OR of recommending the surgery for a lower HDSS index was 0.24 and 0.18 for the apparition of CS. Despite it, 91.21% of patients recommend the surgery, with an overall satisfaction rate of 93.95%.

CONCLUSIONS: Endoscopic thoracic sympathectomy is an effective and safe treatment for palmar and axillary PHH, with a relatively low rate of CS which, when present, is typically mild, making it a highly satisfactory treatment option for patients.

Comparing Compensatory Sweating After Video-Assisted Thoracoscopic Sympathectomy: (T2-3) Versus (T2-4) Levels for Treating Palmar Hyperhidrosis

Cureus. 2024 Nov 20;16(11):e74077. doi: 10.7759/cureus.74077. eCollection 2024 Nov.

ABSTRACT

INTRODUCTION: Primary hyperhidrosis is a disease that is characterized by excessive sweating beyond what is required to maintain the normal temperature of the body. Moreover, it has a great adverse effect on the life of the affected persons because of problems in their social lives. There are different modalities to treat primary hyperhidrosis, including medical and surgical treatment. However, in sympathectomy, there is still a lack of strong evidence regarding which level should be targeted to achieve maximum benefit with fewer complications.

METHODS: This prospective clinical study was conducted at the Cardiothoracic Surgery Department, Alexandria Main University Hospital, Alexandria, Egypt, from September 2021 to Jan 2022. The study involved a total of 50 eligible consecutive patients who had bilateral primary palmar hyperhidrosis managed by bilateral, bi-portal, and tubeless thoracoscopic approach with conventional general anesthesia. Group A represents 25 patients with 13 males (52%) who had sympathetic chain cutting at the level of T2-3, and group B represents 25 patients with 15 males (60%) who had sympathetic chain cutting at the level of T2-4. The effect on palmar hyperhidrosis, compensatory hyperhidrosis, and overall patient satisfaction was assessed on the Visual Analog Scale (VAS).

RESULT: Ninety-eight percent of patients in both groups showed postoperative complete dryness of the hand and improvement of their symptoms. There was a statistically significant (p<0.001) difference regarding the degree of severity of compensatory sweating post-operatively between both groups. In group A, 44% of patients had compensatory sweating, while in group B, 96% of patients had symptoms of compensatory sweating with varying degrees from 1 to 5 on a VAS-Score of five degrees.

CONCLUSION: The level of cauterization has no significant effect on palmar hyperhidrosis dryness after cutting the sympathetic chain at level (T2-3) vs. (T2-4). However, the greater the number of levels that are cauterized, which are three levels rather than two, the more severe the compensatory sweating in this study.

The effects of sympathectomy ganglion levels on late complications in the treatment of hyperhidrosis

J Minim Access Surg. 2024 Nov 29. doi: 10.4103/jmas.jmas_75_24. Online ahead of print.

ABSTRACT

INTRODUCTION: Pathologically excessive sweating in areas such as the palmar, axillary and/or plantar together with sympathetic hyperactivity that occurs independently of systemic causes is called primary hyperhidrosis. Although primary idiopathic hyperhidrosis can be seen at any age, the disease is most commonly seen in adolescents and young adults. The frequency of male and female genders is usually equal. Some medical and minimally invasive methods can be used in the treatment of primary hyperhidrosis. However, the known curative gold standard treatment method for the disease is thoracoscopic thoracic sympathectomy operation.

PATIENTS AND METHODS: In this study, a total of 150 patients who applied to Trakya University Health Practice and Research Center, Department of Thoracic Surgery, between 15 October 2008 and 15 June 2021 and underwent thoracoscopic thoracic sympathectomy due to the diagnosis of hyperhidrosis were evaluated retrospectively. The patients were separated into two groups. Thoracoscopic thoracic sympathectomy was performed on the T2-T4 in the first group (Group I – n : 88) and on the T3-T5 sympathetic ganglions in the second group (Group II – n : 62).

RESULTS: The median age of patients included in the study was found to be 24 (20.75-28) years. Group I and Group II were similar in terms of gender characteristics, but Group II was older. Our success rate was found to be 92% ( n = 138). There was no mortality, major complication such as bleeding requiring open thoracotomy, chylothorax or Horner’s syndrome in any of the patients. Minor complications were seen in the early and late period of the operation at a low rate. Our overall compensatory hyperhidrosis rate was 52% ( n = 78). Compensatory hyperhidrosis was detected more in Group I, although this was not statistically significant. We determined the overall satisfaction rate of our patients as 87.3% ( n = 133). The satisfaction rates of the patients in Group I and Group II were found to be similar.

CONCLUSIONS: Thoracoscopic thoracic sympathectomy is a fast, safe and minimally invasive treatment method with a low complication rate. More than 90% success and a significant increase in psychosocial condition and professional quality of life can be achieved with this procedure. Future studies are needed to reveal the relationship between operated ganglion levels and the development of compensatory hyperhidrosis.

Sexual effects and long-term outcomes of endoscopic lumbar sympathectomy for plantar hyperhidrosis in men: a cross-sectional study

J Vasc Bras. 2024 Sep 27;23:e20240014. doi: 10.1590/1677-5449.202400142. eCollection 2024.

ABSTRACT

BACKGROUND: Plantar hyperhidrosis (PHH) is a disease with high psychosocial impact, and endoscopic lumbar sympathectomy (ELS) has been shown to be the best choice for treatment, but with some concerns such as compensatory sweating (CS) and sexual effects (SE), particularly in men.

OBJECTIVES: The aim of this study is to evaluate the long-term effectiveness of ELS for controlling PHH in men, its side effects, and perceived sexual modifications.

METHODS: A cross-sectional study including only male patients operated for PHH with ELS between 2014-2022 at a private practice. During remote interviews, patients were asked about symptoms before and after ELS and about the postoperative effects on PHH. They were also objectively asked about any SE during the postoperative period. Validated quality of life for hyperhidrosis and erectile function questionnaires were also administered.

RESULTS: 10 male patients averaging 4.26±2.86 years post-ELS were interviewed. Eight of them (80%) achieved complete response (≥80% of sweat reduction) in the first month after surgery and this response was maintained up to the interview date. Two patients had partial response. In six patients, CS occurred, with 5 reporting it as non-troublesome. Six patients reported some type of SE, but none reported erectile dysfunction. Regarding the functional results, all patients rated ELS from good (10%) to very good (30%) or excellent (60%).

CONCLUSIONS: Endoscopic lumbar sympathectomy was effective for treatment of plantar hyperhidrosis in these patients, improving their quality of life and providing lasting PHH control, with some transient sexual dysfunctions that did not impair their sexual life.
