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

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.

Robotic sympathetic trunk reconstruction for compensatory sweating after thoracic sympathectomy

Objectives

Endoscopic thoracic sympathectomy may be complicated by the onset of disabling compensatory sweating (CS). The objective of this case series is to report the 2-year outcomes after robotic sympathetic trunk reconstruction (STR) for the reversal of CS in patients who had undergone endoscopic thoracic sympathectomy.

Methods

We prospectively followed-up a total of 23 patients who had undergone robotic STR because of intolerable CS between October 2017 and January 2021. A visual analog scale ranging from 0 to 10 (with 10 indicating the highest degree) was used to assess the severity of CS at different anatomical locations, thermoregulatory alterations, and gustatory hyperhidrosis. Measurements were performed before STR and at 6-month and 2-year follow-up.

Results

The mean age of the study participants was 43.3 ± 7.8 years, and 20 (87%) were men. The reversal procedure was performed after a mean of 19.6 ± 7.8 years from endoscopic thoracic sympathectomy. In all patients, nerve defects were successfully bridged using sural nerves (mean length, 9.7 cm on the right and 9.8 cm on the left). No cases of Horner syndrome were noted. At 6 postoperative months, the severity of CS decreased significantly at all body surface areas. The observed improvements were effectively maintained at 24 post-STR months. There was no evidence of either recurrent hyperhidrosis at the primary site or transition of CS to other anatomical locations. Similar improvements were evident for thermoregulatory alterations and gustatory hyperhidrosis.

Conclusions

Robotic STR is safe and effective in reversing intolerable CS after endoscopic thoracic sympathectomy.

Development of a novel nomogram to predict the risk of severe compensatory sweating following endoscopic thoracic sympathectomy

BACKGROUNDS

Endoscopic thoracic sympathectomy (ETS) is a permanent and effective treatment for primary hyperhidrosis and facial blushing; however, severe compensatory sweating (SCS) remains a devastating complication. We aimed to (i) construct a nomogram to predict the risk of SCS, and (ii) investigate factors associated with the level of satisfaction.

METHODS

From Jan 2014 to Mar 2020, 347 patients underwent ETS by a single surgeon. These patients were asked to complete an online questionnaire regarding primary symptom resolution, level of satisfaction, and development of compensatory sweating. Multivariable analysis was conducted via logistic regression and ordinal regression to predict SCS and satisfaction level respectively. Nomogram was developed based on significant predictors.

RESULTS

In total, 298 (85.9%) patients responded to the questionnaire with a mean follow up of 4.9 ± 1.8 years. Significant factors associated with SCS in the nomogram included older age (OR 1.05, 95% CI 1.02-1.09, P = 0.001), primary indication other than palmar hyperhidrosis (OR 2.30, 95% CI 1.03-5.12, P = 0.04), and current smoking (OR 5.91, 95% CI 2.46-14.20, P < 0.001). The area under receiver operating characteristic curve was 0.713. Multivariable analysis revealed that longer follow up (β = -0.201 ± 0.078, P = 0.01), gustatory hyperhidrosis (β = -0.781 ± 0.267, P = 0.003), primary indication other than palmar hyperhidrosis (β = -1.524 ± 0.292, P < 0.001), and SCS (β = -3.061 ± 0.404, P < 0.001) were independently associated with a lower degree of patient satisfaction.

CONCLUSION

The novel nomogram can provide a personalized numerical risk estimate to assist both the clinician and patient weigh the pros and cons as part of the decision-making process, mitigating the chance of patient dissatisfaction.

Plantar hyperhidrosis associated with primary palmar hyperhidrosis: Outcome following video-assisted thoracoscopic sympathectomy

INTRODUCTION

Primary palmar hyperhidrosis is an abnormal over-sweating of palms. It is usually associated with plantar hyperhidrosis. Video-assisted thoracoscopic sympathectomy is the treatment of choice for palmar hyperhidrosis; however, it may affect plantar hyperhidrosis.

OBJECTIVES

The aim of this study was to evaluate the effect of thoracoscopic sympathectomy on plantar hyperhidrosis.

METHODS

This prospective study included patients who presented to the Cardiothoracic Surgery Department with primary palmo-planter hyperhidrosis and received thoracoscopic sympathectomy between January 2014 and December 2018. Preoperatively, patients scored subjectively the degree of palmar and plantar hyperhidrosis on Visual Analogue Scale. Following surgery, scoring was performed at three intervals: 7, 30, and 180 days. Presence of compensatory sweating and its scoring was obtained at the same intervals. Complications and patient satisfaction were recorded.

RESULTS

A total of 518 patients were included. Complication rate, excluding compensatory hyperhidrosis, was 2.7%. Preoperative Visual Analogue Scale score for palmar hyperhidrosis was 9.9 ± 3.8 that following thoracoscopic sympathectomy decreased to 0.041 ± 0.2 on the seventh postoperative day. Further decrease to 0.3 ± 0.16 was noted on the 30th day and 180th day postoperatively. Preoperative Visual Analogue Scale score for plantar hyperhidrosis was 9.54 ± 0.66 that following sympathectomy decreased to 2.27 ± 1.67 on the seventh postoperative day. However, slight insignificant increase was noted to become 2.73 ± 1.65 on the 30th day and 6th month postoperatively. Compensatory hyperhidrosis was recorded in 3.9% of patients at 6th month postoperatively.

CONCLUSION

Palmar hyperhidrosis is usually associated with plantar hyperhidrosis. Thoracoscopic sympathectomy is an effective and safe treatment for palmar hyperhidrosis. It may completely or partially cure plantar hyperhidrosis.

The management of compensatory sweating after thoracic sympathectomy

OBJECTIVE

The main therapeutic method of treatment for local hyperhidrosis is endoscopic thoracic sympathectomy. Generally, resections of the sympathetic trunk or ganglia are performed between the second rib and sixth rib. However, this procedure can result in compensatory sweating, in which excess sweating occurs on the back, chest, and abdomen. Compensatory sweating has been regarded as a thermoregulatory response and thought to be untreatable. This study suggests that compensatory sweating is not a physiologic reaction and is indeed treatable.

METHODS

Eight patients with severe compensatory sweating were treated by observing blood perfusion of the skin with laser speckle flowgraphy, which determines the sympathetic nerves related to the area of skin with compensatory sweating. When intraoperative monitoring with laser speckle flowgraphy indicated the position of compensatory sweating by electrical stimulation of the sympathetic ganglion, ganglionectomy was performed.

RESULTS

The skin domain that each sympathetic nerve controls was able to be detected by laser speckle flowgraphy. In all patients, compensatory sweating was resolved after interruption of the ganglia or sympathetic nerves related to compensatory sweating.

CONCLUSIONS

Our results demonstrate that compensatory sweating is caused by denatured sympathetic nerves influenced by endoscopic thoracic sympathectomy and is not the result of a physiological response. With laser speckle flowgraphy, the sympathetic nerve related to the sweating of various parts of the body could be identified. The treatment of compensatory sweating on the back, chest, and stomach was previously considered to be difficult; however, compensatory sweating is demonstrated to be treatable with this technique.

The etiology, diagnosis, and management of hyperhidrosis: A comprehensive review: Therapeutic options

Hyperhidrosis (HH) is a chronic disorder of excess sweat production that may have a significant adverse effect on quality of life. A variety of treatment modalities currently exist to manage HH. Initial treatment includes lifestyle and behavioral recommendations. Antiperspirants are regarded as the first-line therapy for primary focal HH and can provide significant benefit. Iontophoresis is the primary remedy for palmar and plantar HH. Botulinum toxin injections are administered at the dermal-subcutaneous junction and serve as a safe and effective treatment option for focal HH. Oral systemic agents are reserved for treatment-resistant cases or for generalized HH. Energy-delivering devices such as lasers, ultrasound technology, microwave thermolysis, and fractional microneedle radiofrequency may also be utilized to reduce focal sweating. Surgery may be considered when more conservative treatments have failed. Local surgical techniques, particularly for axillary HH, include excision, curettage, liposuction, or a combination of these techniques. Sympathectomy is the treatment of last resort when conservative treatments are unsuccessful or intolerable, and after accepting secondary compensatory HH as a potential complication. A review of treatment modalities for HH and a sequenced approach are presented.

The relation between age and outcomes of thoracic sympathectomy for hyperhidrosis: The older the better

OBJECTIVE

Several factors may potentially influence the efficacy and patient satisfaction after bilateral thoracic sympathectomy as the treatment for hyperhidrosis, but few studies have specifically analyzed the impact of age on the efficacy of this treatment, the occurrence of compensatory hyperhidrosis (CH), and variations in the quality of life.

METHODS

We retrospectively analyzed the effect of age, body mass index, surgical techniques, quality of life before surgery, betterment in the quality of life after surgery, clinical improvement in sweating at the main site, and the occurrence and intensity of CH in patients with hyperhidrosis (n = 1633) who underwent bilateral sympathectomy.

RESULTS

Quality of life improved in more than 90% of patients, and severe CH occurred in 5.4%. Age did not affect these outcomes. The older, the greater reduction in sweating, and CH was linked to other variables (body mass index, craniofacial hyperhidrosis, and level of resection).

CONCLUSIONS

We observed that patients with old age reported an improvement in sweating in the main site of hyperhidrosis. Sympathectomy outcomes in older patients are similar to those observed in younger patients in terms of quality of life improvement and occurrence of CH.

Long term compensatory sweating results after sympathectomy for palmar and axillary hyperhidrosis

BACKGROUND

Endoscopic thoracic sympathectomy is currently the best treatment for primary upper extremity hyperhidrosis, but the potential for adverse effects, particularly the development of compensatory sweating, is a concern and often precludes surgery as a definitive therapy. This study aims to evaluate long-term results of two-stage unilateral versus one-stage bilateral thoracoscopic sympathectomy.

METHODS

From November 1995 to February 2011, 261 patients with severe palmar and/or axillary hyperhidrosis underwent endoscopic sympathectomy with a follow-up of at least 4 years. One-hundred and twenty-six patients received one-stage bilateral, single port video-assisted thoracoscopic sympathectomy (one-stage group) and 135 patients underwent two-stage unilateral, single-port video-assisted thoracoscopic sympathectomy, with a mean time interval of four months between the procedures (two-stage group).

RESULTS

The mean postoperative follow-up period was 7.2 years (range, 4-9 years). Sixteen patients (12.7%) in the one-stage group and 15 patients (11.1%) in the two-stage group suffered from bradycardia (P=0.15). Recurrences occurred in three patients (2.4%) in the one-stage group and one (0.7%) in the two-stage group (P=0,09). Facial flushing or hyperthermia occurred in eight patients (6.3%) in the one-stage group and 11 (8.1%) of the two-stage group. Compensatory sweating occurred in 27 patients (21.4%) in the one-stage group and six patients (4.4%) in the two-stage group (P=0.0001). However, compensatory sweating recovered in five patients (83.3%) in the two-stage group versus nine (33.35%) in one-stage group during the follow-up period (Log-rank test P=0.016; HR, 7.196; 95% CI, 1.431-36.20). An improvement in postoperative quality of life (QoL) scores was observed in at least 90% of patients at three years after surgery in the one-stage group and at least 95% of patients in the two-stage group (P=0.001).

CONCLUSIONS

Compensatory sweating seems to improve during the follow-up period with a higher recovery rate after two-stage unilateral versus one-stage bilateral sympathectomy for patients with palmar and axillary hyperhidrosis.

Compensatory sweating after restricting or lowering the level of sympathectomy: a systematic review and meta-analysis

OBJECTIVE

To compare compensatory sweating after lowering or restricting the level of sympathectomy.

METHOD

A systematic review and meta-analysis were conducted of all randomized controlled trials published in English that compared compensatory sweating after lowering or restricting the level of sympathectomy. The Cochrane collaboration tool was used to assess the risk of bias, and the Mantel-Haenszel odds ratio method was used for the meta-analysis.

RESULTS

A total of 11 randomized controlled trials were included, including a total of 1079 patients. Five of the randomized controlled trials studied restricting the level of sympathectomy, and the remaining six studied lowering the level of sympathectomy.

CONCLUSIONS

The compiled randomized controlled trial results published so far in the literature do not support the claims that lowering or restricting the level of sympathetic ablation results in less compensatory sweating.

A comparison between two types of limited sympathetic surgery for palmar hyperhidrosis

PURPOSE

Endoscopic thoracic sympathetic surgery is effective for treating palmar hyperhidrosis, although compensatory sweating (CS) is a significant and annoying side effect. The purpose of this study was to compare the results of limited resection at two different locations.

METHODS

From May 2004 to June 2009, T3 sympathicotomy (group I) was performed in 46 patients and T3,4 ramicotomy (group II) was performed in 43 patients during the same period. T3 sympathicotomy (group I) and T3,4 ramicotomy (group II) were performed during the same period. Using questionnaires, completed by the patients, the satisfaction rates and grades of CS were analyzed.

RESULTS

No significant differences in age distribution or sex ratios were observed between the two groups. The satisfaction rate was 91.3 % in group I and 79.1 % in group II. The operation time was 19.8 (±6.6) min in group I, and 51.6 (±18.8) min in group II, showing a statistically significant difference (p < 0.002). The incidence of persistent hand sweating in group II (16.3 %) was higher than that observed in group I (2.2 %). The incidence of compensatory sweating on the lower extremities was higher in group II (37.2 %) than in group I (10.9 %).

CONCLUSIONS

Although ramicotomy is considered to be an effective method for treating hyperhidrosis and has a theoretical advantage of allowing greater anatomical resection, it requires longer operation time and induces more severe compensatory sweating in the lower limbs resulting in reduced satisfaction rates.
