Single-port Thoracoscopic Laser Sympathicotomy for Primary Hyperhidrosis: A Safe and Minimally Invasive Approach With Favorable Short-term Outcomes.

Thoracoscopic sympathicotomy is a well-established treatment for severe palmar hyperhidrosis. This study evaluates the safety and efficacy of a novel one-stage, bilateral, single-port laser sympathicotomy with minimal dissection. We retrospectively reviewed 73 patients with severe palmar hyperhidrosis who underwent this novel surgical technique between June 2023 and October 2023. Outcomes included complications, recurrent hyperhidrosis, and compensatory hyperhidrosis (CH). Hyperhidrosis severity was assessed using the hyperhidrosis disease severity score (HDSS). The mean patient age was 21.3 ± 7.7 years, with a female predominance (52.1%). Sympathicotomy was performed at the T3 level only in 46 patients (63%), with the remaining undergoing sympathicotomy at both T3 and T4 levels. Median cauterization and operating times were 78 seconds and 8.7 minutes, respectively. No complications occurred. Two patients experienced recurrent hyperhidrosis during a median follow-up of 9 months, both were mild (HDSS grade 1). CH developed in 41 patients (56.2%), with all occurring within the first month postoperatively. The most common sites for CH were the back (51.2%), chest (43.9%), thigh (41.5%), abdomen (36.6%), and lower leg (36.6%). The majority of patients with CH (95.1%) reported mild (HDSS grade 1) or moderate (HDSS grade 2) hyperhidrosis. A higher body mass index was a significant risk factor for CH (odds ratio: 1.36, 95% CI: 1.12-1.71 for every 1kg/m2 increase). This minimally invasive, single-port thoracoscopic laser sympathicotomy appears to be safe and effective for patients with palmar primary hyperhidrosis. Future studies should investigate long-term outcomes and refine the technique to minimize invasiveness even further.

Long term outcomes and risk factors of compensatory hyperhidrosis after thoracoscopic sympathectomy in primary palmar hyperhidrosis patients: a retrospective single-center study

ObjectiveThis study aims to evaluate the long-term outcomes of compensatory hyperhidrosis (CH) after thoracoscopic sympathectomy and explore the risk factors affecting postoperative CH in primary palmar hyperhidrosis(PPH) patients.MethodA retrospective analysis was conducted on patients who underwent thoracoscopic sympathectomy in the thoracic surgery department of our hospital from January 2015 to May 2022. Long-term follow-up surveys was conducted to collect data on post-operative satisfaction, PPH recurrence, and CH occurrence. Postoperative CH outcomes were assessed using the HDSS and satisfaction scores scale. Univariate and multivariate logistic regression analyses were used to identify independent risk factors for postoperative CH.ResultA total of 152 patients was included in the final study, with 113 cases in the CH group and 39 cases in the nCH group. The incidence of postoperative CH was 74.3% (113/152), within which 33.6% (38/113) were severe CH. The median follow-up time was 3.1 years(2.5-5.5y) and the median interval of CH onset after surgery was 30 days (14-90d). Univariate analysis showed that body mass index(BMI), surgical time, and transected nerve level are correlated with CH, with statistically significant differences. Multivariate logistic regression analysis indicated a higher BMI (OR = 0.864, 95% CI 0.755–0.989, P < 0.05) is the independent risk factor for the occurrence of CH. There was no statistically significant difference in HDSS scores among CH patients at 1 month, 1 year, and 3 years after surgery.ConclusionA higher BMI is the independent risk factor for postoperative CH after thoracoscopic sympathectomy. The incidence and severity of postoperative CH kept stable during a long term follow up.

Incidence and Severity of Compensatory Hyperhidrosis Following Bilateral Sympathectomy

Primary hyperhidrosis is a condition caused by an excessive stimulation of sweat glands, leading to a decline in both quality of life and social wellbeing. Thoracic sympathectomy surgery provides a relief of the initial symptoms but poses a risk for developing compensatory hyperhidrosis (CH) in various degrees. The aim of this study was to assess the occurrence and characteristics of CH post-thoracic sympathectomy. A retrospective cohort study of patients who underwent video-assisted thoracic sympathectomy surgery at level T2-T3 between 2016 and 2022 was conducted. Patients' data were retrieved from medical records and through a telephone interview. A total of 50 patients (32 males and 18 females) were operated on with a mean±standard deviation (SD) age of 25.9±7.4years at the time of surgery for palmoplantar hyperhidrosis. Initial symptoms started in childhood at a mean±SD age of 11.4±3.3years. Postoperatively, 39 patients (78%) developed CH, more prevalent in males (64.1%) compared to females (35.8%). This CH mainly affected the back and abdomen (100%), followed by the groin and thighs (28.2%), and, to a lesser extent, the craniofacial area (15.3%). Onset of symptoms occurred within 1week after surgery in 71.7% of cases, with 71.7% reporting mild to moderate symptoms. CH was significantly associated with higher age at the time of surgery, smoking status, and a longer time lapse in the surgery operation (P value<0.05). Thoracic sympathectomy is an effective procedure with a high success rate. Despite a relatively higher occurrence of CH, most patients experience milder symptoms and express satisfaction, noting that their expectations were met following the surgery.

Robotic thoracic surgery for neurogenic tumors.

Thoracic neurogenic tumors usually present as benign nerve sheath tumors that can be resected via transthoracic or posterior approaches, depending on the anatomical location. Robot-assisted thoracic surgery (RATS) is increasingly being used for the transthoracic approach, but evidence is very limited. The authors initiated the current study to evaluate the efficacy and safety of RATS for thoracic neurogenic tumors. This retrospective study is based on a prospectively created database that includes all RATS surgeries between 2018 and 2023. All patients with histologically confirmed neurogenic tumors were included in the study. The patients' medical and surgical records as well as radiological and pathological findings were analyzed. During a 5-year period, 27 patients underwent robotic resection of neurogenic tumors at a high-volume thoracic surgery center. Two patients had previously undergone posterior laminectomy for resection of the intraspinal components. The pathologies included schwannomas (18, 64%), ganglioneuromas (8, 29%), 1 paraganglioma, and 1 neurofibroma occurring close to a schwannoma unilaterally in the same patient. The median tumor size was 4.7 cm (range 0.9-11.4 cm). The median operating time was 69 minutes (range 27-169 minutes), and the median postoperative stay was 3 days (range 1-19 days). There was one conversion due to adhesions after a previous surgery. No major bleeding occurred. There was no perioperative mortality. Morbidity included a lymphatic fistula (n = 1), pneumonia (n = 1), prolonged air leak (n = 1), and 4 cases of postoperative pain persisting for more than 4 weeks. Neurological complications were mostly observed in patients with tumors located at the thoracic apex: 2 cases of Horner's syndrome, 2 cases with compensatory hyperhidrosis, 1 patient with paresis of the recurrent laryngeal nerve, and a T1 lesion resulting in a minor motor deficit of the small hand muscles (Medical Research Council grade 4) and hypoesthesia of the respective dermatome. RATS for thoracic neurogenic tumors is feasible and safe. Tumors at the thoracic apex are at high risk of neurological deficit and should be approached with care. Close interdisciplinary collaboration between neurosurgeons and thoracic surgeons is necessary for optimal patient selection and a good postoperative outcome.

Sympathectomy in the treatment of hyperhidrosis: Is it an effective solution?

Background: Primary hyperhidrosis affects 1-3% of the general population and occurs equally in both genders. It significantly affects the quality of life. In recent years, endoscopic thoracic sympathectomy (ETS), especially with a single-port approach, has gained popularity in the treatment of primary hyperhidrosis. This study aims to assess the efficacy and clinical outcomes of ETS surgery for primary hyperhidrosis. Materials and Methods: The data of 30 patients who underwent bilateral ETS due to primary hyperhidrosis were examined retrospectively. 25 patients treated with a single port approach were included in the study, and 5 patients treated with a double port approach were excluded from the study. Preoperative evaluations and routine tests were performed. Patients were evaluated in terms of age, gender, complications, satisfaction, compensatory sweating, and relapse. Patients' satisfaction levels were determined by telephone interviews. Results: The mean patient age was 24.16 ± 6.01 years; 56% were men and 44% were women. As complications, compensatory hyperhidrosis was observed in 12% of the patients, and mild pneumothorax was observed in 12%. No operative mortality occurred. No recurrence was observed during the long-term follow-up. In telephone surveys, 88% of patients reported satisfaction. Three patients with compensatory sweating were partially satisfied. No patient reported regret. Conclusions: We believe that ETS is an effective option in the treatment of primary hyperhidrosis, with low morbidity and high patient satisfaction rates, despite the risk of compensatory sweating.

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

ObjectivesThoracoscopic 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.MethodsConsecutive 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%).ResultsAll 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.ConclusionsThoracoscopic sympathectomy is an effective surgical treatment for palmar hyperhidrosis. By contrast, the careful preoperative explanation of compensatory hyperhidrosis is considered to be very important.

The Role of Sympathetic Nerve Block in Predicting Compensatory Hyperhidrosis before Thoracoscopic Sympathectomy

The Role of Sympathetic Nerve Block in Predicting Compensatory Hyperhidrosis before Thoracoscopic Sympathectomy

Single port endoscopic thoracic sympathectomy with holmium laser for treating palmar hyperhidrosis at Thai Binh Provincial General Hospital

Introduction: thoracoscopic sympathectomy for treating palmar hyperhidrosis often uses 2 ports. Research to evaluate the results of the method using 1 port &lt; 5mm with Holmium Laser fiber.&#x0D; Object and Method: Description, prospective.&#x0D; Within 2 months from June 2023 to July 2023, 47 patients underwent single port endoscopic thoracic surgery using holmium laser to transect the sympathetic ganglia at T3 level for patients with palm sweating (26 patients) and T3-T4 level for patients with palm and axillary sweating (21 patients). The male-to-female ratio was 44.7% to 55.3%, with an average age of 18 ± 7.4 years (minimum age of 11 years, maximum age of 52 years). Surgical method: A single entry port trocar 14Fr located at the 3rd intercostal space, the posterior border of the pectoralis major muscle between the anterior and midaxillary lines, using a 12Fr endoscopic lens with integrated tunnel for Holmium Laser fiber. Patients were monitored and evaluated for early post-operative results: technical failure requiring the placement of a second port, complications during and after surgery and the degree of improvement in palmar hyperhidrosis, the rate of compensatory hyperhidrosis after 1 month and the patient's quality of life after surgery.&#x0D; Results:&#x0D; There were no technical failures. The time for transecting the sympathetic ganglion (one side) with Holmium Laser was 78 ± 40.76 seconds. All patients had dry hands after surgery, with two out of forty-seven patients having excessively dry hands. There were no complications during or after surgery, and no patients developed Horner’s syndrome. The average time to discharge after surgery was 30 ± 11.4 hours. Fourteen out of forty-seven patients had compensatory sweating after one month postoperatively at an acceptable level.&#x0D; Conclusion: The method of using a port &lt; 5mm with an endoscopic lens integrated with a Holmium Laser fiber tunnel is safe, effective, less traumatic and highly aesthetic.

The Impact of bilateral endoscopic thoracic sympathectomy on hyperhidrosis patients’ quality of life and its link to psychiatric disorders

Background and Aims: To measure the Quality of Life (QOL) of patients with hyperhidrosis after undergoing Bilateral en¬doscopic thoracic sympathectomy (BETS), and its association with psychiatric disorders, that were diagnosed using MINI psychiatric interview, and compensatory hyperhidrosis (CH). Methods: A retrospective cross-sectional study was carried out on patients with primary hyperhidrosis after undergoing BETS. 50 Patients were recruited from King Saud University Medical City database and contacted via phone calls. The interview contained a hyperhidrosis-specific QOL questionnaire, and a diagnostic psychiatric questionnaire MINI. The QOL results were classified into 5 categories and used to study QOL and its associated factors. Results: The reported QOL before the operation has 52% of the patients showing negative QOL. Alternately, the reported QOL after the operation improved with 96% patients showing positive QOL. Among this sample, 76% reported suffering from CH post procedure, 28% were diagnosed with one or more mood disorders, and 20% were diagnosed with one or more anxiety disorders. No statistical relationship was found linking the QOL of the sample to the occurrence of CH or the presence of any common psychiatric disorder. Conclusions: In conclusion, there was a significant improvement in the patients’ QOL after BETS. The improvement in QOL was unaffected by the surgeries most notable complication, compensatory hyperhidro¬sis, or the presence of any common psychiatric disorder that they were diagnosed with post-surgery. Further research is needed to explore factors that may affect the QOL of these patients.

Case-Series: First experience outcome of t2 - t4 video-assisted thoracoscopic surgery (vats) sympathectomy bilateral for severe hyperhidrosis in Labuang Baji general hospital

Introduction: Hyperhidrosis is a clinical condition that causes excessive sweating that exceeds physiological needs and can interfere with the patient's daily activities Methods: This research is a retrospective study based on medical record data from March 2022 – March 2023 at Labuang Baji Hospital. Six cases of severe hyperhidrosis who underwent a bilateral T2-T4 VATS sympathectomy procedure were subsequently conducted through cell phone interviews to assess complications of the procedure, the incidence of Compensatory Hyperhidrosis, length of stay in hospital and assess patient satisfaction after 1 year of undergoing the procedure. Result: Four of the patients experienced improvement and were very satisfied with undergoing the VATS sympathectomy procedure, one patient was quite satisfied and the other was dissatisfied because the complaint of compensatory hyperhidrosis (CH) experienced was more disturbing to the patient's activities than before surgery. Complications found besides pain are subcutis emphysema, pleural effusion and bleeding. All patients experienced CH, which predominated in the chest and back areas. Conclusion: Bilateral VATS sympathectomy in cases of severe hyperhidrosis is a minimally invasive procedure that can be recommended for the future. This action gives results, a good level of satisfaction and can improve patients' quality of life after surgery.

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

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. 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. 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. 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

PurposeTo evaluate the recurrence rate of primary hyperhidrosis (PH) after computed tomography (CT)-guided radiofrequency sympathectomy (RFS) and identify risk factors associated with recurrence. Materials and MethodsA total of 290 patients with PH who underwent CT-guided RFS were included in this retrospective cohort study. The electronic medical record was reviewed for patients’ information and procedural 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. ResultsThe 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. ConclusionsFollow-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 evaluate accurately the prognosis of patients postoperatively and to identify high-risk patients who need more active treatment.

Compensatory Hyperhidrosis After Non-Surgical Treatment of Primary Focal Hyperhidrosis: Two-Year Single-Centered Prospective Study From Jordan.

Primary focal hyperhidrosis (PH) can be managed by a wide range of medical and surgical modalities. Compensatory hyperhidrosis (CH) is a well-documented complication of surgical treatment. We aimed to investigate the occurrence of compensatory hyperhidrosis (CH) in PH patients after nonsurgical treatment with botulinum toxin A (BTX- A) or iontophoresis. We carried out a unicentric prospective study on PH patients from King Abdullah University Hospital (KAUH) in Jordan. PH patients were evaluated after 1-month of nonsurgical treatment. Patients who developed CH were re-assessed after 3-6 months through a telephone-based interview. A total of 86 patients with PH who underwent nonsurgical treatment with iontophoresis or botulinum toxin were recruited. Twenty-four (27.9%) patients developed subjective CH. It was mild in (75%), moderate in (21%), and severe in (4%) of patients affected, it was self-limiting within a few months in all patients. Patients with CH did not differ significantly in demographic or clinical variables from patients who did not develop CH except at the site of PH (p value = .05). The findings of this study indicate that more than quarter (27.9%) of patients with PH may develop minor compensatory sweating, however this didn't affect satisfaction with treatment.

T3-T5 Thoracoscopic sympathectomy versus sympathicotomy in the treatment of palmar–axillary–plantar hyperhidrosis

Background Compensatory hyperhidrosis is a common complication after thoracoscopic interruption of the sympathetic chain in hyperhidrosis patients. Nonetheless, no interruption technique has been defined to decrease the incidence of that dreadful complication. Herein, we compared T3-5 sympathectomy with sympathicotomy at the same levels with regard to postoperative outcomes. Methods Eighty patients diagnosed with primary palmar–axillary–plantar hyperhidrosis were randomized into two equal groups: the sympathectomy and sympathicotomy groups. They were followed up for 6 months after the procedure. The incidence and criteria of compensatory hyperhidrosis were compared between the two approaches. Results The sympathectomy group showed a significant prolongation of the operative time. However, postoperative pain, hospital stay, and the incidence of complications were statistically comparable between the two approaches. Both procedures were associated with a significant decline in the severity of sweating in the three regions, which was more prominent in the palmar and axillary regions compared with the foot. The incidence of compensatory hyperhidrosis was 65% in sympathectomy patients and 77.5% in sympathicotomy patients, with no significant difference between them (P=0.217). About two-thirds of these cases were temporary, and the majority of them had mild to moderate symptoms. Patient satisfaction did not differ between the two approaches, with poor satisfaction in patients with permanent compensatory hyperhidrosis. Conclusion Both sympathectomy and sympathicotomy had comparable outcomes in patients with palmar–axillary–plantar hyperhidrosis, manifested in comparable decreased sweating severity, incidence of compensatory hyperhidrosis, quality of life, and patient satisfaction.

Impact of robotic-assisted and video-assisted sympathetic nerve reconstruction on quality of life for severe compensatory hyperhidrosis after thoracic sympathectomy.

Severe compensatory hyperhidrosis (CH) is a disabling complication following thoracic sympathectomy. Our study was to establish valid patient selection criteria and determine outcomes of nerve reconstructive surgery. Furthermore, we assessed the clinical feasibility and safety of a robotic-assisted approach compared to video-assisted thoracoscopic surgery. Adults with severe CH following bilateral sympathectomy for primary hyperhidrosis were enrolled. We performed 2 questionnaires: the Hyperhidrosis Disease Severity Scale and the Dermatology Life Quality Index before and 6 months after nerve reconstructive surgery. A one-time evaluation of healthy volunteers (controls) was undertaken to validate the quality of life measures. Fourteen patients (mean age 34.1 ± 11.5 years) underwent sympathetic nerve reconstruction. None of the patients had a recurrence of primary hyperhidrosis. Improvement in quality of life was reported in 50% of patients. Both mean Hyperhidrosis Disease Severity Scale and mean Dermatology Life Quality Index were significantly reduced compared to preoperative assessments. In 10 patients, a video-assisted approach and in 4 patients robotic assistance was utilized. There was no significant difference in outcomes between approaches. Somatic-autonomic nerve reconstructive surgery offers a reversal in the debilitating symptoms in some patients with severe CH. Proper patient selection, preoperative counselling and management of expectation are of paramount importance. Robot-assisted thoracic surgery is an alternative method to conventional video-assisted surgery. Our study provides a practical approach and benchmark for future clinical practice and research.

Anatomical variation of sympathetic ganglia in R4+R5 sympathicotomy for primary palmar axillary hyperhidrosis.

R4+R5 sympathicotomy is one of the standard surgical treatments for primary palmar axillary hyperhidrosis (PAH), but the reported outcomes vary. Anatomical variation of sympathetic ganglia is hypothesized to be a cause for this phenomenon. The sympathetic ganglia could be visualized via near-infrared (NIR) fluorescent thoracoscopy, we utilize this novel technique to observe the anatomical variation of sympathetic ganglia T3 and T4 and investigate its relationship with surgical outcomes. This is a prospective multi-center cohort study. All patients received intravenous indocyanine green (ICG) infusion 24 hours preoperatively. Anatomical variation of sympathetic ganglia T3 and T4 was observed via fluorescent thoracoscopy. Standard R4+R5 sympathicotomy was performed regardless of anatomical variation. Patients were followed up for the therapeutic outcome. One hundred and sixty-two patients in total were enrolled in this study and 134 patients with bilateral clearly visualized thoracic sympathetic ganglia (TSG) were included. The success rate of fluorescent imaging of thoracic sympathetic ganglion was 82.7%. The T3 ganglion was shifted downward on 32 sides (11.9%) and no upward-shifted ganglion was identified. The T4 ganglion was shifted downward on 52 sides (19.4%) and no upward-shifted ganglion was identified. All patients underwent R4+R5 sympathicotomy and no perioperative death or severe complication occurred. The total improvement rates on palmar sweating at short-term and long-term follow-up were 98.1% and 95.1%, respectively. There were significant differences between T3 normal and T3 variation subgroups both in short-term (P=0.049) and long-term (P=0.032) follow-ups. The total improvement rates on axillary sweating at short-term and long-term follow-ups were 97.0% and 89.6%, respectively. No significant difference was found between T4 normal and T4 variation subgroups both in short-term and long-term follow-ups. No significant difference was found between normal and variation subgroups on the degree of compensatory hyperhidrosis (CH). NIR fluorescent thoracoscopy provides clear identification of anatomical variations of sympathetic ganglia during R4+R5 sympathicotomy. The improvement of palmar sweating was significantly affected by anatomical variation of T3 sympathetic ganglia.

Comparison of CT-guided thoracic sympathetic nerve block and radiofrequency in the treatment of primary palmar hyperhidrosis.

Primary palmar hyperhidrosis (PPH) is a condition marked by an overactive secretion of the hand's exocrine glands and is frequently hereditary. The profuse sweating associated with this condition can significantly impair the patient's daily activities and quality of life. The objective of this study was to compared the benefits and drawbacks of thoracic sympathetic block and thoracic sympathetic radiofrequency in the treatment of PPH. A retrospective analysis was conducted on 69 patients. They were divided into groups A and B according to their treatment. Group A (34 cases) received CT-guided percutaneous thoracic sympathetic nerve chain anhydrous alcohol chemical damage block, and group B (35 cases) received CT-guided percutaneous thoracic sympathetic nerve chain radiofrequency thermocoagulation. Palmar sweating disappeared immediately after the operation. The recurrence rates at 1, 3, 6, 12, 24, and 36 months were 5.88% vs. 2.86% (P > 0.05), 20.59% vs. 5.71% (P > 0.05), 32.35% vs. 11.43% (P < 0.05),32.35% vs. 11.43% (P < 0.05), 25% vs. 14.71% (P < 0.05), and 68.75% vs. 20.59% (P < 0.05), respectively. The incidence of intercostal neuralgia and compensatory hyperhidrosis was higher in group A compared with of group B (52.94% vs. 22.86%, P < 0.05; 55.88% vs. 22.86%, P < 0.05). Both methods were found to be effective in treating PPH, but thoracic sympathetic radiofrequency had a longer-term effect, a lower recurrence rate, and a lower incidence of intercostal neuralgia and compensatory hyperhidrosis than a thoracic sympathetic block.

Comparison of the efficacy of ETS with different segments for palmar, axillary and plantar hyperhidrosis

BackgroundTo compare the near and long-term outcomes of endoscopic thoracic sympathectomy (ETS) for palmar, axillary and plantar hyperhidrosis.MethodsWe retrospectively analyzed the clinical data of 218 patients with hyperhidrosis who were admitted to the Department of Thoracic Surgery of Gansu Provincial People’s Hospital for surgical treatment from April 2014 to August 2021. The patients were divided into three groups according to the method of ETS and the perioperative clinical data and postoperative follow-up data were collected to compare the near and long term outcomes of the three groups.ResultsThere were 197 eligible patients at follow-up, 60 patients in the R4 cut-off group, 95 patients in the R3 + R4 cut-off group and 42 patients in the R4 + R5 cut-off group. There were no statistically significant differences in baseline indicators such as sex, age and positive family history among the three groups (P > 0.05). There was no statistically significant difference between the three groups in terms of operative time (P = 0.148), intraoperative bleeding (P = 0.308) and postoperative hospital stay (P = 0.407). Postoperatively, all three groups showed significant relief of palmar hyperhidrosis symptoms, with the R3 + R4 group having an advantage in terms of relief of axillary hyperhidrosis symptoms, patient satisfaction and quality of life index at 6 months postoperatively and the R4 + R5 group having an advantage in terms of relief of plantar hyperhidrosis symptoms. The difference in compensatory hyperhidrosis at 12 months postoperatively was not statistically significant among the three groups (P = 0.867), but the incidence was higher in the R3 + R4 and R4 + R5 groups than that in the R4 group.ConclusionPatients with simple palmar hyperhidrosis can first consider R4 cut-off treatment; R3 + R4 cut-off is more effective in treating palmar hyperhidrosis combined with axillary hyperhidrosis; R4 + R5 cut-off is more effective in treating palmar hyperhidrosis combined with plantar hyperhidrosis. However, patients need to be informed that R3 + R4 and R4 + R5 dissection may increase the risk of severe compensatory hyperhidrosis after surgery.

Anatomical variations of the thoracic sympathetic ganglions and their effects on sympathicotomy for primary palmar hyperhidrosis

PurposeThe results and side effects of sympathicotomy for primary palmar hyperhidrosis (PPH) can vary due to anatomical variations of the sympathetic ganglions. The aim of our study was to clarify anatomical variations of the sympathetic ganglions by near-infrared (NIR) thoracoscopy and determine their effects on sympathicotomy for PPH.Methods The cases of 695 consecutive patients with PPH treated with either R3 or R4 sympathicotomy either by normal thoracoscopy or by NIR fluorescent thoracoscopy between March 2015 and June 2021 were retrospectively reviewed and followed up.ResultsThe variation rate of third and fourth ganglions was 14.7% and 13.3% on the right side and 8.3% and 11.1% on the left side. Real T3 sympathicotomy (RTS3) was more effective than real T4 sympathicotomy (RTS4) in the short-term and long-term follow-up (p < 0.001 and p < 0.001, respectively). RTS3 was more satisfactory than RTS4 in the long-term follow-up (p = 0.03), but no significant difference was found in the short-term follow-up (p = 0.24). The incidence and severity of compensatory hyperhidrosis (CH) in the areas of the chest and back in the RTS4 group were significantly lower than those in the RTS3 group according to both the short-term results (12.92% vs. 26.19%, p < 0.001; 17.97% vs. 33.33%, p = 0.002, respectively) and the long-term results (19.66% vs. 28.57%, p = 0.017; 21.35% vs. 34.52%, p < 0.001, respectively).ConclusionsRTS3 may be more effective than RTS4 for PPH. However, RTS4 appears to be associated with a lower incidence and severity of CH in the areas of the chest and back than RTS3. NIR intraoperative imaging of thoracic sympathetic ganglions may improve the quality of sympathicotomy surgeries.

Impact of endoscopic thoracic R4 sympathicotomy combined with R3 ramicotomy for primary palmar hyperhidrosis.

Endoscopic thoracoscopic sympathectomy (ETS) is the preferred method for treating primary palmar hyperhidrosis (PPH) that bears the risk of compensatory hyperhidrosis (CH) following surgery. The current study aims to evaluate the effectiveness and safety of an innovative surgical procedure of ETS. A survey of the clinical data of 109 patients with PPH who underwent ETS in our department from May 2018 to August 2021 was retrospectively conducted. The patients were organized into two groups. Group A underwent R4 sympathicotomy combined with R3 ramicotomy. Group B underwent R3 sympathicotomy. Patients were followed up to evaluate the safety, effectiveness and the incidence of postoperative CH of the modified surgical approach. A total of 102 patients completed follow-up, and seven of the total enrolled patients were lost to follow-up, with a loss rate of 6% (7/109). Among these, Group A constitutes 54 cases, group B constitutes 48 cases, and the mean follow-up was 14 months (interquartile range 12-23 months). There was no statistically difference in surgical safety, postoperative efficacy, and postoperative quality of life (QoL) score between group A and group B (p > 0.05). The score of the psychological assessment was higher (p = 0.004) in group A (14.15 ± 2.06) compared to group B (13.30 ± 1.86). The incidence of CH in group A was lower than in group B (p = 0.019). R4 sympathicotomy combined with R3 ramicotomy is safe and effective for PPH treatment, along with a reduced incidence of postoperative CH rate and improved postoperative psychological satisfaction.
