Thoracodorsal sympathectomy for severe hyperhydrosis: posterior bilateral versus unilateral staged sympathectomy

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.

Single stage bilateral uniportal videothoracoscopic sympathicotomy for hyperhidrosis: can it be managed as an outpatient procedure?

INTRODUCTION

The videothoracoscopic approach is minimally invasive with benefits that include less postoperative pain and shorter hospital stay. It is also a safe procedure which can be performed on an outpatient basis.

AIM

To determine whether videothoracoscopic sympathicotomy can be performed safely in most patients as an outpatient procedure.

MATERIAL AND METHODS

Between July 2005 and October 2015, a total of 92 patients underwent bilateral and single port thoracoscopic sympathicotomy in our department on an outpatient basis. The level of sympathicotomy was T2 in 2 (2.2%) patients, T2 to T3 in 31 (33%) patients, T2 to T4 in 46 (50%) patients and T3 to T4 in 12 (13%) patients. Demographic data, length of postoperative stay, substitution index (SI), admission rate (AR) and readmission rate (RR), complications and patient satisfaction were reviewed retrospectively.

RESULTS

Two (2.2%) patients suffered from chest pain, while 4 (4.3%) patients complained about pain at the port site. Mean discharge time after surgery was 5.1 h (range: 4-6 h), mean duration of hospital stay was 0.15 days (0-3 days) postoperatively and the mean operation time was 43.6 min (15-130 min). In 8 (8.6%) patients, pneumothorax was detected on postoperative chest X-ray, while 5 (5.4%) patients required chest tube drainage. Mild or moderate compensatory sweating developed in 32 (34.7%) patients. No recurrence was observed, and the satisfaction rate was 96.7%. Substitution index and admission rate were 91.3% and 11% respectively, while RR was 0%.

CONCLUSIONS

Bilateral video-assisted thoracoscopic sympathicotomy can be performed safely in most patients as an outpatient procedure.

Evaluation of the effectiveness of thoracic sympathectomy in the treatment of primary hyperhidrosis of hands and armpits using the measurement of skin resistance

Introduction

Hyperhidrosis is excessive sweating beyond the needs of thermoregulation. It is disease which mostly affects young people, often carrying a considerable amount of socio-economic implications. Thoracic sympathectomy is now considered to be the "gold standard" in the treatment of idiopathic hyperhidrosis of hands and armpits.

Aim

Assessment of early effectiveness of thoracic sympathectomy using skin resistance measurements performed before surgery and in the postoperative period.

Material and methods

A group of 20 patients with idiopathic excessive sweating of hands and the armpit was enrolled in the study. Patients underwent two-stage thoracic sympathectomy with resection of Th2-Th4 ganglions. The skin resistance measurements were made at six previously designated points on the day of surgery and the first day after the operation.

Results

In all operated patients we obtained complete remission of symptoms on the first day after the surgery. Inhibition of sweating was confirmed using the standard starch iodine (Minor) test. At all measurement points we obtained a statistically significant increase of skin resistance, assuming p < 0.05. To check whether there is a statistically significant difference in the results before and after surgery we used sequence pairs Wilcoxon test.

Conclusions

Thoracic sympathectomy is an effective curative treatment for primary hyperhidrosis of hands and armpits. Statistically significant increase of skin resistance in all cases is a good method of assessing the effectiveness of the above surgery in the early postoperative period.

Is age group a predictive factor for satisfaction among patients undergoing sympathectomy to treat hyperhidrosis?

OBJECTIVE: Video-assisted thoracic sympathectomy is currently the procedure of choice for the definitive treatment of primary hyperhidrosis, because it is an effective, safe, and minimally invasive method. In the search for better quality of life indexes, all researchers look for predictive factors indicating better surgical outcomes. Failure in the primary treatment, postoperative compensatory hyperhidrosis, body mass index over 25, level of resection of the sympathetic chain, and extent of resection are some of the factors that may negatively influence the results. The objective of this study was to compare, according to the age group, the quality of life after bilateral thoracic sympathectomy for treatment of primary hyperhidrosis in a cohort of 1,644 patients. METHODS: From February 2000 to October 2008, data were collected from 1,644 patients with palmar (71%) or axillary (29%) hyperhidrosis who underwent video-assisted thoracic sympathectomy. The patients were divided into three groups according to their ages. The first group consisted of patients up to 17 years-old, the second from 18 to 30 years-old, and the third of over 30 years-old. All patients had a body mass index of less than 25. RESULTS: In the evaluation 30 days after surgery, improvement of the quality of life in the three groups was observed. There was no significant difference between the age groups. In the present study, 91.9% of the patients presented compensatory hyperhidrosis, with no difference between the age groups. CONCLUSIONS: Patients with primary hyperhidrosis experience quality of life improvement after thoracic sympathectomy regardless of their age.

Is gender a predictive factor for satisfaction among patients undergoing sympathectomy to treat palmar hyperhidrosis?

Video-assisted thoracic sympathectomy (VATS) is currently the procedure of choice for the definitive treatment of primary hyperhidrosis because it is an effective, safe, and minimally invasive method. The aim of VATS treatment is to improve the quality of life through the reduction of excessive sudoresis. The purpose of this study was to assess the quality of life after VATS for treating palmar hyperhidrosis according to gender.

METHODS

A total of 1044 patients who submitted to the surgical treatment for palmar hyperhidrosis from June 2000 to February 2008 were retrospectively evaluated. The patients were divided into two groups according to gender [719 (68.8%) females and 325 (31.2%) males].

RESULTS

There are no statistically significant differences between genders with regard to the quality of life in palmar hyperhidrosis patients (p = 0.726). In the interview that was performed 30 days after surgery, the quality of life in the two groups had improved, with no statistical difference between the groups.

CONCLUSION

Patients with palmar hyperhidrosis present with an improvement in the quality of life after VATS regardless of gender.

Thoracoscopic sympathectomy for palmar and axillary hyperhidrosis: four-year outcome and quality of life after bilateral 5-mm dual port approach

BACKGROUND

During recent years, thoracoscopic sympathectomy has been the standard treatment for hyperhidrosis. Different surgical techniques have been described without proving their advantages compared with other procedures. This study was designed to evaluate our modification of thoracoscopic sympathectomy and to compare the effectiveness between axillary and palmar hyperhidrosis.

METHODS

Ninety patients with axillary or palmar hyperhidrosis who underwent bilateral thoracoscopic sympathectomy with single-lumen ventilation with a dual 5-mm port approach were followed up for a median of 3.9 (range, 1-6) years. The clinical course and data during the hospitalization and consultation in our outpatient clinic were reviewed. The following parameters were evaluated: clinical improvement, satisfaction, changes in quality of life, and compensatory sweating and gustatory sweating.

RESULTS

The perioperative mortality was 0, and the morbidity was 6.5%. In 81% clinical improvement of sweating was noticed; 55% did not sweat at all. A total of 88% of patients were satisfied with the result of the operation. The rates of compensatory sweating and gustatory sweating were 93.5% and 49.4%, respectively. The result of sympathectomy in patients with palmar hyperhidrosis were significantly better concerning rate of satisfaction (p = 0.006) and improvement of symptoms (p = 0.027) compared with patients with axillary symptoms. Additionally it was found that the compensatory sweating had significantly impacted the satisfaction rating of the operation.

CONCLUSION

Currently different effective surgical approaches for the treatment of hyperhidrosis with improvement rates of more than 80% are available. The quality of the intervention has to be evaluated by changes in quality of life and intensity of compensatory sweating. Thoracoscopic sympathectomy as performed in our institution offers results and complications comparable to previously published trials; however, because of single-lumen ventilation the management is much easier. Therefore, this technique offers an interesting option for the treatment of patients with palmar and axillary hyperhidrosis.

The body mass index and level of resection: predictive factors for compensatory sweating after sympathectomy

OBJECTIVE

Compensatory sweating (CS) is the most common adverse event and the main cause of dissatisfaction among patients undergoing a VATS sympathectomy for the treatment of primary hyperhidrosis. It has been described that obese individuals experience more sweating than thinner ones. The aim of this study is to identify the Body Mass Index (BMI) and the level of resection as predictive factors for CS and its relation to levels of patient satisfaction following the procedure.

METHODS

From October 1998 to June 2003, 102 patients undergoing VATS sympathectomies (51 for palmar hyperhidrosis, PH, and 51 for axillary hyperhidrosis, AH) were prospectively surveyed. They were divided into three groups according to their BMI: Group I was composed of 19 patients with BMI<20 (9 patients with PH and 10 with AH); Group II was composed of 52 patients with 20 < or =BMI<25 (25 with PH and 27 with AH); and Group III was composed of 31 patients with BMI > or =25 (17 with PH and 14 with AH). Each procedure was simultaneously and bilaterally performed under general anesthesia using two 5.5 mm trocars and a 30 degrees optic system.

RESULTS

Patients treated for PH (resection of T2-T3) had more severe CS than those with AH (resection of T3-T4) (p=0.007) and the greater the BMI, the greater the severity of the CS (p<0.001). No statistically significant difference was found between the BMI bands in relation to the degree of satisfaction (p=0.644), nor when we compared the degree of satisfaction to the degree of CS (p=0.316).

CONCLUSIONS

The greater the BMI, the more severe the CS, but this did not correlate with the patients' level of satisfaction. Avoiding the resection of T2 sympathetic ganglia is also important in reducing the intensity of CS.
