The long-term results of upper dorsal sympathetic ganglionectomy and endoscopic thoracic sympathectomy for palmar 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.

Optimal targeting of sympathetic chain levels for treatment of palmar hyperhidrosis: an updated systematic review

BACKGROUND

Palmar hyperhidrosis involves excessive sweating of the palms, with no known etiology. Endoscopic thoracic sympathectomy (ETS) is a safe and effective treatment for palmar hyperhidrosis, but compensatory hyperhidrosis is a common complication after ETS, leading to reduced patient satisfaction and postoperative quality of life. However, the appropriate level of the sympathetic chain to target with ETS to achieve maximum efficacy and reduce the risk of compensatory hyperhidrosis (CH) is controversial. In this systemic review, we investigated the appropriate level of sympathectomy for palmar hyperhidrosis.

METHODS

PRISMA guidelines were implemented to complete a systematic review. We performed a computerized systematic literature search using PubMed and EMBASE from January 1990 to July 2016. We chose the Cochrane Collaboration's tool and the methodological index for non-randomized studies tool for examining study bias.

RESULTS

A total of 4075 citations were identified, of which 91 were eligible for inclusion, including 68 observational studies and 23 comparative trials. In observational studies, sympathectomies showed similar efficacies for curing PH at different levels. However, T2-free groups (i.e., at levels T3, T4, or T3-T4 combined) could render a lower risk of Horner's syndrome (0 vs. 1.21 ± 0.49%, p = 0.036) and CH (28.75 ± 7.25 vs. 57.46 ± 3.86, p = 0.002) compared with T2 involved. In comparative trials, there were 12 studies describing the comparison between T2-free ETS and T2 involved, and 9 of 12 (75%) showed T2-free ETS could reduce the incidence of CH. Overall, lowering the level and limiting the extent of sympathectomy could reduce the incidence of complications.

CONCLUSIONS

Cumulative data from more than 13,000 patients suggest that ETS is a safe, effective, and reproducible procedure with a high degree of patient satisfaction. Currently available evidence suggests that T2-free ETS may reduce the incidence of compensatory hyperhidrosis without compromising success rates and safety.

The correlation between the method of sympathetic ablation for palmar hyperhidrosis and the occurrence of compensatory hyperhidrosis: a review

BACKGROUND

Upper dorsal sympathectomy achieves excellent long-term results in the treatment of primary palmar hyperhidrosis. Compensatory hyperhidrosis (CHH) remains an unexplained sequel of this treatment, attaining in a small percentage of cases disastrous proportions. It has been claimed that lowering the level of sympathectomy (from T2 to T3 and even T4), substituting resection by other means of ablation, and limiting its extend reduce the occurrence of this sequel. This review was designed to evaluate the validity of these claims.

METHODS

A MEDLINE search was performed for the years 1990--2006 and all publications about thoracoscopic upper dorsal sympathectomy for hyperhidrosis were retrieved.

RESULTS

The search identified 42 techniques of sympathetic ablation. However, pertinent data for the present study were reported for only 23 techniques with multiple publications found only for 10. The only statistically valid results from this review point that T2 resection and R2 transection of the chain (over the second rib) ensue in less CHH than does electrocoagulation of T2. Further comparisons were probably prevented due to the enormous disparity in the reported results, indicating lack of standardization in definitions.

CONCLUSIONS

The compiled results published so far in the literature do not support the claims that lowering the level of sympathetic ablation, using a method of ablation other than resection, or restricting the extend of sympathetic ablation for primary palmar hyperhidrosis result in less CHH. In the future, standardization of the methods of retrieving and reporting data are necessary to allow such a comparison of data.

[Efficacy, side effects and patient satisfaction with wrist conduction block anaesthesia prior to the treatment of palmar hyperhidrosis with botulinum toxin type A]

BACKGROUND

The treatment of palmar hyperhidrosis with botulinum toxin type A (BTX A) injections is one of the most effective therapeutic options. However, without adequate anaesthesia this treatment is not feasible in most patients. The anaesthesia of the radial, median and ulnar nerves (wrist block) is despite the absence of good data considered effective but risky.

PATIENTS AND METHODS

Between 1.10.1999 and 30.9.2001 retrospectively the efficacy, side effects and the patient satisfaction regarding the overall performance of the wrist block prior to the treatment of the palmar hyperhidrosis with BTX A was investigated. The study took place at the department of dermatology in Mannheim.

RESULTS

Of the 38 patients treated, 33 were finally included into the trial. The patients chose the average score of 7,9 +/- 2,1 (sd) on a scale from "0" to "10" (not at all effective--maximally effective) for the efficacy of the wrist block in reducing pain. The patients were very content with the wrist block and granted it the average score of 7,7 +/- 2,1 (sd) on a scale from "0" to "10" (not at all content--maximum content). Unwanted effects could be seen in 31/33 patients (93,9%): these were dizziness, headache or haematoma at the spot of injection as well as pain caused by the injections of the local anaesthesia or paresthesias such as tickling of the hand or arm. All side effects caused by the wrist block were reversible and lasted--except in one patient--only for a short time. 29/33 patients (87,9%) recommended the wrist block prior to treating palmar hyperhidrosis with BTX A and 28/33 patients (84,9%) could not imagine to agree to such a treatment without local anaesthesia.

CONCLUSION

The wrist block effectively reduces pain due to the treatment of palmar hyperhidrosis with BTX A. Major side effects are rare; patient acceptance and satisfaction are high.

From frown lines to fissures: Therapeutic uses for botulinum toxin

INTRODUCTION

Since the pharmacological mode of action of botulinum toxin (BTX) has been elucidated, its therapeutic potential has been increasingly recognised. The aims of this review were to summarize our current understanding of the pharmacological action of this agent and to review its therapeutic uses.

METHODS

An electronic literature search with Medline (January 1965 to December 2004) was carried out to identify articles related to the pharmacological mode of action and clinical uses for botulinum toxin using the keyword "botulinum toxin".

RESULTS AND CONCLUSION

Botulinum toxin A is emerging as a valuable clinical tool, both for diagnostic and therapeutic purposes in a wide variety of disorders, and is already the treatment of choice for selected conditions. Better understanding of its modes of action may identify alternative targets for pharmacological intervention, and may allow development of longer acting drugs with lower immunogenicity. Therapeutic uses of BTX-A must be assessed systematically in prospective studies, and the clinical role of other subtypes requires evaluation.

Percutaneous CT-guided chemical thoracic sympathectomy for patients with palmar hyperhidrosis after transthoracic endoscopic sympathectomy

BACKGROUND

Palmar hyperhidrosis is a common functional disorder in the Asians. Currently, transthoracic endoscopic sympathectomy (TES) is considered to be the treatment of choice for this entity because of its high initial success rate and minimal morbidity. However, primary failure and recurrence of hyperhidrosis occurred in some patients, even with a very low incidence. We present our experience in the treatment of primary failure and recurrence of hyperhidrosis after TES by means of percutaneous computer tomography (CT) guided ethanol thoracic sympathectomy.

METHODS

From July 1999 to July 2001, 11 patients (2 males and 9 females with a mean age of 25.9 years, range: 19-44 years) of this subgroup underwent percutaneous CT-guided chemical thoracic sympathectomy. Failure of the first sympathectomy was caused by severe pleural adhesion (from the previous operative findings) in 7 patients. The remaining 4 patients were recurrent palmar hyperhidrosis. All patients underwent unilateral procedures (3 on the right and 8 on the left).

RESULTS

All patients were followed for at least 2 years after the treatment. Needle puncture was possible without difficulty in all patients. All patients had satisfactory results with minimal complication. No recurrence was noted at follow-up.

CONCLUSION

In summary, percutaneous CT-guided ethanol thoracic sympathectomy could be an easy, safe, and alternative strategy to treat patients with palmar hyperhidrosis after failure or recurrence after TES.

Current Therapeutic Options for Treating Primary Hyperhidrosis

Severe hyperhidrosis can cause extreme embarrassment that may lead to social and professional isolation. Therapeutic strategies to hyperhidrosis should employ the least invasive treatment that provides effective symptom control. The treatment options available for control of hyperhidrosis, non-surgical or surgical, differ in their invasiveness and efficacy. Mechanisms of action of antiperspirants, iontophoresis, cholinergic inhibitor drugs, botulinum toxin, and surgical sympathectomy are reviewed. There is little published evidence in the form of comparative randomised trials to support the use of one treatment over another. However, authors have tended to recommend those therapies that are available to their speciality. Specific therapies should be tailored to the patient's symptoms to gain maximum symptomatic improvement with minimum invasiveness and side-effects. To achieve this, the full range of treatment options should be available to, or accessible by the consulting doctor in order for the patient to have a meaningful choice.

Long-term assessment of percutaneous stereotactic thermocoagulation of upper thoracic ganglionectomy and sympathectomy for palmar and craniofacial hyperhidrosisin 1742 cases

OBJECTIVE

We sought to determine the long-term outcome of percutaneous stereotactic thermocoagulation for upper thoracic ganglionectomy and sympathectomy in patients with palmar and craniofacial hyperhidrosis with the use of a three-dimensional system of coordinates for the location of the T2 and T3 ganglia on the basis of the findings in a cadaveric study.

METHODS

From November 1986 to May 1998, upper thoracic ganglionectomy and sympathectomy with the use of percutaneous stereotactic thermocoagulation were performed in 1688 patients with palmar hyperhidrosis and 54 patients with craniofacial hyperhidrosis as outpatient surgical procedures based on a three-dimensional coordinate system for determining the location of the thermocoagulation point, which was developed by the authors in a cadaveric study. The technique requires only local anesthesia.

RESULTS

After initial thermocoagulation, sweating stopped in 3465 (99.5%) of 3484 sides. Hyperhidrosis recurred within 2 to 59 months of treatment in 268 procedures. All patients in whom hyperhidrosis recurred were retreated successfully, resulting in a final success rate of 99.9%. Complications of treatment included pneumothorax in seven procedures (0.2%) and partial Horner's syndrome in five procedures (0.15%). Decreased plantar sweating was noted during follow-up in 92% of patients.

CONCLUSION

The results of this study indicate that upper thoracic ganglionectomy and sympathectomy performed with the use of percutaneous thermocoagulation are a very effective treatment for palmar and craniofacial hyperhidrosis that provides excellent immediate and long-term results as well as a low complication rate. The method is also effective as a retreatment for recurrences. Our data also suggest that performing ganglionectomy and sympathectomy in both T2 and T3 is unnecessary, because the procedure had equal long-term effectiveness when performed in T2 alone.

Ultra-thin needle thoracoscopic surgery for hyperhidrosis with excellent cosmetic effects

BACKGROUND

In spite of its cosmetic benefits over open surgical techniques, endoscopic sympathectomy using 5 mm or larger instruments still has the problems of operative scar as well as pain on the trocar sites. Recently we have begun using 2 mm endoscopic instruments. The purpose of this study was to confirm the safety and feasibility of fine needle endoscopic instruments in thoracic sympathetic ablation.

METHODS

We have exclusively used 2 mm endoscopic instruments since January 1997, and from that time to May 1999 417 patients were underwent surgical procedures for hyperhidrosis. T2 or T2/T3 sympathectomy was performed for the first 56 patients, after June 1997, in 361 patients the interconnecting sympathetic trunk was divided instead of ganglion resection, and this procedure was named sympathicotomy. Palmar hyperhidrosis was presented in 375 patients (89.9%) and facial in 28 (6.7%) and axillary in 14 (3.4%). The level of division or resection of the ganglion differed according to the patient's symptoms.

RESULTS

Sympathicotomy and sympathectomy were successful and all patients were satisfied with immediate dryness of affected sites. There were not any cases of bleeding or reoperation or hospital mortality. A large endoscope was required to eliminate the pleural adhesion in fourteen cases (7.7%). Thoracotomy conversion was required in two pleural adhesion cases. Minor complications were occurred in 17 patients (4.1%); such as closed thoracostomy in ten cases, peripheral nerve injury in three, pulmonary parenchymal injury in two, Horner's syndrome in two and atrial fibrillation in one. We have five cases of recurrent symptoms (1.2%).

CONCLUSION

Our experience indicates that, for the treatment of hyperhidrosis, 2 mm ultra-thin needle endoscopic instruments are safe and effective to operate on palmar and facial hyperhidrosis patients.
