Single-center experience of thoracoscopic sympathectomy for palmar hyperhidrosis with long-term postoperative questionnaire survey

Gen Thorac Cardiovasc Surg. 2024 Apr 27. doi: 10.1007/s11748-024-02034-w. Online ahead of print.

ABSTRACT

OBJECTIVES: Thoracoscopic sympathectomy is an effective treatment for palmar hyperhidrosis. However, compensatory hyperhidrosis occurs frequently as a postoperative complication of the procedure. The goal of this study was to elucidate the clinical significance of thoracoscopic sympathectomy using our surgical procedure.

METHODS: Consecutive 151 patients who underwent thoracoscopic sympathectomy for palmar hyperhidrosis were studied. In addition, to investigate patients’ satisfaction and long-term quality of life, 111 patients were asked to complete a mailing questionnaire survey, and 84 responded (response rate of 75.7%).

RESULTS: All of the 151 patients reported a reduction in palmar sweating during the immediate postoperative period. None of the patients had pneumothorax, hemothorax, Horner’s syndrome, or worsening of bradycardia. Based on the questionnaire, the surgical success rate was 98.8%. None of the patients had a recurrence of palmar hyperhidrosis during the long-term postoperative period. However, compensatory hyperhidrosis was reported in 82 patients (97.6%). In total, 94.0% of patients had high levels of postoperative satisfaction.

CONCLUSIONS: Thoracoscopic sympathectomy is an effective surgical treatment for palmar hyperhidrosis. By contrast, the careful preoperative explanation of compensatory hyperhidrosis is considered to be very important.

Fifteen Years’ Experience of Thoracoscopic Sympathetic Chain Interruption for Palmar Hyperhidrosis in Children and Adolescents: Evaluation of Different Techniques

J Laparoendosc Adv Surg Tech A. 2024 Apr 5. doi: 10.1089/lap.2024.0026. Online ahead of print.

ABSTRACT

Background: Thoracoscopic sympathetic chain interruption is a definitive and effective therapy for severe primary palmar hyperhidrosis (PPH). Well-known methods include sympathectomy, sympathotomy, and clipping, but the occurrence of compensatory sweating offsets these methods. This study aims to report our experience with thoracoscopic sympathetic chain interruption in a large group of patients of age <18 years with PPH, focusing on surgical outcomes, complication rates, and patient satisfaction. Patients and Methods: This retrospective study included patients who underwent thoracoscopic sympathectomy, sympathotomy, or clipping for severe PPH between April 2008 and March 2023 at the Pediatric Surgery Department, Al-Azhar University Hospitals. Demographic and clinical data, operative steps, postoperative outcomes, complications, and patient satisfaction were reviewed from the patients’ medical records. Results: During the 15-year study period, 420 children with PPH underwent bilateral thoracoscopic sympathetic chain interruption by either sympathectomy, sympathotomy, or clipping, with a sex ratio of 60% being females. The mean ages were 12 ± 3.48, 13 ± 2.45, and 13 ± 2.45 years, respectively. Sympathectomy was performed in 190 patients (45.2%), sympathotomy in 170 patients (40.5%), and clipping in 60 patients (14.3%). All patients had completed follow-up, with mean periods of ∼43 ± 5 months, 45 ± 3 months, and 42 ± 6 months, respectively. Complete palmar dryness was achieved in 405 patients (overall 96.4%) (97.8% after sympathectomy, 97.05% after sympathotomy, and 90% after clipping), whereas 2.1%, 2.9%, and 10% of patients experienced symptom recurrence, respectively, denoting significant statistical differences. Overall, 94 patients (22.4%) experienced compensatory sweating. Eventually, 409 patients (97.4%) were satisfied with the outcome, whereas 11 patients (2.6%) reported dissatisfaction, yet no significant differences found. Conclusion: The presented three modalities of thoracoscopic sympathetic chain interruption for PPH in children and adolescents are safe and effective, with overall very high postoperative satisfaction, despite a relatively high rate of compensatory sweating in sympathectomy group. Other major complications in this age population were scanty.

Efficacy and safety of radiofrequency ablation versus surgical sympathectomy in palmar hyperhidrosis

Sci Rep. 2024 Apr 1;14(1):7620. doi: 10.1038/s41598-024-57834-0.

ABSTRACT

Radiofrequency ablation (RFA) comparative efficacy of treatments using video-assisted thoracoscopic sympathectomy (VATS) in the long term remains uncertain in patients with palmar hyperhidrosis (PHH). This study aimed to compare the efficacy and safety of RFA and VATS in patients with PHH. We recruited patients aged ≥ 14 years with diagnosed PHH from 14 centres in China. The treatment options of RFA or VATS were assigned to two cohort in patients with PHH. The primary outcome was the efficacy at 1-year. A total of 807 patients were enrolled. After propensity score matching, the rate of complete remission was lower in RFA group than VATS group (95% CI 0.21-0.57; p < 0.001). However, the rates of palmar dryness (95% CI 0.38-0.92; p = 0.020), postoperative pain (95% CI 0.13-0.33; p < 0.001), and surgery-related complications (95% CI 0.19-0.85; p = 0.020) were lower in RFA group than in VATS group, but skin temperature rise was more common in RFA group (95% CI 1.84-3.58; p < 0.001). RFA had a lower success rate than VATS for the complete remission of PHH. However, the symptom burden and cost are lower in patients undergoing RFA compared to those undergoing VATS.Trial Registration: ChiCTR2000039576, URL: http://www.chictr.org.cn/index.aspx .

Enhancing Quality of Life: Pre- and Postoperative Assessment in Idiopathic Hyperhidrosis Patients

Cureus. 2023 Nov 28;15(11):e49588. doi: 10.7759/cureus.49588. eCollection 2023 Nov.

ABSTRACT

OBJECTIVE: This study aimed to characterize patients, describe surgical complications, and evaluate the pre- and postoperative quality of life (QOL) of individuals who underwent surgery for primary hyperhidrosis (PHH).

METHODS: A prospective, non-randomized, uncontrolled study was conducted, documenting cases of patients undergoing surgery for PHH at a reference center in La Habana, Cuba, from January 2016 to December 2022.

RESULTS: A total of 49 cases were described, with a median age of 16 years; 59.1% were female. The most common presentation was palmar-plantar-axillary, observed in 53% of cases. The palmar presentation was more frequent in female patients (p<0.05). Within 24 hours post-procedure, 85.7% of patients showed dryness in the palmar and axillary areas, with surgical complications occurring in 14.3% of cases (intercostal neuritis, pneumothorax, and hemothorax). CH of some form was recorded in 89.8% of cases. At least 30 days after the surgery, 95.9% of the patients reported a significant improvement in their QOL.

CONCLUSION: Thoracic sympathectomy is an efficient and safe method for treating hyperhidrosis in adolescents, leading to an enhanced QOL. However, this study reported a higher incidence of complications, particularly CH, compared to previous national and international studies.

A multicenter retrospective study of lumbar sympathectomy for plantar hyperhidrosis: satisfaction and postoperative complications

Clin Exp Dermatol. 2023 Nov 15:llad373. doi: 10.1093/ced/llad373. Online ahead of print.

ABSTRACT

Primary plantar hyperhidrosis has a severe impact on quality of life and conservative treatments are only effective in the short-term. Thoracic sympathectomy has proven its effectiveness in the treatment of palmar hyperhidrosis, but lumbar sympathectomy for plantar hyperhidrosis remains poorly described. The objective of this study is to report the satisfaction of treated patients as well as the postoperative complications. This was a multicenter retrospective observational study of sixteen patients with primary plantar hyperhidrosis, treated with mechanical lumbar sympathectomy from December 2012 to October 2022. Patients’ characteristics were collected from medical records. Quality of life, postoperative satisfaction and complications were evaluated using a standardized questionnaire. Lumbar sympathectomy was performed on 16 patients, fourteen were women and two were men with a total of thirty-one procedures. 87.5% of patients were satisfied and would recommend the surgery to other patients. Compensatory hyperhidrosis occured in 75% of patients, recurrence of hyperhidrosis in 31.3% and sexual dysfunction in 18.8%. Lumbar sympathectomy provides satisfying results for plantar hyperhidrosis with acceptable postoperative complications, regardless of gender. Compensatory hyperhidrosis was the most frequent complication but had no impact on patient satisfaction. Data on the risk of sexual dysfunction are reassuring, with only one case of transient ejaculation disorder.

Ultrasound-guided percutaneous puncturing technique: novel radiofrequency ablation technique for thoracic sympathectomy in treatment of palmar hyperhidrosis

Eur J Cardiothorac Surg. 2023 Nov 8:ezad372. doi: 10.1093/ejcts/ezad372. Online ahead of print.

ABSTRACT

Radiofrequency thoracic sympathectomy is routinely conducted under computed tomography or fluoroscopy in treatment of palmar hyperhidrosis. However, it remains a great challenge to perform thoracic paravertebral puncture precisely and safely, that is associated with repeated exposure of radiation and risk of pneumothorax. Alternatively, ultrasound-guided technique can provide high-resolution and real-time needle tracking during percutaneous procedure. Here, we provided our experience of ultrasonic guidance in radiofrequency sympathectomy for treatment of primary palmar hyperhidrosis.

The success rate and associated risk factors of CT-guided percutaneous radiofrequency sympathectomy in the treatment of primary hyperhidrosis: A retrospective observational trial

J Clin Neurosci. 2023 Oct 25;118:81-89. doi: 10.1016/j.jocn.2023.10.010. Online ahead of print.

ABSTRACT

PURPOSE: The aim of this study was to investigate the success rate of surgical technique and associated risk factors based on the follow-up of patients who underwent CT-guided percutaneous radiofrequency sympathectomy (RFS) to treat primary hyperhidrosis (PH).

METHODS: 370 patients who underwent RFS for PH treatment between January 2018 and April 2022 were enrolled. Patients responded to a questionnaire and telephone follow-up on the effects of treatment and their electronic medical records and imaging findings were reviewed. Logistic regression was performed to identify risk factors related to the success rate of surgical technique.

RESULTS: A temperature difference ≥2 °C before and after procedure was defined as a successful surgical technique. Among the 370 patients (740 sides), 637 sides had successful RFS, and the technical success rate was 86.1 %. Immediately after procedure, 636 sides (85.9 %) were completely dry, 64 (8.7 %) were partially dry, and 40 (5.4 %) were still wet. During the longest follow-up period (54 months), 103 patients relapsed. The median hyperhidrosis disease severity scale score on both sides decreased from 4 to 1 after RFS. According to logistic regression analysis, only the pre-post pulse index was associated with the success rate of surgical technique (odds ratio, 1.14; 95 % confidence interval, 1.06-1.23; p = 0.0004).

CONCLUSIONS: We observed that the immediate efficiency and success rate of surgical technique after RFS for PH treatment were relatively high, although there is a possibility of recurrence in the long term. In general, RFS is a safe and effective procedure for alleviating the symptoms of patients with hyperhidrosis.

Machine learning analysis of primary hyperhidrosis for classification of hyperhidrosis type and prediction of compensatory hyperhidrosis

J Thorac Dis. 2023 Sep 28;15(9):4808-4817. doi: 10.21037/jtd-23-471. Epub 2023 Aug 23.

ABSTRACT

BACKGROUND: Although sympathectomy is highly effective for improving symptom, compensatory hyperhidrosis (CH) is a major issue. In this study, characteristics of primary hyperhidrosis were investigated in terms of the heart rate variability (HRV) parameters. Classification of hyperhidrosis type and prediction of CH after sympathicotomy were also determined using machine learning analysis.

METHODS: From March 2017 to December 2021, 128 subjects who underwent HRV tests before sympathicotomy were analyzed. T2 and T3 bilateral endoscopic sympathicotomy were routinely performed in patients with craniofacial and palmar hyperhidrosis, respectively. Data collected age, sex, body mass index (BMI), hyperhidrosis type, symptom improvement after sympathicotomy, the degrees of CH after sympathicotomy, and preoperative HRV findings. The independent risk factors associated with the degree of CH after sympathicotomy were investigated. Machine learning analysis was used to determine classification of hyperhidrosis type and prediction of the degree of CH.

RESULTS: Preoperatively, patients with palmar hyperhidrosis presented with significantly larger standard deviation of normal-to-normal (SDNN), root mean square of successive differences (RMSSD), total power (TP), and low frequency (LF) than patients with craniofacial hyperhidrosis after controlling for age and sex (P=0.030, P=0.004, P=0.041, and P=0.022, respectively). More sympathetic nervous predominance was found in craniofacial type (P=0.019). Low degree of CH had significantly greater RMSSD (P=0.047), and high degree of CH showed more sympathetic nervous predominance (P=0.006). Multivariate analysis showed the type and expansion of sympathicotomy were significant factors for CH (P=0.001 and P=0.028, respectively). The neural network (NN) algorithm outperformed and showed a 0.961 accuracy, 0.961 F1 score, 0.961 precision, 0.961 recall, and 0.972 area under the curve (AUC) for classification of hyperhidrosis type. The random forest (RF) model outperformed showed a 0.852 accuracy, 0.853 F1 score, 0.856 precision, 0.852 recall, and 0.914 AUC for prediction of the degree of CH.

CONCLUSIONS: The present study showed the machine learning algorithm can classify types and predict CH after sympathicotomy for primary hyperhidrosis with considerable accuracy. Further large-scale studies are needed to validate the findings and provide management guidelines for primary hyperhidrosis.

Development and Validation of a Nomogram to Predict Recurrence of Primary Hyperhidrosis after CT-guided Percutaneous Radiofrequency Sympathectomy

J Vasc Interv Radiol. 2023 Aug 5:S1051-0443(23)00568-7. doi: 10.1016/j.jvir.2023.07.030. Online ahead of print.

ABSTRACT

PURPOSE: To evaluate the recurrence rate of primary hyperhidrosis (PH) after computed tomography (CT)-guided radiofrequency sympathectomy (RFS) and to identify risk factors associated with recurrence.

MATERIALS AND METHODS: A total of 290 patients with PH who received CT-guided RFS were included in this retrospective cohort study. The electronic medical record was queried for patients’ information and surgical parameters. Follow-ups were conducted for recurrence rate, and Hyperhidrosis Disease Severity Scale was used to assess presence or absence of recurrence. Stepwise regression and the least absolute shrinkage and selection operator regression algorithms were used for feature selection.

RESULTS: The recurrence rate 1 year after procedure was 17.6%. Male (hazard ratio [HR]: 2.35, 95% confidence interval [CI]:1.08-5.15), low postoperative palm or foot temperature (HR: 0.77, 95% CI:0.60-0.98), high postoperative heart rate (HR: 1.06, 95% CI:1.02-1.10), low preoperative and postoperative hospital anxiety and depression score difference (HR: 0.59, 95% CI:0.43-0.80), and the absence of compensatory hyperhidrosis immediately after procedure (HR: 0.46, 95% CI:0.22-0.98) were established as independent factors affecting prognosis. A nomogram was built accordingly. The C-indices of the training and testing sets were 0.773 and 0.659, respectively.

CONCLUSION: Follow-up results showed that the recurrence rate of PH treated with CT-guided RFS was low. This study constructed and validated a nomogram to predict the recurrence of PH 1 year after CT-guided RFS, which is convenient for interventionalists to accurately evaluate the prognosis of postoperative patients, identify high-risk patients who need more active treatment.
