Uniportal Endoscopic Thoracic Sympathectomy for Treatment of Palmar and Axillary Hyperhidrosis: Analysis of 2000 Cases

Risk Factors Affecting the Outcomes of CT-Guided Radiofrequency Thermocoagulation of the T3 Sympathetic Nerve in the Treatment of Craniofacial Hyperhidrosis

Background

Current studies mostly suggest that hyperhidrosis is caused by relative sympathetic hyperactivity. Sympathetic radiofrequency thermocoagulation is widely used in clinics. Previous studies have demonstrated that surgery at T3 is effective and safe compared with higher levels, so craniofacial hyperhidrosis in our hospital is selected to be treated at T3. However, some patients pursue repeat medical treatment due to an increase in hyperhidrosis at the original site after surgery. Previous studies have demonstrated the significance of Perfusion index (PI) value in the recurrence of palmar hyperhidrosis, but there is no relevant study on craniofacial hyperhidrosis.

Methods

Clinical data from patients with craniofacial hyperhidrosis, who underwent T3 sympathetic radiofrequency thermocoagulation at Jiaxing First Hospital (Jiaxing, China) between January 1, 2018 and December 31, 2021, were analyzed. Recurrence in patients 1 year after surgery was recorded through a case search and telephone follow-up system that registered patient information. Clinical data were analyzed using binary logistic regression analysis to investigate risk factors associated with recurrence in patients with craniofacial hyperhidrosis 1 year after surgery.

Results

Of 83 patients included in the present study, 34 (40%) experienced increased craniofacial sweating 1 year after surgery. Results of univariate logistic regression analysis revealed that computed tomography (CT) scan count, increase in pulse index (PI) at the fingertips, and differences in forehead temperature were potential risk factors for postoperative recurrence in patients with craniofacial hyperhidrosis (p<0.2), and the results were consistent on both sides. Three potential risk factors were included in the multivariate logistic regression analysis and results revealed that the risk for recurrence was reduced by 48% (left side) and 67% (right side) for every 1 unit increase in PI value.

Conclusion

A small increase in PI was an independent risk factor for recurrence of hyperhidrosis in patients with craniofacial hyperhidrosis after undergoing T3 sympathetic radiofrequency thermocoagulation.

The success rate and associated risk factors of CT-guided percutaneous radiofrequency sympathectomy in the treatment of primary hyperhidrosis: A retrospective observational trial

PURPOSE

The aim of this study was to investigate the success rate of surgical technique and associated risk factors based on the follow-up of patients who underwent CT-guided percutaneous radiofrequency sympathectomy (RFS) to treat primary hyperhidrosis (PH).

METHODS

370 patients who underwent RFS for PH treatment between January 2018 and April 2022 were enrolled. Patients responded to a questionnaire and telephone follow-up on the effects of treatment and their electronic medical records and imaging findings were reviewed. Logistic regression was performed to identify risk factors related to the success rate of surgical technique.

RESULTS

A temperature difference ≥2 °C before and after procedure was defined as a successful surgical technique. Among the 370 patients (740 sides), 637 sides had successful RFS, and the technical success rate was 86.1 %. Immediately after procedure, 636 sides (85.9 %) were completely dry, 64 (8.7 %) were partially dry, and 40 (5.4 %) were still wet. During the longest follow-up period (54 months), 103 patients relapsed. The median hyperhidrosis disease severity scale score on both sides decreased from 4 to 1 after RFS. According to logistic regression analysis, only the pre-post pulse index was associated with the success rate of surgical technique (odds ratio, 1.14; 95 % confidence interval, 1.06-1.23; p = 0.0004).

CONCLUSIONS

We observed that the immediate efficiency and success rate of surgical technique after RFS for PH treatment were relatively high, although there is a possibility of recurrence in the long term. In general, RFS is a safe and effective procedure for alleviating the symptoms of patients with hyperhidrosis.

Development and Validation of a Nomogram to Predict Recurrence of Primary Hyperhidrosis after CT-guided Percutaneous Radiofrequency Sympathectomy

PURPOSE

To evaluate the recurrence rate of primary hyperhidrosis (PH) after computed tomography (CT)-guided radiofrequency sympathectomy (RFS) and identify risk factors associated with recurrence.

MATERIALS AND METHODS

A total of 290 patients with PH who underwent CT-guided RFS were included in this retrospective cohort study. The electronic medical record was reviewed for patients' information and procedural parameters. Follow-ups were conducted for recurrence rate, and Hyperhidrosis Disease Severity Scale was used to assess presence or absence of recurrence. Stepwise regression and the least absolute shrinkage and selection operator regression algorithms were used for feature selection.

RESULTS

The recurrence rate 1 year after procedure was 17.6%. Male (hazard ratio [HR], 2.35; 95% confidence interval [CI], 1.08-5.15), low postoperative palm or foot temperature (HR, 0.77; 95% CI, 0.60-0.98), high postoperative heart rate (HR, 1.06; 95% CI, 1.02-1.10), low preoperative and postoperative hospital anxiety and depression score difference (HR, 0.59; 95% CI, 0.43-0.80), and the absence of compensatory hyperhidrosis immediately after procedure (HR, 0.46; 95% CI, 0.22-0.98) were established as independent factors affecting prognosis. A nomogram was built accordingly. The C indices of the training and testing sets were 0.773 and 0.659, respectively.

CONCLUSIONS

Follow-up results showed that the recurrence rate of PH treated with CT-guided RFS was low. This study constructed and validated a nomogram to predict the recurrence of PH 1 year after CT-guided RFS, which is convenient for interventionalists to evaluate accurately the prognosis of patients postoperatively and to identify high-risk patients who need more active treatment.

[Hyperhidrosis: treatment, results, problems]

OBJECTIVE

To analyze the results of thoracic sympathectomy for hyperhidrosis.

MATERIAL AND METHODS

The study included 166 patients aged from 15-51 years. There were 118 women and 48 men. Isolated palmar hyperhidrosis was observed in 46 patients, axillary - 46 patients, palmar-axillary - 74 cases. Video-assisted thoracic bilateral sympathectomy was performed. In patients with palmar hyperhidrosis, sympathetic chain was transected between the ribs II and III, axillary and palmar-axillary hyperhidrosis - between the ribs III and IV.

RESULTS

Intraoperative injury of intercostal artery occurred in 1 case. Cautery was effective. Postoperative complications occurred in 4 (2.4%) patients (pneumothorax followed by drainage for up to 2-3 days). Symptoms of hyperhidrosis disappeared early after surgery in all cases. Long-term results were followed in 47 patients. Persistent positive effect and patient satisfaction with postoperative outcome were noted in 44 (93.6%) cases. Recurrences occurred in 2 patients with palmar hyperhidrosis and 1 patient with axillary hyperhidrosis for the period from 2 weeks to 6 months. Compensatory sweating developed in 26 (55.3%) patients (within several weeks up to 6 months). Mild compensatory sweating occurred in 17 patients, moderate - 8 patients, severe - 1 patient. Compensatory sweating was more common in patients with axillary and palmar-axillary hyperhidrosis compared to those with isolated palmar hyperhidrosis (p<0.05). We found no significant difference in the incidence of compensatory sweating depending on the level of sympathetic chain intersection (p>0.05).

CONCLUSION

An effectiveness of thoracic sympathectomy for hyperhidrosis is obvious. Compensatory sweating is the main undesirable consequence of this surgery. Prediction and prevention of compensatory sweating are not possible. It is imperative to warn the patient about possible compensatory sweating.

Selective block of grey communicantes in upper thoracic sympathectomy. A feasibility study on human cadaveric specimens

Background: Sympathetic chain interruption is the gold standard treatment for essential hyperhidrosis. Postoperative compensatory hyperhidrosis, the main reason for patients' dissatisfaction, is reduced by selectively lesioning white and grey rami communicantes (ramicotomy).Objective: To develop an endoscopic surgical technique that interrupts only T₃ and T₄ grey rami communicantes to minimize compensatory hyperhidrosis.Material and Methods: T₃ and T₄ grey rami communicantes ramicotomy in fifteen cold-preserved cadavers through a uniportal axillary endoscopic approach. The sympathetic chain, its ganglia, and white rami communicantes were left intact. On opening the chest, the sympathetic chain, rami communicantes and ganglia were dissected, photographed, measured and excised for histological examination.Results: Dissecting the grey rami communicantes is feasible as they consistently lie between the intercostal nerve and the homonymous sympathetic ganglion. At some levels, Kuntz nerves, as well as more than one grey ramus communicans, can be found. White rami communicantes are more medial, therefore damaging them can be avoided. Intercostal veins can be obstructive, but these can be controlled via coagulation or clipping if necessary.Conclusion: Uniportal endoscopic selective excision of the T₃ and T₄ grey rami communicantes is feasible without damaging the white rami communicantes, the sympathetic chain or its ganglia. Clipping the grey rami communicantes is technically possible but not reliable due to their thin diameter. This study confirms that T₃ and T₄ grey rami sympathetic block is technically feasible. Its application might reduce compensatory hyperhidrosis, but clinical studies are needed.

[Outpatient thoracic surgery: Evolution of the indications, current applications and limits]

The objectives of outpatient surgery are to reduce the risks connected to hospitalization, to improve postoperative recovery and to decrease the health costs. Few studies have been performed in the field of thoracic surgery and there remains great scope for progress in outpatient lung surgery. The purpose of this article is to present a revue of the current situation and the prospects for the development of out patient thoracic surgery.

Uniportal video-assisted thoracic surgery: the lesser invasive thoracic surgery

OBJECTIVES

We evaluated whether single-port video-assisted thoracic surgery is feasible without compromising outcomes, and whether the technique could be reproduced by a trainee.

METHODS

In a 6-month period, 37 operations were performed by single-port video-assisted thoracic surgery. Of the 37 patients, 27 (73%) were male and the mean age was 45.1 ± 21 years. Twenty-three (62%) were operated on by consultants and 14 (38%) by trainees. The procedures included 19 (51.3%) operations for treatment of pneumothoraces, 8 (21.6%) metastasectomies, 7 (18.9%) lung biopsies, 2 (5.4%) empyema débridements, and 1 (2.7%) pleuropericardial window.

RESULTS

Mean operative time was 51.8 ± 14.7 min. Patient-controlled analgesia infusion was used for 1.3 ± 1 days. Three (8.1%) patients needed an operative reintervention, but there was no intensive treatment unit admission or hospital mortality. Mean postoperative hospital stay was 3.3 ± 2.7 days. On follow-up, all patients had a tissue diagnosis and all lung nodules were R0 resections. Patients operated on by consultants and trainees had similar preoperative profiles and postoperative outcomes, except that those operated on by trainees used patient-controlled analgesia significantly longer (1.8 ± 1.48 vs. 1 ± 0.48 days; p = 0.03).

CONCLUSION

Single-port video-assisted thoracic surgery can be performed and reproduced well without compromising outcomes. It is considered aesthetically better and may reduce analgesic requirements, but it might not reduce hospital stay.

Duration of efficacy increases with the repetition of botulinum toxin A injections in primary axillary hyperhidrosis: a study in 83 patients

BACKGROUND

Intradermal injections of botulinum toxin are effective but transitory in primary axillary hyperhidrosis. These injections are repeated when the symptoms recur. The reported duration of efficacy is variable, from 2 to 24 months, but it is unknown how the duration of efficacy changes when injections are repeated.

OBJECTIVE

In this retrospective study, we aimed to evaluate changes in the duration of efficacy of botulinum toxin injections (Dysport, Ipsen, Boulogne-Billancourt, France) with the repetition of injections in patients with axillary hyperhidrosis.

METHODS

From May 2001 to April 2012 inclusive, 83 patients were treated with a dose of 125 U per underarm. We compared the duration of effect of the first and last toxin injections.

RESULTS

The median duration of efficacy for the first injection was 5.5 months, whereas that for the last injection was 8.5 months. The difference between these 2 durations is statistically significant (P = .0002).

LIMITATIONS

Although retrospective and based on the declarative, this work is the first to our knowledge to highlight this benefit of treatment and to evaluate botulinum toxin over such a long period (11 years).

CONCLUSION

There appears to be an increase in the duration of efficacy of botulinum toxin A injections with the repetition of injections in patients with primary axillary hyperhidrosis. The reasons for this effect may be linked to the mechanism of action of botulinum toxin, and may improve our understanding of its pharmacologic effects.

Technical difficulties and complications of sympathectomy in the treatment of hyperhidrosis: an analysis of 1731 cases

BACKGROUND

The aim of this study was to ascertain the technical difficulties and complications of video-assisted thoracic sympathectomy (VTAS) in the treatment of hyperhidrosis in a large group of patients.

METHODS

Between October 1995 and February 2008, 1731 patients with palmar, axillary, or craniofacial hyperhidrosis, who were treated using bilateral VTAS, were studied. We assessed the technical difficulties, early and late complications, and the approaches that were used to resolve them.

RESULTS

Therapeutic success was achieved in 91% of the cases as evidenced by anhidrosis. The most common and severe technical difficulty during the procedure was pleural adhesions in 116 cases (6.7%); azygos lobes were seen in 7 patients (0.4%) and apical blebs in 3 patients (0.2%). The most frequent postoperative immediate complication was postoperative pain in 1685 (97.4%) patients; pneumothorax with chest drainage was seen in 60 cases (3.5%), neurologic disorders involving the upper limbs in 36 cases (2.1%), Horner's syndrome in 11 cases (0.9%), significant bleeding in 8 cases (0.4%), and 1 patient had extensive subcutaneous emphysema. The most frequent late complication was compensatory hyperhidrosis, which occurred in 1531 cases (88.4%). Although 27.2% of the patients reported severe compensatory hyperhidrosis, only 2.5% expressed regret for undergoing surgery. Gustatory sweating occurred in 334 patients (19.3%). No deaths occurred in this series.

CONCLUSIONS

VTAS is safe and has shown good results. The major complication is compensatory hyperhidrosis and, when severe, the patient may express regret for undergoing surgery. Improvements in instrumentation, adequate training, and careful patient selection may help to reduce the number of drawbacks associated with VTAS.

Quality of life before surgery is a predictive factor for satisfaction among patients undergoing sympathectomy to treat hyperhidrosis

PURPOSE

The objective of this study was to evaluate the postoperative quality of life (QOL) experienced among a group of 1167 patients who underwent video-assisted thoracoscopic sympathectomy (VATS) to treat primary hyperhidrosis, as compared with the presurgical QOL.

METHODS

Between February 2002 and June 2007, 1167 patients who had undergone VATS were surveyed. The majority had presented with palmar hyperhidrosis (794 patients; 68%), while 340 (29%) had presented with axillary hyperhidrosis. Based on data obtained from the QOL protocol applied to all of the patients preoperatively, the patients were divided into two groups according to the level of their QOL: group 1 consisted of 312 patients (27%) with poor QOL and group 2 of 855 patients (73%) with very poor QOL. The same protocol was applied postoperatively, and five different levels of satisfaction were obtained. The same parameters were evaluated for both the palmar and the axillary hyperhidrosis subgroups.

RESULTS

The patients with very poor QOL had much better results in terms of improvement in QOL than did those with poor QOL (P < .05). The same result was observed for both the palmar and axillary hyperhidrosis subgroups (P < .05).

CONCLUSION

The worse the preoperative QOL among patients undergoing sympathectomy to treat primary hyperhidrosis is, the better the postoperative improvement in QOL will be.

Comparison of ultrasonic scalpel to electrocautery in patients undergoing endoscopic thoracic sympathectomy

BACKGROUND

Sympathectomy is an effective treatment for hyperhidrosis. The ultrasonic scalpel and electrocautery have been used for the procedure, but the use of the ultrasonic scalpel has been promoted as superior to that of electrocautery. This study explored whether a reusable electrocautery probe was equally as effective and safe as the ultrasonic scalpel for sympathectomy.

METHODS

We retrospectively analyzed 140 consecutive patients. The ultrasonic scalpel (HDH 05, Ethicon Endo-Surgery, Cincinnati, OH) was used in 70 patients (group 1) and a reusable 5-mm cautery hook (Edlo, Canoas, Brazil) was used in 70 patients (group 2). End points were improvement in symptoms (% improvement score), length of stay, return to work, and complications. Data were analyzed using two-tailed t test and the chi(2) (p = 0.05 was significant). Data are mean +/- standard deviation.

RESULTS

Follow-up was 27.2 +/- 8.4 months. Groups were similar in demographics, disease site, and level of sympathectomy. There was no significant difference in improvement score by site. The feet had the least improvement score (36.5% +/- 32.3%), and the hands the highest improvement score (97.0% +/- 11.3%). Length of stay was similar, 11.4 +/- 5.9 (group 1) vs 10.1 +/- 5.4 hours (group 2). Return to work in group 1 was 4.8 +/- 2.7 vs 5.7 +/- 3.6 days (p = 0.09). Group 1 had 14 complications and group 2 had 7 (p = 0.16).

CONCLUSIONS

We could not demonstrate a clear advantage in the use of the ultrasonic scalpel.

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

Sympathectomy (ETS) is an effective treatment for hyperhidrosis (HH), but compensatory hyperhidrosis (CH) is a common side effect. We reviewed our experience with 200 patients. Two hundred patients were retrospectively analyzed. Patients completed a questionnaire regarding their postoperative symptoms [% improvement score (IS), CH score], and their level of dissatisfaction, which was assessed as a function of regretting the choice to undergo ETS. Significance set at P< or =0.05. There were 123 (61.5%) females. Mean age was 28.2+/-7.4. Follow-up (mo) was 20.9+/-12.1. One ganglion was transected in 112 (56%) patients (G1), and more than one in 88 (G2). Overall, 157 (78.5%) patients had CH, 88 (74.1%) patients in G1 and 74 (84.1%) in G2, P=0.06. Patients in G2 had a higher CH score (4.1+/-2.7 versus 3.0+/-2.5, P<0.01), and a higher number of patients regretting surgery (11.4% versus 3.6%, P=0.05). Multivariate analysis showed age, high CH score, and surgery on T2 as independent predictors of patient's dissatisfaction (P<0.05). Patients with more than one ganglion transected demonstrate a trend toward a higher incidence of CH, a significantly higher CH score, and are more dissatisfied with ETS. Age, surgery on T2, and high CH score are independent predictors of patient's dissatisfaction.

IMPACT OF COMPENSATORY HYPERHIDROSIS ON PATIENT SATISFACTION AFTER ENDOSCOPIC THORACIC SYMPATHECTOMY

OBJECTIVE

Endoscopic thoracic sympathectomy (ETS) remains the definitive treatment for primary focal hyperhidrosis. Compensatory hyperhidrosis (CH) is a significant drawback of ETS. We sought to identify the predictors for the development of severe CH after ETS, its anatomic locations, and its frequency of occurrence, and we analyzed the impact of CH on patient satisfaction with ETS.

METHODS

Bilateral ETS for primary focal hyperhidrosis was performed in 220 patients, and a retrospective chart review was conducted. Follow-up evaluation was conducted using a telephone questionnaire, and 73% of all patients were contacted. Patients' responses regarding CH and their level of satisfaction after ETS were analyzed. Statistical analysis was performed using SPSS software (Version 14.0; SPSS, Inc., Chicago, IL). A P value of &lt;0.05 was considered statistically significant.

RESULTS

Some degree of CH developed in 94% of patients. The number of levels treated was not related to the occurrence of severe CH. Isolated T3 ganglionectomy led to a significantly lower incidence of severe CH, when compared with all other levels (P &lt; 0.03). Ninety percent of patients were satisfied with the procedure. The development of severe CH, as opposed to mild or moderate CH, significantly correlated with a lower satisfaction rate (P = 0.003).

CONCLUSION

CH is common after ETS procedures, and the occurrence of severe, but not mild or moderate, CH is a major source of dissatisfaction after ETS. The overall occurrence of severe CH is reduced after T3 ganglionectomy as opposed to ganglionectomies performed at all other levels. The level of satisfaction with ETS is high.

Thoracoscopic and anatomic landmarks of Kuntz's nerve: implications for sympathetic surgery

BACKGROUND

Kuntz's nerves (KN) have been blamed for surgical failures of endothoracic sympathectomy. The prevalence of these fibers, however, varies between the surgical (about 10%) and anatomic literature (about 80%). This clinically orientated cadaveric study was conducted to explain this discrepancy, to reveal possible reasons for the low thoracoscopic detection rate, and to define anatomic structures as possible landmarks of KNs.

METHODS

Video-assisted thoracoscopy was performed in 33 thoracic cavities of fresh human cadavers within 48 hours postmortem, followed by anatomic dissection of the first intercostal space. Kuntz's nerves and concomitant blood vessels were of special interest. Statistical analysis included frequencies and chi(2) tests.

RESULTS

Kuntz's nerves were identified in 12.1% by thoracoscopy, whereas anatomic dissection revealed KNs in 66.7% (p = 0.003). Subpleural veins (mean diameter, 2.2 +/- 0.9 mm) parallel to KNs were found in 81.8%. No collateral arteries were identified. Diameters of KNs were 1.4 +/- 0.7 mm; distances between the first thoracic ganglion and the middle of KNs were 9.7 +/- 3.0 mm. Thoracoscopic recognition of these Kuntz veins was higher than that of KNs (62.5% vs 18.2%, p < 0.005).

CONCLUSIONS

The low thoracoscopic detection rate of KNs may be due to the low color contrast of these small fibers. They have, however, most frequently concomitant subpleural veins that are easier to detect. These veins may serve as orientation landmarks of KNs and thus contribute to a more complete denervation improving the outcome of thoracoscopic sympathectomies.

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.

Is sympathectomy at T4 level better than at T3 level for treating palmar hyperhidrosis?

PURPOSE

We compared the results from a video-assisted thoracoscopic sympathectomy (VTS) at the T4 denervation level with those from a VTS at the T3 level for the treatment of palmar hyperhydrosis (PH).

METHODS

Seventy patients with PH were prospectively followed for VTS at the T3 or T4 denervation levels for 6 months. The end points of this study were: absence of PH, compensatory hyperhydrosis (CH), and quality-of-life assessment.

RESULTS

Sixty-seven patients reported a complete resolution of PH after surgery. One failure occurred in the T3 group and 2 in the T4 group. When anhydrosis was obtained, we noticed totally dry hands in 26 patients in the T3 group and 6 patients in the T4 group. The other 27 patients in the T4 group and 8 in the T3 group maintained a small level of sweating and were also considered to be therapeutic successes. At 6 months, 25 patients in the T4 group had some degree of CH (71.42%) and all patients in the T3 group (100%), though the T4 group had a lower degree of severity of CH at the 6-month follow-up (P < 0.05). After the operation, quality of life was improved similarly in both groups.

CONCLUSIONS

VTS at either the T3 or T4 level provides an effective treatment for PH. VTS at the T4 level is associated with a less severe form of CH. Despite the occurrence of CH, patients' quality of life is significantly improved following VTS at the T3 or T4 levels. For this reason, the T4 resection can now be used as a treatment for PH.

Evaluation of compensatory sweating after bilateral thoracoscopic sympathectomy for palmar hyperhidrosis

The study is a retrospective review of 60 patients undergoing bilateral T2-T3 thoracoscopic sympathectomy for palmar hyperhidrosis in our department between 1997 and 2003. The study was based on a telephone questionnaire and medical chart review. Forty patients (67%) replied to the questionnaire and were included in the study. Postoperative complications, therapeutic results, patient satisfaction, and the severity of compensatory sweating (CS) were assessed. In all patients both palms were dry at the end of surgery. Postoperative complications included permanent unilateral Horner syndrome, wound infection, and residual pneumothorax resolving after thoracal drainage, in one patient each. CS with different severity occurred in 35 patients (87.5%). Six patients (15%) regretted undergoing the operation due to the extent and severity of the CS seriously affecting their quality of life. Thoracoscopic sympathectomy is a simple procedure with a high success rate. However, CS is a serious complication and a significant number of patients may regret undergoing the operation; a careful selection of patients and comprehensive explanation are advisable.

Axillary Hyperhidrosis: A 5-Year Review of Treatment Efficacy and Recurrence Rates Using a New Arthroscopic Shaver Technique

BACKGROUND

Axillary hyperhidrosis is a chronic condition characterized by excess axillary perspiration. This results in considerable patient morbidity, with no consistently efficacious medical or surgical treatment method described in the literature.

METHODS

All cases of axillary hyperhidrosis over a 5-year period were reviewed retrospectively. Data were gathered by a chart review and telephone interview. Inclusion criteria included primary hyperhidrosis, failed conservative therapy, no prior surgical therapy, surgical management using a new arthroscopic shaver technique (R.L.B.-S.), and 6 months of postoperative follow-up. The technique used was consistent between surgeons. Sweating severity was assessed using a subjective numerical rating scale ranging from 1 to 10. Patient demographics, symptom history, results, and complications were analyzed.

RESULTS

Average follow-up for 50 patients meeting the inclusion criteria was 28 months. The subjective severity scale demonstrated severity of 9.8 of 10 preoperatively and 2.3 of 10 postoperatively. Three patients (6 percent) reported mild recurrence of symptoms (4.6 of 10), which was not severe enough to seek further treatment. The average follow-up of those patients was 18.5 months. An overall subjective satisfaction of 96 percent was found, with a treatment success rate of 94 percent. Complications were minimal and self-limiting. The average time away from employment was 3.9 days and the average surgical operating room time was 46 minutes.

CONCLUSIONS

The authors' new arthroscopic shaver technique is efficacious, with no significant morbidity, a 96 percent satisfaction rate, a subjectively measured 75 percent reduction of sweat, and a recurrence rate of only 6 percent. For cases of primary hyperhidrosis affecting the axilla not amenable to conservative treatment, the authors recommend an arthroscopic shaver technique as the first-line treatment of choice.

Health-related quality of life after thoracoscopic sympathectomy for palmar hyperhidrosis

BACKGROUND

Palmar hyperhidrosis is a benign functional disorder regarded as a psychological and social handicap. Improvement of the quality of life is a major goal of treatment. However, little attention has been given to quality of life after thoracoscopic sympathectomy, which is the first line of treatment for palmar hyperhidrosis. This study investigated the impact of thoracoscopic sympathectomy on subjective health-related quality of life (HRQoL) and psychological properties.

METHODS

Forty patients who underwent thoracoscopic sympathectomy were followed up for 6 months. The HRQoL measures were the Medical Outcomes Study Short Form 36 (SF-36), the Spielberger State Trait Anxiety Inventory (STAI), and the Zung Self-Rating Depression Scale (SDS). Patients were administered these questionnaires before procedure and then again at 1, 3, and 6 months after sympathectomy.

RESULTS

A comparison between the current sample and Japanese normative data for the SF-36 showed mild impairment of HRQoL before sympathectomy. However, it also showed significant improvement of the social functioning domain after sympathectomy. While there was worsening of the bodily pain and role physical domains 1 month after sympathectomy, both domains recovered in 3 months. The results of STAI showed significant improvement of both trait and state anxiety after sympathectomy. However, the results of SDS showed patients remained neurotic.

CONCLUSIONS

This study is the first to show the pattern of impairment in health status and therapeutic impact in palmar hyperhidrosis patients. Hyperhidrosis is associated with impaired HRQoL. It was also demonstrated that thoracoscopic sympathectomy is safe, minimally invasive, and improves HRQoL, even if compensatory hyperhidrosis occurs.

Selective division of T3 rami communicantes (T3 ramicotomy) in the treatment of palmar hyperhidrosis

BACKGROUND

Compensatory sweating (CS) is the main cause of a patient's dissatisfaction after sympathetic surgery for palmar hyperhidrosis. Preservation of the sympathetic nerve trunk and limitations on the range of dissection are necessary to reduce CS.

METHODS

We compared 64 patients (31 male, 33 female) (group 1) who underwent a T2 sympathicotomy between July 1998 and February 1999 and 83 patients (58 male, 25 female) (group 2) who underwent a T3 ramicotomy between August 2000 and December 2002.

RESULTS

In group 1, 60 patients (93.8%) exhibited a decreased sweating on both hands, but 4 patients (6.2%) exhibited a persistent sweating on both hands. For group 2, 58 patients (69.9%) experienced a decreased sweating on both hands, 15 patients (18.1%) experienced a persistent sweating on both hands, and 10 patients (12.0%) experienced a persistent sweating on one hand. The grade of CS in group 2 was significantly lower than in group 1 (p < 0.001) and, notably, the rate of embarrassing and disabling CS in group 2 (15.5% [9 out of 58]) was significantly lower than in group 1 (43.3% [26 out of 60], p value < 0.001). The rate of satisfaction was 78.1% (50 out of 64) for group 1 and 68.6% (57 out of 83) for group 2 with no significant statistical difference indicated (p = 0.202).

CONCLUSIONS

The incidence of sweating postoperatively was relatively high in the T3 ramicotomy group, although the T3 surgery did result in a lower incidence of CS when compared with a T2 sympathicotomy.

Treatment of hyperhidrosis with botulinum toxin

Focal idiopathic and episodic eccrine sweating of the axillae, palms, soles, and face troubles afflicted individuals with a social curse that can only be imagined by those whose hands or underarms dampen only occasionally.

Hyperhidrosis and botulinum toxin A: patient selection and techniques

Focal idiopathic excessive eccrine sweating presents most commonly as an affliction of three anatomically distinct area: the axillae, the palms and soles, and the upper face. The true incidence is not known, but about half of the patients referred to us with this condition have at least one first-degree relative similarly affected. Only a fraction of patients afflicted are thought to seek medical care because of the social stigma, lack of understanding on the part of medical providers as to the cause and nature of the problem, and, until now, lack of effective nonsurgical therapy. A large social sample is required to accurately measure both the incidence and the exact nature of the genetic influence.
