Endoscopic clipping in video-assisted thoracoscopic sympathetic blockade for axillary hyperhidrosis. An analysis of 26 cases

Thoracic sympathectomy for the treatment of primary axillary hyperhidrosis: systematic review and proportional meta-analysis

INTRODUCTION

Primary hyperhidrosis is a disorder that involves excessive sweat production, which has a negative impact on the quality of life.

OBJECTIVE

To evaluate the effectiveness and safety of video-assisted thoracoscopic sympathectomy (VATS) for treating primary axillary hyperhidrosis (PAH) and determine which level of ganglion resection offers the best outcome.

METHOD

This was a systematic review and proportional meta-analysis of observational studies. The result was evaluated for satisfaction, control of symptoms, compensatory sweating and complications. A subgroup analysis was performed to compare the sympathetic trunk resection at high and low levels.

RESULTS

Thirteen studies were selected with a total of 1463 patients. The satisfaction rate was 92% (95% CI = 88-95%, I2=47.5%), the symptom control rate was 96% (95% CI = 93-99%, I2=48.2%), and the presence of compensatory sweating could not be assessed because of high heterogeneity among studies. The complications were rare.

CONCLUSION

This review demonstrated that thoracic sympathectomy by VATS is a viable and safe option for the treatment of PAH. There was no difference between high and lower levels of resection. However, the estimation of the effect is quite uncertain because the quality of evidence was extremely low.Key messagePure axillary hyperhidrosis has great potential to compromise quality of life.Surgery should be indicated only when clinical treatment fails.Thoracic sympathectomy by video-assisted thoracoscopy is a viable and safe option for the treatment of primary axillary hyperhidrosis.

Role of surgical thoracic sympathetic interruption in treatment of facial blushing: a systematic review

OBJECTIVES

This paper aims to review the evidence to support the effectiveness of sympathectomy as a treatment for facial blushing in terms of relief of facial blushing, patient satisfaction, recurrence of blushing, patients regretting treatment and its associated complications.

METHODS

A systematic search strategy was performed in Ovid-Medline, Embase, Cochrane library and NICE. Studies reporting outcomes of sympathetic interruption in the treatment of facial blushing were retrieved.

RESULTS

Nine studies met the inclusion criteria with 1369 patients included in the final analysis. The age range of patients was 8 to 74 years (from 7 studies) with 56% females. Mean follow up was 21 months in 8 studies (range 6 to 30 months). The pooled proportion of patients who had good relief of facial blushing was 78.30% (95% C.I. 58.20% - 98.39%). Complete satisfaction was reported in 84.02% (95% C.I. 71.71% - 96.33%). Compensatory sweating and gustatory sweating were the commonest complications occurring in 74.18% (95% C.I. 58.10% - 90.26%) and 24.42% (95% C.I. 12.22% - 36.61%) respectively. The estimated proportion of patients regretting surgery was 6.79% (C.I 2.08% 11.50%).

CONCLUSION

Sympathetic interruption at T2 or T2-3 ganglia appears to be an effective treatment for facial blushing. However, lack of randomized trials comparing sympathetic interruption with non-surgical methods of treatment and heterogeneity of included studies with respect to assessment of outcome measures preclude strong evidence and definitive recommendations.

Reversibility of Sympathectomy for Primary Hyperhidrosis

Endoscopic thoracic sympathectomy (ETS) is an effective treatment of primary hyperhidrosis of the face, upper extremities, and axillae. The major limitation is the side effect of compensatory sweating severe enough that patients request reversal in up to 10% of cases. When ETS is performed by cutting the sympathetic chain, reversal requires nerve grafting. However, for ETS done with clips, reversal is a simple thoracoscopic outpatient procedure of removing the clips. Subsequent reversal of the sympathectomy, ie, nerve regeneration, is successful in many cases. However, follow-up is short. Factors contributing to success rates require further study.

Robotic selective postganglionic thoracic sympathectomy for the treatment of hyperhidrosis

BACKGROUND

The surgical management of hyperhidrosis is controversial. Robotic surgical systems with their high-definition magnified 3-dimensional view and increased maneuverability in a confined space may facilitate the technique of selective sympathectomy (ramicotomy). We present a case series of patients undergoing selective postganglionic thoracic sympathectomy using robotic technology.

METHODS

This study is a case series analysis of patients who underwent selective postganglionic thoracic sympathectomy from July 2006 to November 2011. The operation was performed on a video-assisted thoracoscopic surgery (VATS) platform. The robot was used for pleural dissection and division of the postganglionic sympathetic fibers and the communicating rami. The success of sympathectomy was assessed by intraoperative temperature measurement of the ipsilateral upper extremity, patient interviews, and scoring of the symptomatic nature of hyperhidrosis based on the Hyperhidrosis Disease Severity Scale.

RESULTS

There were 110 sympathectomies performed in 55 patients (25 men, 30 women). Simultaneous bilateral sympathectomy was performed in all patients. Median age was 28 years (range, 16 to 65 years). There was no conversion to thoracotomy. Complications were minor and were seen in 5 of 55 patients (9%). There were no deaths. Median hospital stay was 1 day (range, 1 to 4 days). Of the 55 patients, 53 (96%) had sustained relief of their hyperhidrosis at a median follow-up of 24 months (range, 3 to 36 months), and compensatory sweating was seen in 4 patients (7.2%).

CONCLUSIONS

Robotic thoracoscopic selective sympathectomy is an effective, feasible, and safe procedure with excellent relief of hyperhidrosis and low rates of compensatory sweating and complications.

Selective sympathectomy for hyperhidrosis: technique of robotic transthoracic selective postganglionic efferent sympathectomy

Selective postganglionic efferent sympathectomy for hyperhidrosis is associated with excellent relief of hyperhidrosis and a low rate of compensatory hyperhidrosis. However, this technique can be difficult using conventional videoendoscopic techniques. We performed this technique using robotic technology in 55 patients. There was complete relief of hyperhidrosis in 53/55 (96%) patients, partial relief in 2/55 (4%) patients and a compensatory hyperhidrosis rate of 7%.

Compensatory hyperhidrosis following thoracic sympathectomy: a biophysical rationale

A side-effect of endoscopic thoracic sympathectomy (ETS) is compensatory hyperhidrosis (CH), characterized by excessive sweating from skin areas with intact sudomotor function. The physiological mechanism of CH is unknown, but may represent an augmented local sweat rate from skin areas with uninterrupted sympathetic innervation based on evaporative heat balance requirements. For a given combination of activity and climate, the same absolute amount of evaporation (if any) is needed to balance the rate of metabolic heat production both pre- and post-ETS. However, the rate of local sweating per unit of skin surface area with intact sudomotor activity must be greater post-ETS as evaporation must be derived from a smaller skin surface area. Under conditions with high evaporative requirements, greater degradations in sweating efficiency associated with an increased dripping of sweat should also occur post-ETS, further pronouncing the sweat rate required for heat balance. In conclusion, in addition to the potential role of psychological stimuli for increased sudomotor activity, the existence of CH post-ETS can be described by the interplay between fundamental thermoregulatory physiology and altered heat balance biophysics and does not require a postoperative alteration in physiological control.

Endoscopic thoracic sympathectomy for primary palmar hyperidrosis

BACKGROUND

Primary hyperhidrosis is a disorder that is characterized by excessive sweating in disproportion to that required for thermoregulation. In most cases, this is aggravated by emotional factors and by heat. Hyperhidrosis can be seen in the palms of the hands, armpits, soles of the feet and face. The principal characteristic of this disease is the intense discomfort of patients, which affects their social and professional life. Treatment modalities include topical application of aluminum chloride, iontophoresis, anticholinergics, botulinum toxin injection, liposuction, excision of sweat glands, and thoracic sympathectomy.

METHODS

Between January 1998 and August 2007, a prospective study of endoscopic thoracic sympathectomies for palmar hyperhidrosis was undertaken based on case histories and a prospective pre- and postoperative questionnaire survey. The sample comprised of 322 patients with a mean age of 24 years. At Apollo Hospital, New Delhi, India, bilateral video-assisted thoracoscopic T3 level sympathectomies were performed in all cases.

RESULTS

All patients had immediate cessation of palmar hyperhidrosis. The mean postoperative stay was 1.1 days. A questionnaire was completed based on their response to a telephone conversation or e-mail. A paired t test and Wilcoxon test was performed on these data and it showed significant improvement in quality of life. Compensatory sweating was found to be the most troublesome side effect for all patients. It was seen in 63% of the patients. This is similar to other reports of compensatory sweating; however, the figure decreases to 29% if we disregard the percentage of patients who reported only mild compensatory sweating.

CONCLUSION

In view of the low morbidity and zero mortality rate of this surgical technique, we recommend it as a method of treatment for palmar hyperhidrosis. Thoracic sympathectomy eliminates palmar hyperhidrosis with minimal recurrence (1% in our series) and produces a high rate of patient satisfaction.

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.

Sustained benefit lasting one year from T4 instead of T3-T4 sympathectomy for isolated axillary hyperhidrosis

INTRODUCTION

Level T4 video-assisted thoracoscopic sympathectomy proved superior to T3-T4 treatment for controlling axillary hyperhidrosis at the initial and six-month follow-ups of these patients.

OBJECTIVE

To compare the results of two levels of sympathectomy (T3-T4 vs. T4) for treating axillary sudoresis over one year of follow-up.

METHODS

Sixty-four patients with axillary hyperhidrosis were randomized to denervation of T3-T4 or T4 alone and followed prospectively. All patients were examined preoperatively and were followed postoperatively for one year. Axillary hyperhidrosis treatment was evaluated, along with the presence, location, and severity of compensatory hyperhidrosis and self-reported quality of life.

RESULTS

According to patient reports after one year, all cases of axillary hyperhidrosis were successfully treated by surgery. There were no instances of treatment failure. After six months, compensatory hyperhidrosis was present in 27 patients of the T3-T4 group (87.1%) and in 16 patients of the T4 group (48.5%). After one year, all T3-T4 patients experienced some degree of compensatory hyperhidrosis, compared to only 14 patients in the T4 group (42.4%). In addition, compensatory hyperhidrosis was less severe in the T4 patients (p < 0.01). Quality of life was poor before surgery, and it improved in both groups at six months and one year of follow-up (p = 0.002). There were no cases of mortality, no significant postoperative complications, and no need for conversion to thoracotomy in either group.

CONCLUSION

Both techniques were effective for treating axillary hyperhidrosis, but the T4 group showed milder compensatory hyperhidrosis and greater patient satisfaction at the one-year follow-up.

Excision of sympathetic ganglia and the rami communicantes with histological confirmation offers better early and late outcomes in Video assisted thoracoscopic sympathectomy

BACKGROUND

Video-Assisted Thoracoscopic Sympathectomy (VATS) is an established minimally invasive procedure for thoracic sympathetic blockade in patients with hyperhidrosis, facial flushing and intractable angina. Various techniques using clips, diathermy and excision are used to perform sympathectomy. We present our technique of excision of the sympathetic chain with histological proof and the analysis of the early and late outcomes.

METHODS

We evaluated 200 procedures in 100 consecutive patients, who underwent Video Assisted Thoracoscopic Sympathectomy by a single surgeon in our centre between September 1996 to March 2007. All patients had maximum medical therapy prior to surgery and were divided into 3 groups based on indications, Group 1(hyperhidrosis: 48 patients), Group 2 (facial flushing: 26 patients) and Group 3(intractable angina: 26 patients). The demography and severity of symptoms for each group were analysed. The endpoints were success rate, 30 day mortality, complications and patient's satisfaction.

RESULTS

99 patients had bilateral VATS sympathectomy and 1 had unilateral sympathectomy. The conversion rate to open was 1(1%). All patients had successful removal of ganglia proven histologically with no perioperative mortality in our series. The complications included pneumothorax (5%), acute coronary syndrome (2%), transient Horner's syndrome (1%), transient paraesthesia (1%), wound infection (4%), compensatory hyperhidrosis (18%), residual flushing (3%) and wound pain (5%). There were five late deaths in the intractable angina group at a mean follow up of 36.7 months. Overall success rates of abolishing the symptoms were 96.3%, 87.5% and 95.2% for Group 1, 2 and 3 respectively.

CONCLUSION

Excision of the sympathetic chain with histological confirmation during VATS sympathectomy is a safe and effective method in treating hyperhidrosis, facial flushing and intractable angina with good long term results and satisfaction.

Video-assisted thoracic sympathectomy in the treatment of primary hyperhidrosis: a retrospective study of 521 cases comparing different levels of ablation

OBJECTIVE

To compare different levels of ablation in terms of the degree of patient satisfaction and extent of postoperative reflex sweating in sympathectomized patients.

METHODS

A retrospective study involving 521 patients with primary hyperhidrosis, submitted to thoracic sympathectomy at the Monte Sinai Hospital and University Hospital of the Federal University of Juiz de Fora, from January of 2001 to December 2005. All patients were submitted to thermal ablation of the sympathetic stem and were divided into three groups: up to T2 (group I, n = 162); up to T3 (group II, n = 65); and up to T4 (group III, n = 294).

RESULTS

Optimal postoperative control of palmar/axillary hyperhidrosis was achieved in, respectively, 94/82% of the patients of group I, 89/89% of those in group II and 80/80% of those in group III. Postoperative reflex sweating was observed in 67% of the patients in groups I and II, compared with 61.29% of those in group III. Severe reflex sweating occurred in 32% of the group I patients, 9% of the group II patients and 4% of the group III patients.

CONCLUSION

Sympathectomy provided excellent patient satisfaction and a low incidence of complications. There was no significant difference between the levels of ablation in terms of reflex sweating, although the intensity of this complication decreased when lower levels of blockage, principally at the T4 level, were employed.

Thoracoscopic Sympathectomy for Primary Palmar Hyperhidrosis: Resection Versus Transection—A Prospective Trial

Upper dorsal sympathectomy is the only successful therapeutic method for idiopathic palmar hyperhidrosis (IPHH). However, the techniques for sympathetic ablation are still debated. The aim of this study was to compare prospectively two accepted methods for endoscopic sympathetic ablation: resection of T2-T3 ganglia versus transection of the chain over the second to fourth ribs. During the period September 2000 to June 2002, a total of 32 patients with IPHH were operated on. Operations were performed under general anesthesia through two 5-mm trocars using electrocautery. Resection was done on one side and transection on the other, with both sides being addressed during the same operation. The sides of resection/transection were alternated at each operation. There were 14 men and 18 women aged 18.8 +/- 4.7 years. The mean operating times for sympathectomy were 12.0 +/- 3.1 minutes for resection and 6.6 +/- 1.9 minutes for transection (p = 1.38). All patients were examined at 2 weeks postoperatively and again at 1 month. During November-December 2005, patients were approached by telephone questionnaire, the mean follow-up period being 4.3 +/- 0.9 years. Altogether, 26 of the 32 patients could be located (15 women, 11 men). There was no significant difference with regards to perioperative complications, immediate or long-term pain. All but two hands were warm and dry 1 month after operation and remained so at follow-up. The exceptions included one hand with recurrent hyperhidrosis after 1.5 years and one that became less dry and cold at 3 years. Both were on the transected sides. Our results suggest that sympathetic resection may achieve slightly better long-term results than transection in patients with IPHH. Large-scale prospective studies are needed to confirm these results.

Axillary hyperhidrosis: T3/T4 versus T4 thoracic sympathectomy in a series of 276 cases

BACKGROUND

Different techniques of video-assisted thoracic sympathectomy have been suggested to control the symptoms of axillary hyperhidrosis. We compared the results using two different levels of ganglion resection for treating axillary hyperhidrosis: T3/T4 vs. T4.

MATERIALS AND METHODS

From a group of 1119 patients operated on between July 2000 and January 2005, 276 patients with axillary hyperhidrosis were studied. The mean age was 26 (range, 13-54 years) and 61.6% were female. Of these patients, 216 (78.3%) were treated with thermal ablation of T3/T4 and 60 (21.7%) with thermal ablation of T4 alone. The procedures were bilateral and simultaneous, using two 5.5-mm trocars and 30-degree optical systems, under general anesthesia in all cases.

RESULTS

There was no mortality and no important postoperative complications or need to convert to thoracotomy in either group. The mean follow-up in the T4 group was 11 months (range, 2-23 months) and in the T3/T4 group mean follow-up was 24 months (range, 13-54 months). The immediate therapeutic success rate was 100% in both groups. There were recurrences in 7 (2.5%) patients, all from the T3/T4 group. The satisfaction rate was higher and more stable in the T4 group and compensatory sweating was lower in the T4 group.

CONCLUSION

Both techniques proved effective for controlling the axillary symptoms. Group T4 presented a higher satisfaction rate, lower recurrence rate, and lower severity of compensatory sweating.

A randomized trial of T3-T4 versus T4 sympathectomy for isolated axillary hyperhidrosis

INTRODUCTION

Video-assisted thoracic sympathectomy (VATS) is one minimally invasive definitive treatment for axillary hyperhidrosis. Different techniques exist for controlling axillary sudoresis, but they are temporary and have high cost. This study was conducted to compare the initial results from sympathectomy using two distinct levels for treating axillary sudoresis: T3-T4 vs T4.

METHODS

Sixty-two patients with axillary hyperhidrosis were prospectively randomized for denervation of T3-T4 or T4 alone. All patients were examined preoperatively and were followed-up at 1 and 6 months postoperatively. Evaluated were the axillary hyperhidrosis treatment, the presence, location, and severity of compensatory hyperhidrosis, and the quality of life.

RESULTS

All the patients said that their axillary hyperhidrosis was successfully treated by the surgery after 6 months. There was no treatment failure. Compensatory hyperhidrosis was present in 29 patients (90.6%) of the T3-T4 group and in 17 T4 patients (56.7%) after 1 month. After 6 months, all the T3-T4 patients presented some degree of compensatory hyperhidrosis vs 13 T4 patients (43.3%). The severity of the compensatory hyperhidrosis was also lower in the T4 patients (P < . 01). The quality of life was poor in both groups before the surgery, and was equally improved in both groups after 1 and 6 months of follow-up. There were no deaths or significant postoperative complications nor a need for conversion to thoracotomy.

CONCLUSION

Both techniques are effective for treating axillary hyperhidrosis, but the T4 group presented milder compensatory hyperhidrosis and had a greater satisfaction rate.

Endoscopic Thoracic Sympathectomy for Severe Hyperhidrosis: Impact of Restrictive Denervation on Compensatory Sweating

BACKGROUND

Compensatory sweating is noted frequently after sympathectomy and may be difficult to control in some patients. This prospective trial was projected to measure the impact of limited denervation on compensatory sweating while performing endoscopic thoracic sympathectomy.

METHODS

One hundred seventy-eight patients (127 female and 51 male) with severe primary hyperhidrosis unsuccessfully treated by conservative means entered the study. Group A was treated with sympathectomy from T2 to T4. In group B sympathectomy was performed from T3 to T5. Physical condition was measured after 1, 6, and 24 months by means of the SF-36 Health Survey Test.

RESULTS

Evaluation rate was 94.9%. Horner's syndrome was not detected, recurrence rate was 0.6%, and rate of persistent pneumothorax was 2.3%. Compensatory sweating was reported with 17.1% in group A and diminished to 4.9% in group B. Gustatory sweating was comparable in both groups (4.3% versus 4.9%). Satisfaction rate was 97% in patients with palmar hyperhidrosis, 95% for axillary hyperhidrosis, and 87% for facial hyperhidrosis. Discomfort originating from compensatory sweating was less than symptoms from primary hyperhidrosis 24 months after endoscopic thoracic sympathectomy in more than 90%. Only 7.1% of the entire group was not satisfied.

CONCLUSIONS

Our study demonstrates that limiting denervation beyond T2 ganglion offers good clinical results in axillary as well as palmar hyperhidrosis and may reduce the risk for compensatory sweating. In women, reduction was as high as 75% and in men, near 50%. Our impression is that severe compensatory sweating and the majority of stellate ganglion lesions occur as a result of starting sympathectomy at level T2.

Long-Term Results of Thoracoscopic Sympathectomy for Hyperhidrosis

BACKGROUND

Thoracoscopic sympathectomy is now the reference treatment for severe palmar hyperhidrosis, but this is offset by the occurrence of compensatory sweating. It has been studied in this series to improve the indications and information given to patients.

METHODS

A retrospective review of 124 patients who were previously afflicted with bilateral thoracoscopic sympathectomy 6 years earlier was conducted. Patients were interviewed by postal questionnaire regarding the results and side effects.

RESULTS

The series consisted of 89 females (72%) and 35 males and the mean age was 28 years. The main indication was palmo-plantar hyperhidrosis (34%). The mean operating time was 36 minutes and there were no intraoperative complications. Postoperative pneumothorax occurred in 9 patients and 3 patients required a chest drain. The hospital stay was 36 hours for 87.6% of the patients. Postoperative pain occurred in 78% of the patients. Neurologic complications (Horner syndrome, radial paralysis, and dysesthesia of the arm) occurred in 3 patients and disappeared after 2-6 months. Two patients required single-side reoperation because of failure with the first intervention. Eighty-nine replies to questionnaires were received (72%). The results for hands were favorable in 98% and in 63% for axillae. Compensatory sweating occurred in 87% of the patients (serious in 36% and incapacitating in 6%). Despite this 90% of the patients were satisfied or very satisfied.

CONCLUSIONS

This study confirms that thoracoscopic sympathectomy is a suitable method of treatment for severe palmar hyperhidrosis but emphasizes the need to offer the patient more informative information, especially regarding compensatory sweating which seems inescapable.

[Thoracoscopic sympathectomy for palmar hyperhidrosis. Immediate results and postoperative quality of life]

OBJECTIVE

Primary palmar hyperhidrosis is a socially and occupationally debilitating disorder characterized by excessive sweating. The purpose of this study was to evaluate the results, complications, and degree of satisfaction among patients who underwent video-assisted bilateral thoracoscopic sympathectomy of the second and third ganglia (T2-T3) to treat primary palmar hyperhidrosis at the Department of General and Thoracic Surgery of the Hospital Universitario Virgen Macarena in Seville, Spain.

MATERIAL AND METHOD

A study of 226 thoracoscopic sympathectomies was undertaken based on case histories and a prospective pre- and postoperative questionnaire survey. The sample was composed of 113 patients (47 males and 66 females), ranging in age from 14 to 50 years, with primary palmar and axillary hyperhidrosis, in some cases severe. Bilateral video-assisted thoracoscopic T2-T3 sympathectomy was performed under general anesthesia in all cases. Follow up included a questionnaire on pre- and postoperative quality of life and degree of satisfaction. Descriptive statistics on the surgical procedure, quality of life, and postoperative changes were compiled and frequency analyzed. A nonparametric Wilcoxon test for paired variables was performed to contrast significant differences between pre- and postoperative quality of life related to hyperhidrosis and its complications.

RESULTS

The therapeutic success rate was 100%. Complications were seen in 14.2% of the cases and included hemothorax in two, hemopneumothorax in three, pleural hemorrhage in two, and minimal apical airspace in nine. Of the 106 patients who were monitored over a period of 6 to 12 months through follow-up interviews and questionnaires, 67% developed compensatory sweating, 95% reported improvement in quality of life, and 4% experienced no change in quality of life, mainly because of the emergence of compensatory sweating. Of the patients interviewed, 97.2% said that they would undergo the operation again.

CONCLUSION

Video-assisted thoracoscopic sympathectomy for the treatment of primary palmar hyperhidrosis is effective, with low rates of morbidity and no mortality. Despite the appearance of postoperative changes such as compensatory sweating, patient satisfaction with the procedure is high and their quality of life improves.

Limited endoscopic thoracic sympathetic block for hyperhidrosis of the upper limb: reduction of compensatory sweating by clipping T4

BACKGROUND

Endoscopic thoracic sympathicotomy of T2 to T4 (ETS 2-4) has evolved into an effective treatment for severe hyperhidrosis of the upper limb. Complications such as bleeding or Horner's syndrome are rare, but side effects such as compensatory and gustatory sweating occur in 30-50% of patients. Following the Lin-Telaranta classification, we aimed to reduce these side-effects by clipping T4 solely [endoscopic thoracic sympathetic block (ESB 4)]. We present our experience and clinical results using this method, with emphasis on patients' quality of life.

METHODS

A total of 176 procedures (91 patients) were carried out in the ETS 2-4 group and 103 procedures (53 patients) in the ESB 4 group: 60.4 and 43.4% had palmar hyperhidrosis, 8.8 and 5.7% had isolated axillary, and 30.8 and 50.9% had combined manifestations, respectively. Follow-up was 22.1 months (obtained from 79.1% of patients) for the ETS 2-4 group and 7.5 months for the ESB 4 group (obtained from 88.7%).

RESULTS

The success rate was similar for both groups: 87.9 and 64.5% had completely dry limbs, 9.9 and 35.5% ( p < 0.0002) were nearly dry, and 2.1 and 0% remained wet. (ETS 2-4 vs ESB 4). Although the armpits remained slightly humid in more patients in the ESB 4 group, 100% stated full satisfaction. Complications did not differ significantly. However, compensatory sweating (55.6 vs 8.5%, p = 0.0002) and gustatory sweating (33.3 vs 2.1%, p = 0.0019) were markedly reduced (ETS 2-4 vs ESB 4). Quality of life was assessed by a hyperhidrosis index, which significantly improved in most patients.

CONCLUSIONS

ETS 2-4 and ESB 4 have similar success rates in the treatment of upper limb hyperhidrosis. The major side effects of compensatory and gustatory sweating were effectively reduced by the limited method of clipping T4, and patients' satisfaction and improvement in quality of life were remarkable.
