J Laparoendosc Adv Surg Tech A. 2025 Dec 12. doi: 10.1177/10926429251405812. Online ahead of print.

ABSTRACT

Background: Primary hyperhidrosis is a debilitating condition characterized by excessive focal sweating, most commonly affecting the axillae, palms, and soles, for which surgical intervention provides a durable solution in patients refractory to medical management. Methods: We present our outpatient surgical technique for video-assisted thoracoscopic sympathectomy (VATS) using a two-port, 3-mm incision approach and evaluate its efficacy and outcomes. A case series of 33 consecutive patients undergoing outpatient VATS sympathectomy between 2016 and 2023 was reviewed, with 9 patients excluded for lack of postoperative follow-up. All procedures were performed with electrocautery at the third and fourth ribs posteriorly (T3 and T4). Results: The technique demonstrated consistent efficacy in symptom resolution with short operative times, low postoperative pain, and rapid recovery. Mean operative time was 22.0 ± 3.7 minutes, with same-day discharge achieved in all patients. The average pain score at discharge was 2.0 ± 2.6, and no intraoperative or immediate postoperative complications occurred. Symptom severity scores improved across all regions, most notably in the palms (8.8 ± 2.1 to 1.3 ± 2.1, P < .001) and axillae (7.1 ± 2.9 to 2.2 ± 2.3, P < .001), with improvement also observed in plantar sweating (8.6 ± 2.0 to 4.8 ± 3.0, P < .001), while facial sweating showed a modest, nonsignificant change (2.3 ± 2.8 to 1.5 ± 2.2, P = .21). At 2-4 weeks, complication rates, including compensatory hyperhidrosis and pneumothorax, were comparable to conventional methods. Conclusion: This minimally invasive two-port VATS sympathectomy with 3-mm incisions appears safe, effective, and patient-centered, supporting its use as a surgical approach for primary hyperhidrosis.

Compensatory hyperhidrosis following endoscopic thoracic sympathectomy: a 5-year follow-up study of risk factors and symptom progression

J Cardiothorac Surg. 2025 Dec 8. doi: 10.1186/s13019-025-03720-3. Online ahead of print.

ABSTRACT

BACKGROUND: Compensatory hyperhidrosis (CH) is a common complication after endoscopic thoracic sympathectomy (ETS) for hyperhidrosis. Despite its prevalence, long-term data on CH progression and associated risk factors are scarce. This study aimed to evaluate the risk factors and progression of CH during a 5-year follow-up period.

METHODS: This study retrospectively analyzed 138 patients with primary palmar hyperhidrosis (PPH) who underwent endoscopic thoracic sympathectomy between January 2014 and December 2019. All patients received bilateral single-port thoracoscopic sympathectomy and were followed up at 1, 3, and 5 years postoperatively. The severity of postoperative sweating was assessed using the Hyperhidrosis Disease Severity Scale (HDSS). Univariate and multivariate logistic regression analyses were performed to identify risk factors associated with the development and progression of CH.

RESULTS: A total of 138 patients were included in the study, with 78.9% reporting the occurrence of CH after surgery and 23.8% of them experiencing severe CH. HDSS scores gradually increased over the 5-year postoperative period, indicating symptom worsening. Further analysis revealed that bilateral R4-level sympathectomy significantly increased the risk of CH progression (OR = 4.28, 95% CI: 1.27-15.60, P = 0.021) while having three or more affected areas was identified as a protective factor (OR = 0.19, 95% CI: 0.05-0.63, P = 0.008).

CONCLUSION: This study found that compensatory hyperhidrosis is relatively common in patients undergoing ETS, and symptoms may progressively worsen over time. The level of sympathetic nerve resection and the number of affected areas are key predictive factors for symptom progression.

Scar-concealed 2 + 3 mm dual-port thoracoscopic sympathectomy for palmar hyperhidrosis: single-center outcomes

Front Surg. 2025 Oct 24;12:1664901. doi: 10.3389/fsurg.2025.1664901. eCollection 2025.

ABSTRACT

OBJECTIVE: To minimize the trauma and incision of the operation for primary palmar hyperhidrosis (PPH), we have designed a inconspicuous scar thoracoscopic bilateral thoracic sympathetic chain transection via “2 + 3 mm” two-pinhole incisions (ISTTST). This study mainly retrospectively compares and analyzes the pros and cons of this surgical method vs. the conventional single-port thoracoscopic sympathetic nerve transection (CSTTST).

METHODS: Data of patients with moderate or severe PPH and underwent thoracic sympathetic chain transection were collected. Patients undergoing ISTTST and those receiving CSTTST were included in the two-pinhole group and the single-port group respectively. The baseline characteristics, intraoperative and postoperative conditions of the two groups were compared.

RESULTS: A total of 265 patients were enrolled, including 162 in the single-port group and 103 in the two-pinhole group. There were no statistically significant differences in baseline conditions such as gender, age, BMI, age of onset of PPH, hyperhidrosis sites, hyperhidrosis degree, and transection level of thoracic sympathetic chain between the two groups (P > 0.05). The two-pinhole group had shorter operation time (19.809 ± 3.356 min vs. 22.534 ± 4.541 min), lower postoperative incision pain score (1.563 ± 0.518 vs. 2.012 ± 0.788), and better incision satisfaction (9.437 ± 0.498 vs. 8.068 ± 1.424) (all P < 0.001). There were no statistically significant differences in postoperative conditions such as surgical effect, 24-h postoperative discharge rate, postoperative complication rate, postoperative compensatory hyperhidrosis, postoperative recurrence rate of PPH, and postoperative follow-up time between the two groups (P > 0.05).

CONCLUSION: The ISTTST is a more concealed-scar, minimally invasive, and convenient procedure, meeting the aesthetic needs. Compared with the CSTTST, it has certain advantages and deserves more attention and attempts.

Pleural effusion following thoracoscopic sympathectomy in a patient with palmar hyperhidrosis

BMC Pulm Med. 2025 Oct 2;25(1):446. doi: 10.1186/s12890-025-03933-1.

ABSTRACT

Thoracoscopic sympathectomy can be used to treat primary hyperhidrosis (PH). Nonetheless, there is a paucity of literature addressing the postoperative complications associated with this procedure. We report a case of a 21-year-old male patient who developed prolonged bilateral pleural effusion after undergoing thoracoscopic sympathectomy for PH. This case aims to raise awareness of this rare complication and discuss effective management strategies for it.

Unilateral versus Bilateral T3 Ganglionectomy in Primary Palmar Hyperhidrosis Patients

Thorac Cardiovasc Surg. 2025 Sep 11. doi: 10.1055/a-2699-8163. Online ahead of print.

ABSTRACT

BACKGROUND: Primary palmar hyperhidrosis (PPH) is a distressing condition that significantly impairs quality of life. Endoscopic thoracic sympathectomy (ETS) is an effective treatment, but compensatory hyperhidrosis (CH) remains a common and problematic complication. The optimal extent of surgical interruption, particularly the choice between unilateral and bilateral ganglionectomy, remains uncertain.

METHODS: We conducted a retrospective analysis of 118 patients who underwent unilateral (n=41) or bilateral (n=77) T3 ganglionectomy via video-assisted thoracoscopic surgery (VATS) between November 2023 and January 2025. Patient-reported outcomes, including CH and postoperative satisfaction, were assessed three months postoperatively using standardized questionnaires. Comparisons between the two groups were performed using t-tests and chi-square tests.

RESULTS: Baseline demographics were comparable between groups. The unilateral group reported significantly higher satisfaction, with 93% “very satisfied” compared to 61% in the bilateral group (p<0.001). CH was less prevalent in the unilateral group (20% vs. 48%, p=0.007), and when present, was generally mild and limited to a single body region. In contrast, bilateral ganglionectomy was associated with more frequent and multi-regional CH. Among unilateral ETS patients, only 22% later underwent contralateral surgery, indicating that unilateral intervention was sufficient in most cases.

CONCLUSIONS: Unilateral T3 ganglionectomy offers a favorable balance of efficacy and safety, yielding higher satisfaction and significantly reduced CH compared to bilateral procedures. These findings support the use of unilateral ETS as a first-line surgical strategy for PPH, particularly in patients sensitive to CH. A tailored, staged approach may enhance long-term outcomes and patient satisfaction.

Efficacy and Safety of Treatments for Primary Palmar Hyperhidrosis: A Systematic Review Assessing Patient-Centric Outcomes

Dermatol Res Pract. 2025 Aug 20;2025:8867838. doi: 10.1155/drp/8867838. eCollection 2025.

ABSTRACT

Background: Primary palmar hyperhidrosis (PH) is a chronic condition characterized by excessive sweating in the palms, significantly affecting the quality of life (QOL) of affected individuals. Despite the availability of various treatment modalities, the long-term efficacy and safety of these interventions remain unclear, warranting a comprehensive evaluation. This systematic review aims to assess the efficacy, safety and patient-reported outcomes of treatments for PH. Methods: A systematic search was conducted in PubMed, Embase and the Cochrane Library from their inception until March 2024, adhering to PRISMA guidelines. Inclusion criteria focused on prospective and retrospective studies examining PH treatments published in English. Data from eligible studies were extracted, analysed qualitatively and reported based on outcomes, including efficacy, QOL improvements and adverse effects. Results: Fourteen studies, including 1733 patients aged 4-77 years, were included in the final review. The treatments assessed included oral and topical oxybutynin, iontophoresis, botulinum toxin A injections, photodynamic therapy (PDT) and endoscopic thoracic sympathectomy (ETS). Oral oxybutynin demonstrated symptomatic relief in 60%-97% of the patients although anticholinergic side effects were frequently reported. ETS, while providing the highest rates of complete sweat cessation, was associated with compensatory hyperhidrosis. Noninvasive treatments like iontophoresis showed moderate efficacy with minimal side effects but required ongoing sessions for maintenance. Conclusion: This review highlights the efficacy of several therapeutic approaches for PH though most treatments are hindered by significant adverse effects or practical limitations. Future research should prioritize long-term studies and standardized outcome measures to guide clinical decision-making more effectively.

Effect of Radiofrequency Ablation and Comparison With Surgical Sympathectomy in Palmar Hyperhidrosis

Cureus. 2025 Jul 22;17(7):e88543. doi: 10.7759/cureus.88543. eCollection 2025 Jul.

ABSTRACT

BACKGROUND: Palmar hyperhidrosis is a distressing condition characterized by excessive palm sweating that significantly impacts patients’ quality of life (QoL). Radiofrequency ablation (RFA) and surgical sympathectomy are effective treatment modalities. This study aims to evaluate and compare the effectiveness, patient satisfaction, and safety profiles of RFA and surgical sympathectomy in managing palmar hyperhidrosis.

METHODS: This retrospective study included 91 patients diagnosed with primary palmar hyperhidrosis who underwent either RFA or surgical sympathectomy. The primary outcome was the reduction in sweating severity. Statistical analyses were performed to compare treatment outcomes between the two groups.

RESULTS: Both RFA and surgical sympathectomy significantly reduced Hyperhidrosis Disease Severity Scale scores; however, surgical sympathectomy demonstrated greater symptom reduction at six months (p = 0.01) and 12 months (p = 0.002). Patients in the sympathectomy group reported a longer symptom relief duration (11.8 ± 3.1 vs. 9.2 ± 2.5 months, p = 0.003) and greater improvement in QoL scores at 12 months (p = 0.02). The incidence of compensatory sweating was higher in the sympathectomy group (34.0%, n = 16 vs. 18.2%, n = 8, p = 0.08), whereas recurrence of hyperhidrosis was more frequent in the RFA group (27.3%, n = 12 vs. 10.6%, n = 5, p = 0.03).

CONCLUSION: Both RFA and surgical sympathectomy effectively reduce sweating severity in patients with palmar hyperhidrosis. While sympathectomy provides longer-lasting symptom relief and greater QoL improvement, it is associated with a higher incidence of compensatory sweating.

20-Year Efficacy of Endoscopic Thoracic Sympathectomy for Primary Hyperhidrosis: A Cohort Study

J Clin Med. 2025 Jul 8;14(14):4831. doi: 10.3390/jcm14144831.

ABSTRACT

Background: Primary focal hyperhidrosis, characterized by excessive sweating primarily affecting the hands and axillae, can significantly impact quality of life. Bilateral thoracic sympathectomy is the gold standard treatment, providing permanent resolution of palmar hyperhidrosis. Most studies evaluating outcomes and patient satisfaction after sympathectomy focus on short- to medium-term follow-up, typically up to 5 years. This study aimed to assess anxiety, satisfaction, and sweat redistribution 20 years after bilateral endoscopic thoracic sympathectomy. Methods: Between January 2002 and December 2003, 106 patients with primary hyperhidrosis underwent bilateral endoscopic thoracic sympathectomy targeting ganglia T2-T3 at our center. The patients were contacted via telephone in 2023 and asked to complete the same survey they had filled out preoperatively and 12 months postoperatively. The survey evaluated sweat redistribution, anxiety, hyperhidrosis-related symptoms, and satisfaction. Anxiety, satisfaction, and perceived sweating were rated using a 5-point visual analog scale (VAS) ranging from 0 (unsatisfied/no symptoms) to 4 (very satisfied/severe symptoms). Results: Of the 106 eligible patients, 24 (22.6%) completed the survey. Most reported persistent anhidrosis (palmar or palmar-axillary) 20 years post-surgery. The survey results remained consistent with those at the 1-year follow-up. Significant sweat redistribution to the abdomen and back was observed. Patient satisfaction remained high, with no significant differences between the 1-year and 20-year assessments. Anxiety significantly decreased compared to preoperative levels (p < 0.001). Conclusions: Bilateral endoscopic thoracic sympathectomy is an effective long-term treatment for reducing excessive sweating. Patient satisfaction remains high over time, despite the persistence of compensatory sweating.

Primary hyperhidrosis: an updated review

Drugs Context. 2025 Jun 16;14:2025-3-2. doi: 10.7573/dic.2025-3-2. eCollection 2025.

ABSTRACT

BACKGROUND: Hyperhidrosis (HH) is a condition characterized by excessive sweating beyond the physiological needs of thermoregulation. HH can be classified as primary (idiopathic) hyperhidrosis (PHH) or secondary hyperhidrosis (SHH), which is associated with underlying medical conditions, medications or systemic disorders. This narrative review provides an updated overview of PHH, with a focus on epidemiology, aetiopathogenesis, clinical manifestations, diagnostic approaches and current management strategies, particularly highlighting pharmacological and procedural treatment options.

METHODS: A literature search was conducted in February 2025 across Ovid Medline, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL) using the key term “hyperhidrosis”. The review included observational studies, clinical trials, narrative reviews, guidelines and meta-analyses published in the past 10 years. Additional references were identified through manual searches of relevant bibliographies.

RESULTS: The global prevalence of PHH is estimated to range between 0.072% and 9%, with PHH accounting for 93% of all HH cases. Whilst the precise pathophysiology remains unclear, PHH is believed to result from sympathetic overactivity, whereas SHH is associated with endocrine, neurological, infectious, malignant and medication-induced causes. PHH is diagnosed clinically and distinguishing between primary and secondary forms is essential. Management options vary based on severity, ranging from topical therapies (antiperspirants, anticholinergics), systemic medications (oral anticholinergics, adrenergic modulators), device-based interventions (iontophoresis, microwave thermolysis), injectable therapies (botulinum toxin) and surgical approaches (sympathectomy, excision, liposuction/curettage). Whilst these interventions can significantly improve symptoms and quality of life, long-term efficacy, recurrence and adverse effects remain concerns.

CONCLUSION: PHH significantly impacts the quality life of patients contributing to both physical discomfort and psychosocial distress. An individualized, multi-modal approach is crucial to optimizing management. Further research is warranted to refine existing therapies and evaluate emerging treatment modalities for improved long-term outcomes.

T3 Endoscopic Thoracic Ganglionectomy Using Cutting Mode Cautery for Palmar Hyperhidrosis

Ann Thorac Surg Short Rep. 2024 Dec 13;3(2):456-460. doi: 10.1016/j.atssr.2024.12.004. eCollection 2025 Jun.

ABSTRACT

BACKGROUND: Understanding the precise anatomy of the upper thoracic sympathetic trunk is crucial for effectively treating palmar hyperhidrosis using the surgical technique of endoscopic thoracic sympathectomy (ETS). The variability in the location of T2 and T3 ganglia in relation to the ribs may contribute to inconsistent clinical outcomes after ETS.

METHODS: For the cadaver study, adult human cadaveric thoraces were dissected to map the locations of T2 and T3 ganglia by identifying their white rami communicantes. For the ETS group, T3 ganglionectomy ETS was performed. Surgical outcome and postoperative incidence of compensatory sweating were assessed.

RESULTS: A total of 74 pediatric patients underwent thoracoscopic T3 ganglionectomy. All patients were satisfied with the surgical outcomes. No patients complained of compensatory sweating. Forty cadavers were dissected: 25 adult female and 15 adult male. The findings showed that a high percentage of T2 ganglia are near the superior border of the third rib, while the T3 ganglion is near the fourth rib.

CONCLUSIONS: Because of the proximity of the T2 ganglion to the third rib, accidental thermal injury to the T2 ganglion may occur when third rib-oriented ETS is performed. A ganglion-oriented T3 ETS can be accomplished by using the white ramus communicans as a guide to accurately locate the T3 ganglion.
