Transection of more than one sympathetic chain ganglion for hyperhidrosis increases the severity of compensatory hyperhidrosis and decreases patient satisfaction

Efficacy and Safety of Botulinum Toxin B in Focal Hyperhidrosis: A Narrative Review

Botulinum toxin type B (BoNT-B), known as Myobloc® in the United States and as Neurobloc® in Europe, is a new therapeutically available serotype among the botulinum toxin family. During the last years several data have been reported in literature investigating its efficacy and safety, as well as defining the dosing and application regiments of BoNT-B in the treatment of hyperhidrosis. Moreover, recent studies have been examining its safety profile, which may be different from those known about BoNT-A. The aim of this review is to provide information about what is currently known about BoNT-B in regards to the treatment of focal hyperhidrosis.

Use of thoracoscopy for thoracic sympathetic nerve block in primary hyperhidrosis

Thoracic sympathetic nerve block (TSNB) has been widely used in the treatment of neuropathic pain. To reduce block failure rates, TSNB is assisted with several modalities including fluoroscopy, computed tomography, and ultrasonography. The present study describes our experience assessing the usefulness of thoracoscopy in TSNB for predicting compensatory hyperhidrosis before sympathectomy in primary hyperhidrosis. From September 2013 to October 2021, TSNB was performed under local anesthesia using a 2-mm thoracoscope in 302 patients with severe primary hyperhidrosis. Among the 302 patients, 294 were included for analysis. The target level of TSNB was T3 in almost all patients. The mean procedure time was 21 min. Following TSNB, the mean temperature of the left and right palms significantly changed from 31.5 to 35.3 °C and from 31.5 to 34.8 °C, respectively. With TSNB, primary hyperhidrosis was relieved in all patients. Pneumothorax occurred in six patients, in which no chest tube insertion was required. One patient developed hemothorax and was discharged the next day after small-bore catheter drainage. Transient ptosis developed in 10 patients and improved within a day in all patients. Our experiences showed that thoracoscopic TSNB is accurate, safe, and feasible to block the thoracic sympathetic nerve in patients with severe primary hyperhidrosis.

Selective T3-T4 sympathicotomy versus gray ramicotomy on outcome and quality of life in hyperhidrosis patients: a randomized clinical trial

Compensatory hyperhidrosis is the leading cause of patients' dissatisfaction after thoracic sympathicotomy. The study aimed to reduce compensatory hyperhidrosis to increase patients’ satisfaction. A prospective randomized study on palmar hyperhidrosis, May 2016–September 2019. Twenty-one patients T₃–T₄ sympathicotomy and 21 T₃–T₄ gray ramicotomy. Data prospectively collected. Analysis at study's end. Focus on the sweating, temperature, quality of life baseline and postoperatively, compensatory hyperhidrosis, hand dryness, patients' satisfaction, and if they would undergo the procedure again and recommend it. No baseline differences between groups. Hyperhidrosis was controlled postoperatively in all patients. No mortality, serious complications, or recurrences. Sympathicotomy worse postoperative quality of life (49.05 (SD: 15.66, IR: 35.50–63.00) versus ramicotomy 24.30 (SD: 6.02, IR: 19.75–27.25). After ramicotomy, some residual sweating on the face, hands, and axillae. Compensatory sweating worse with sympathicotomy. Satisfaction higher with ramicotomy. Better results with ramicotomy than sympathicotomy regarding hand dryness, how many times a day the patients had to shower or change clothes, intention to undergo the procedure again or recommend it to somebody else, and how bothersome compensatory hyperhidrosis was. T₃–T₄ gray ramicotomy had better results than T₃–T₄ sympathicotomy, with less compensatory sweating and higher patients' satisfaction.

Thoracoscopic sympathetic block to predict compensatory hyperhidrosis in primary hyperhidrosis

Background

Compensatory hyperhidrosis is the main cause of patients’ dissatisfaction following sympathectomy for primary hyperhidrosis. Therefore, thoracoscopic sympathetic nerve block before sympathectomy can be used to predict compensatory hyperhidrosis after sympathectomy. The objective of this study is to review our recent experience with the nerve block procedure, describing efficacy, safety and validity.

Methods

We retrospectively reviewed the medical records of 107 patients who underwent thoracoscopic sympathetic nerve block with a local anesthetic for primary palmar and craniofacial hyperhidrosis using a 2-mm needlescope from March 2017 to November 2019. A week later, the patients were interviewed, and a decision made as to whether to proceed with sympathectomy. We analyzed the perioperative data of patients who underwent the predictive procedure either followed, or not followed, by sympathectomy.

Results

Primary hyperhidrosis was relieved in all patients by the predictive procedure without severe complications. Compensatory hyperhidrosis happened to 32 patients (29.9%). Seventy-eight patients (72.9%) decided to undergo sympathectomy (group A) and 29 patients (27.1%) refused the sympathectomy (group B). Group B tended to have higher average body mass index (24.5 versus 23.2 kg/m², P=0.082) and compensatory hyperhidrosis rate after predictive procedure (37.9% versus 26.9%, P=0.269) compared to group A. The compensatory hyperhidrosis rate after sympathectomy in group A was 76.9%. The effective duration of sympathetic block was significantly longer in group A than in group B (33.5 versus 13.9 hours, P=0.001). The predictive procedure had 94.4% specificity and 33.3% sensitivity for prediction of compensatory hyperhidrosis.

Conclusions

Thoracoscopic sympathetic block may be safe and feasible as a procedure for predicting compensatory hyperhidrosis after sympathectomy, and beneficially, it allows the patients to experience the effect of sympathectomy on primary hyperhidrosis and occurrence of compensatory hyperhidrosis. However, a longer effective duration of sympathetic block is needed to help patients to decide whether to proceed with the surgery.

Impact of Thoracoscopic T2 Sympathectomy on Patients With Primary Palmar and Axillary Hyperhidrosis

BACKGROUND

There are different techniques for thoracoscopic sympathectomy for management of primary hyperhidrosis. Each technique has the advantage of giving good surgical results, but may cause complications, which depend on the level of sympathectomy used in each technique.

METHODS

From October 2012 to August 2016, a total number of 120 patients (of primary palmar and axillary hyperhidrosis) were enrolled in this prospective randomized study. Patients were randomized preoperatively and divided into 2 groups: group A (underwent T2, T3, and T4 sympathectomy) and group B (underwent T3 and T4 sympathectomy) with 1 year of follow-up. Improvement of palm sweating, development of complications, patient satisfaction, and quality of life were evaluated.

RESULTS

Family history was positive in 33 patients (55%) in group A and in 31 patients (52%) in group B. All patients had improvement of hand sweating. Overdry hands were significant in group A (p = 0.032). Compensatory sweating was significant in group A after the first month (p = 0.016), after 6 months (p = 0.022), and after 12 months (p = 0.025). In group B, very satisfied patients were significant after 6 and 12 months (p = 0.002 and 0.000, respectively).

CONCLUSIONS

Limited sympathectomy to the level of T3 and T4 has the same therapeutic effect obtained by T2, T3, and T4 sympathectomy with less complications, greater patient satisfaction, and better quality of life. It should be the technique of choice for treatment of primary palmar and axillary hyperhidrosis.

Compensatory hyperhidrosis after different surgeries at the same sympathetic levels: a meta-analysis

Background

Different techniques of video-assisted thoracoscopic sympathetic surgery have become the radical treatments for palmar and axillary hyperhidrosis (AH). However, there is no consensus over which technique can make a minimal incidence of compensatory hyperhidrosis (CH). This study was designed to compare the incidence of CH after different techniques at the same sympathetic levels in the treatment of upper limb and facial hyperhidrosis (FH).

Methods

The databases of PubMed, Web of Science, ScienceDirect, Ovid Medline, Embase, and Cochrane Library were searched to identify studies comparing different surgical techniques at the same sympathetic levels for upper limb and FH. The data was analyzed by Revman 5.3 software.

Results

A total of ten studies involving 896 patients were included, of whom 149 underwent sympathectomy, 435 underwent sympathicotomy, and 312 under endoscopic sympathetic clip (ESC). Meta-analysis showed that the difference of incidence of CH and patients' satisfaction was not significant between sympathectomy and sympathicotomy (P=0.05, 0.19, respectively). But, the incidence of CH is significant lower after ESC than after sympathicotomy (OR: 1.58, 95% CI: 1.04-2.38, P=0.03). However, the incidence of moderate/severe CH between these two groups is not significant different (OR: 1.49, 95% CI: 0.93-2.39, P=0.10).

Conclusions

If only CH and the same sympathetic levels concerned, sympathectomy and sympathicotomy is equal for upper limb hyperhidrosis and FH. And, ESC should be recommended for a lower incidence of CH, comparing with sympathicotomy.

A retrospective review on minimally invasive technique via endoscopic thoracic sympathectomy (ETS) in the treatment of severe primary hyperhidrosis: Experiences from the National Heart Institute, Malaysia

Background: Hyperhidrosis is due to the hyperactive autonomic stimulation of the sweat glands in response to stress. Primary hyperhidrosis is a common yet psychologically disabling condition. This study will describe our experience in managing hyperhidrosis via endoscopic thoracic sympathectomy (ETS).

Methods: The information was obtained from the patient records from 1 ^st January 2011 until 31 ^st December 2016. Pertinent information was extracted and keyed into a study proforma.

Results:  150 patients were operated on but only 118 patients were included in this study. The mean age was 22.9±7.3 years. The majority (54.2%) had palmar-plantar hyperhidrosis and 39.8% had associated axillary hyperhidrosis. Excision of the sympathetic nerve chain and ganglia were the main surgical technique with the majority (55.9%) at T2-T3 level. Mean ETS procedure time was 46.6±14.29 minutes with no conversion. Surgical complications were minimal and no Horner’s Syndrome reported. Mean hospital stay was 3.5±1.05 days. The majority of patients (67.8%) had only one follow-up and only half of the study sample (58.5%) complained mild to moderate degree of compensatory sweating, even though the long-term resolution is yet to be determined by another study. Following ETS, 98.3% of patients had instant relief and resolved their palmar hyperhidrosis. Predictors of CS were sympathectomy level and follow-up. The odds of reporting CS was 2.87 times in patients undergoing ETS at the T2-T3 level compared to those undergoing ETS at the T2-T4 level. The odds of reporting CS was 13.56 times in patients having more than one follow-up compared to those having only one follow-up.

Conclusion: We conclude that ETS is a safe, effective and aesthetically remarkable procedure for the treatment of primary hyperhidrosis  with only half of the patients developing mild to moderate degree of CS. Significant predictors of CS were sympathectomy level during ETS and frequency of follow-up after ETS.

Regret in Surgical Decision Making: A Systematic Review of Patient and Physician Perspectives

OBJECTIVE

Regret is a powerful motivating factor in medical decision making among patients and surgeons. Regret can be particularly important for surgical decisions, which often carry significant risk and may have uncertain outcomes. We performed a systematic review of the literature focused on patient and physician regret in the surgical setting.

METHODS

A search of the English literature between 1986 and 2016 that examined patient and physician self-reported decisional regret was carried out using the MEDLINE/PubMed and Web of Science databases. Clinical studies performed in patients and physicians participating in elective surgical treatment were included.

RESULTS

Of 889 studies identified, 73 patient studies and 6 physician studies met inclusion criteria. Among the 73 patient studies, 57.5% examined patients with a cancer diagnosis, with breast (26.0%) and prostate (28.8%) cancers being most common. Interestingly, self-reported patient regret was relatively uncommon with an average prevalence across studies of 14.4%. Factors most often associated with regret included type of surgery, disease-specific quality of life, and shared decision making. Only 6 studies were identified that focused on physician regret; 2 pertained to surgical decision making. These studies primarily measured regret of omission and commission using hypothetical case scenarios and used the results to develop decision curve analysis tools.

CONCLUSION

Self-reported decisional regret was present in about 1 in 7 surgical patients. Factors associated with regret were both patient- and procedure related. While most studies focused on patient regret, little data exist on how physician regret affects shared decision making.

Thoracic sympathectomy for hyperhidrosis: from surgical indications to clinical results

Sympathectomy and its variations have been performed in thoracic surgery for more than 100 years. However, its indications have undergone profound modifications in this period. Likewise, since then the surgical technique has also evolved dramatically up to the minimally invasive techniques worldwide accessible in present days. Currently, primary hyperhidrosis is, by far, the main indication for thoracic sympathectomy and this procedure is usually carried out thoracoscopically with excellent results. However, until today, hyperhidrosis is a part of thoracic surgery still surrounded by controversy, persisting as an open field over which some confusion still resides regarding its pathophysiology, terms definitions and operative approaches. The aim of this article is to provide a wide but easily comprehensible review of the theme, discussing and clarifying the major concepts with respect to its clinical presentation, all the presently available treatment options and strategies with their potential benefits and risks, the adequate patient selection for sympathectomy, as well as the postoperative clinical results.

Prediction of compensatory hyperhidrosis with botulinum toxin A and local anesthetic

OBJECTIVE

Compensatory hyperhidrosis (CH) is one of the most problematic complications of sympathectomy, which occurs often and is hard to treat. A predictive procedure (PP) for CH can help patients experience compensatory sweating before sympathectomy to determine whether or not to perform sympathectomy. Our study aimed to evaluate the CH after the PP and sympathectomy in patients with primary palmar hyperhidrosis using multiple drugs.

METHODS

We reviewed 83 patients who underwent a PP between July 2009 and August 2013 with primary palmar hyperhidrosis. In group A, we used levobupivacaine (n = 39). In group B, we used botulinum toxin A plus ropivacaine for the PP in group B (n = 44).

RESULTS

The CH rate after the PP was 44 % (group A) and 25 % (group B), and after sympathectomy 80 % (group A) and 75 % (group B). The prediction value between the PP and the sympathectomy was statistically significant in group A (p < 0.05). The positive prediction rate was 73 % and the negative prediction rate was 27 % in group A.

CONCLUSIONS

Local anesthetic alone has a better predictive value. From our finding, patients should be made aware that CH after sympathectomy is less severe in 73 % of cases than that experienced in the PP.

Treatment of compensatory hyperhidrosis after sympathectomy with botulinum toxin and anticholinergics

PURPOSE

Compensatory hyperhidrosis (CH) is the most common adverse complication of sympathectomy. It often has a major negative impact on life quality. No efficient treatment of CH is available. We report nine cases of CH after sympathectomy, which were treated with botulinum toxin A/B (BTX) and anticholinergics.

METHODS

The patients responded to a dermatology life quality index (DLQI) questionnaire before injections with BTX and 3 weeks after treatment. At the follow-up visit, the participants also ranked the effect of the treatment on a five-grade scale. Three patients had residual sweating after BTX treatment, and received additional anticholinergics at the follow-up visit. Those subjects eventually had a third evaluation with the DLQI.

RESULTS

The DLQI score was, on average, 16.4 before treatment and decreased to 4.8 after BTX injections. Eight out of nine patients were satisfied with the treatment. The average DLQI score decreased to 2.2 when the patients with residual sweating (n = 3) received additional anticholinergics. Adverse events from BTX were mild and temporary, but dry mouth was substantial in one patient using anticholinergics.

CONCLUSIONS

A combination of BTX A/B and anticholinergics alleviated the hyperhidrosis with minor side-effects. We consider this treatment safe, effective, and well tolerated.

Quality of life after sympathetic surgery at the T4 ganglion for primary hyperhidrosis: clip application versus diathermic cut

INTRODUCTION

Limited procedures at the T4 ganglion show low rates of compensatory sweating (CS). The aim of the study was to compare endoscopic sympathetic block (ESB) via clip application with endothoracic sympathicotomy (ETS) via diathermy with special regard on patients' quality of life (Qol).

PATIENTS AND METHODS

Treatment success, side effects and patient satisfaction were evaluated in a prospectively gathered database of a tertiary-care referral hospital. Two disease-specific Qol questionnaires were used (Keller, Milanez de Campos).

RESULTS

406 operations were performed in 205 patients (ESB4 N = 114, ETS4 N = 91) with a median follow-up of 12 months. Both procedures improved Qol significantly (P < 0.001) and the degree of improvement was equal in both groups. Palmar and axillary HH were ameliorated after both procedures (P < 0.001). Accordingly, plantar HH decreased after ESB4 (P = 0.002), while remaining unaltered after ETS4. Nineteen patients (9.3%) reported CS and 10 patients (4.9%) judged it as "disturbing". Nine of the latter belonged to the ETS4 group compared to one ESB patient (P = 0.015). Patients developed higher rates of plantar CS after ETS4 compared to ESB4 (P = 0.006). Five patients (2.4%) from both cohorts reported persistence of axillary HH. Recurrence of axillary symptoms was found in 5 ESB4 patients. Satisfaction rates did not differ significantly.

CONCLUSION

Patients' Qol and satisfaction rates are similar in both treatment groups for upper limb HH. Outcome and recurrence rates speak in the favor of ETS4, severity of CS and potential reversibility argue for ESB4.

Thoracoscopic excision of the sympathetic chain: an easy and effective treatment for hyperhidrosis in children

BACKGROUND

Thoracoscopic sympathectomy (TS) is an effective treatment for hyperhidrosis. Various surgical approaches are described in the literature. We describe the technique of thoracoscopic excision of the sympathetic chain done exclusively in children younger than 13 years.

METHODS

All patients younger than 13 years who underwent TS from 2006 at a single institution were prospectively identified and fully evaluated with emphasis on demographic data, age, surgical management, complications and follow-up. All patients were contacted again at the end of 2009 to complete a follow-up questionnaire.

RESULTS

Twelve patients underwent TS between 2006 and 2009. Age ranged from 6 to 13 years. This involved T2-T3 excision for nine patients with isolated palmar hyperhidrosis, and T2-T3-T4 excision for three with additional axillary hyperhidrosis. Six underwent bilateral TS at the same session and six underwent unilateral TS for the dominant side. Four of them had their contralateral operation performed 2-3 months later. Dry limbs were immediately achieved in all patients. Compensatory sweating (CS) was noted in eight patients. Complications included transient ptosis in two and mild recurrence in one.

CONCLUSIONS

Thoracoscopic excision of the sympathetic chain is a simple and safe procedure that relieves hyperhidrosis in all cases and significantly improves the quality of life.

Endoscopic transthoracic limited sympathotomy for palmar-plantar hyperhidrosis: outcomes and complications during a 10-year period

OBJECTIVE

To review surgical results of endoscopic transthoracic limited sympathotomy for palmar-plantar hyperhidrosis during the past decade.

PATIENTS AND METHODS

We retrospectively reviewed 155 consecutive patients who underwent surgery from June 30, 2000, through December 31, 2009, for medically refractory palmar-plantar hyperhidrosis using a technique of T1-T2 sympathotomy disconnection, designed for successful palmar response and minimization of complications.

RESULTS

Of the 155 patients, 44 (28.4%) were male, and 111 (71.6%) were female; operative times averaged 38 minutes. No patient experienced Horner syndrome, intercostal neuralgia, or pneumothorax. The only surgical complication was hemothorax in 2 patients (1.3%); in 1 patient, it occurred immediately postoperatively and in the other patient, 10 days postoperatively; treatment in both patients was successful. All 155 patients had successful (warm and dry) palmar responses at discharge. Long-term follow-up (>3 months; mean, 40.2 months) was obtained for 148 patients (95.5%) with the following responses to surgery: 96.6% of patients experienced successful control of palmar sweating; 69.2% of patients experienced decreased axillary sweating; and 39.8% of patients experienced decreased plantar sweating. At follow-up, 5 patients had palmar sweating (3 patients, <3 months; 1 patient, 10-12 months; 1 patient, 16-18 months). Compensatory hyperhidrosis did not occur in 47 patients (31.7%); it was mild in 92 patients (62.2%), moderate in 7 patients (4.7%), and severe in 2 patients (1.3%).

CONCLUSION

In this series, a small-diameter uniportal approach has eliminated intercostal neuralgia. Selecting a T1-T2 sympathotomy yields an excellent palmar response, with a very low severe compensatory hyperhidrosis complication rate. The low failure rate was noted during 18 months of follow-up and suggests that longer follow-up is necessary in these patients.

T2-T4 sympathectomy versus T3-T4 sympathicotomy for palmar and axillary hyperhidrosis

OBJECTIVE

To evaluate and compare the immediate and long-term outcomes of videothoracoscopic T2-T4 sympathectomy and T3-T4 sympathicotomy for the treatment of palmar and axillary hyperhidrosis.

METHODS

Between October 1993 and September 2007, we treated a total of 88 patients affected by palmar and axillary hyperhidrosis. Twenty-four patients underwent T2-T4 sympathectomy with 5-10 mm trocars (Group A), 43 T2-T4 sympathectomy with 2-5 mm trocars (Group B), 15 T3-T4 sympathicotomy with 5-10 mm trocars and 6 T3-T4 ganglion block with 2-5 mm trocars (Group C). The mean operative time, for each side, was 15 min for sympathicotomy and 28 min for sympathectomy. In September 2008, we recontacted 98% of patients (total 86), by telephone, to establish long-term results (follow-up range 1-15 years).

RESULTS

In this series, we did not find any significant difference between T2-T4 sympathectomy and T3-T4 sympathicotomy in terms of postsurgical palmar anhidrosis or onset of compensatory hyperhidrosis, while both methods show high efficacy for remission of palmar hyperhidrosis. The slightly higher recurrence rate in our early experience (Group A) can be attributed to the learning curve. Using smaller trocars (2-5 mm), we reduced postsurgical intercostal pain and obtained better aesthetic results and a higher grade of patient's satisfaction.

INTERPRETATION

Thoracoscopic approach to hyperhidrosis has evolved in the last few decades with a consequent decrease in side effects. In this series, all patients experienced an improvement in quality of life even in case of recurrence or onset of compensatory hyperhidrosis. Due to these results, the shorter operative time and easier performance of sympathicotomy, we prefer this method.

Clinical consequences of reinnervation disorders after focal peripheral nerve lesions

Axonal regeneration and organ reinnervation are the necessary steps for functional recovery after a nerve lesion. However, these processes are frequently accompanied by collateral events that may not be beneficial, such as: (1) Uncontrolled branching of growing axons at the lesion site. (2) Misdirection of axons and target organ reinnervation errors, (3) Enhancement of excitability of the parent neuron, and (4) Compensatory activity in non-damaged nerves. Each one of those possible problems or a combination of them can be the underlying pathophysiological mechanism for some clinical conditions seen as a consequence of a nerve lesion. Reinnervation-related motor disorders are more likely to occur with lesions affecting nerves which innervate muscles with antagonistic functions, such as the facial, the laryngeal and the ulnar nerves. Motor disorders are better demonstrated than sensory disturbances, which might follow similar patterns. In some instances, the available examination methods give only scarce evidence for the positive diagnosis of reinnervation-related disorders in humans and the diagnosis of such condition can only be based on clinical observation. Whatever the lesion, though, the restitution of complex functions such as fine motor control and sensory discrimination would require not only a successful regeneration process but also a central nervous system reorganization in order to integrate the newly formed peripheral nerve structure into the prepared motor programs and sensory patterns.

[Primary hyperhidrosis. Current status of surgical treatment]

Primary hyperhidrosis-PH is an excessive sweating without known etiology. The PH is more frequent in women and in palms, soles and axillae. Medical treatment is not effective. The objective of the surgery is to remove or to disconnect sympathetic ganglia T2 (craniofacial PH or facial blushing), T3 (palmar PH) and T3-T4 (axillary PH). The surgical techniques are mainly resection/transection, ablation with electrocoagulation, sympathetic block by clipping and radiofrequency. Anhidrosis is achieved in 95% of the patients. The overall rate of complications is less than 5% and these are minor complications. The most important unwanted effect is reflex sweating, presented in 48% of the patients. Reflex sweating is more frequent in back, thorax and abdomen and it appears independently of the surgical technique. Ninety percent of the patients are very satisfied after surgery. Nowadays, thoracic sympathetic surgery is the gold standard for primary hyperhidrosis.
