Abstract
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.

Abstract
OBJECTIVE To study the sympathetically mediated effects of transthoracic endoscopic sympathicotomy (TES) in the treatment of severe primary palmar hyperhidrosis. MATERIALS AND METHODS The effects of TES, on sympathetic ganglia at the thoracic level of 2-3, finger blood flow, temperature, and on heat and cold provocation were investigated. Middle cerebral artery (MCA) blood flow velocities were studied by transcranial Doppler. RESULTS The finger blood flow increased by about 700% after TES and finger temperature by 7.0 +/- 0.5 degrees C. Several autonomic reflexes were dramatically affected. A finger pulp-shrinking test showed a major decrease after surgery. MCA mean blood flow velocities were not affected by TES. CONCLUSIONS Besides the high success rate of good clinical effect of TES on palmar hyperhidrosis, major effects on local blood flow and temperature are elicited by TES. Complex autonomic reflexes are also affected. The patient should be completely informed before surgery of the side effects elicited by TES.

Abstract
Unilateral thoracic sympathectomy in patients with palmar hyperhidrosis causes a skin temperature drop in the contralateral hand. A cross-inhibitory effect by the post-ganglionic neurons innervating hands is postulated as a mechanism of contralateral vasoconstriction. The purpose of our study was to evaluate whether this cross-inhibitory effect also occurs in the feet. Twenty patients scheduled for thoracoscopic sympathicotomy due to palmar hyperhidosis were studied. Right T3 sympathicotomy was performed first, followed by left T3 sympathicotomy. The thenar skin temperatures of both hands and feet were continuously monitored using a thermometer and recorded before induction of anesthesia, during the operation, 4 hr after and 1 week later. Following right T3 sympathicotomy, the skin temperature of the ipsilateral hand gradually increased, however the skin temperature of the contralateral hand gradually decreased. Immediately after bilateral sympathicotomy, the skin temperature differences between hands and feet increased, but these differences decreased 1 week later. Our results show that cross-inhibitory control may exist in feet as well as in the contralateral hand. Thus, the release of cross-inhibitory control following T3 sympathicotomy results in vasoconstriction and decrease of skin temperature on the contralateral hand and feet. One week later, however, the temperature balance on hands and feet recovers.

Abstract
OBJECTIVE Postoperative compensatory sweating (PCS) is an important problem impacting on quality of life for patients after endoscopic thoracic sympathectomy (ETS). The present study investigated whether intraoperative palmar temperature and blood flow are useful for assessing PCS after ETS. METHODS Retrospectively, results were evaluated for ETS in 27 consecutive patients with primary palmar hyperhidrosis between 1996 and 2002. For all patients, bilateral nerve conduction to the palms was interrupted. The relationship between the range of PCS and intraoperative changes in palmar temperature and blood flow was investigated. RESULTS PCS developed in all cases. After completion of ETS, mean blood flow and temperature increased respectively. Significant correlations were found between the range of PCS and increases in palmar temperature (p<0.05) and blood flow (p<0.05). CONCLUSION Intraoperative monitoring of increases in palmar temperature and blood flow may be useful in patients with primary hyperhidrosis, to predict the range of PCS after ETS.

Abstract
Thoracic surgical sympathectomy is often performed to treat primary palmar and axillary hyperhidrosis. An increase in palmar skin temperature is frequently used to identify the success of the procedure. Because changes in palmar skin temperature occur secondary to changes in skin blood flow, the objective of this study was to test the hypothesis that monitoring palmar skin blood flow would provide greater temporal resolution relative to monitoring palmar skin temperature. In 11 patients with palmar and/or axillary hyperhidrosis, we measured palmar skin temperature and blood flow (via laser Doppler flowmetry) throughout the sympathectomy procedure. Five minutes after the initial cautery, skin blood flow increased from 48 +/- 7 perfusion units to 121 +/- 17 perfusion units (P <0.001), whereas no significant change in temperature was observed (31.0 degrees C +/- 0.5 degrees C to 31.3 degrees C +/- 0.5 degrees C; P >0.05). The time required to reach peak skin blood flow (22 +/- 3 min) was significantly less than the time required to reach peak skin temperature (34 +/- 0.3 min; P <0.001). Finally at 5, 10, and 15 min after the initial cautery, skin blood flow increased to a larger percentage of the total increase in skin blood flow relative skin temperature (all P <0.006). These data suggest that monitoring skin blood flow provides greater temporal resolution when compared with monitoring skin temperature during thoracic sympathectomy. However, the initial cautery of the parietal pleura over the ganglion may result in increases in skin blood flow before physical disruption of the ganglion. This occurrence may limit the utility of skin blood-flow measurements in identifying the success of the procedure.

Abstract
The assessment of sympathetic denervation to the upper extremities during surgery for hyperhidrosis is essential in predicting postoperative outcome, particularly for endoscopic thoracic chain sympathotomy, a recently described, minimally destructive technique that minimizes postoperative compensatory hyperhidrosis. To test the hypothesis that skin blood flow (SkBF; laser Doppler flowmetry) provides a faster and more reliable indication of denervation than temperature (temp), we prospectively compared palmar SkBF and fingertip temp in 10 patients undergoing endoscopic thoracic chain sympathotomy for essential hyperhidrosis. From baseline to peak values, palmar SkBF (mean +/- SEM) increased 273.3 +/- 24.7 arbitrary units and 252.4 +/- 30.1 arbitrary units, whereas temp increased 0.9 degrees C +/- 0.3 degrees C and 1.5 degrees C +/- 0.6 degrees C on the right and left, respectively. Upon effective sympathotomy of the right thoracic chain, the time to peak SkBF was 43 +/- 13 s, whereas the time to peak temp was 277 +/- 53 s (P <0.001). On the left, the time to peak SkBF was 81 +/- 14 s, and time to peak temp was 305 +/- 34 s (P <0.001). All patients considered the sympathotomy successful. We conclude that laser Doppler SkBF is superior to temp in temporal resolution for assessment of denervation during sympathotomy and that it provides a superior qualitative and quantitative adjunct to monitoring denervation.

Abstract
OBJECTIVE Video-assisted endoscopic thoracic sympathectomy is an effective surgical procedure for treating patients with palmar hyperhidrosis. An increase by more than 1 degrees C in palmar temperature has been observed to be predictive of good outcome. In this study, we investigated the use of palmar laser Doppler flowmetry as an intraoperative assessment of the efficacy of the operation. METHODS One hundred sixty-six patients underwent a total of 330 endoscopic thoracic sympathectomy procedures from March 1996 to June 2001. We studied 17 patients (15 men, 2 women) who underwent a total of 33 procedures. The patients' mean age was 27.07 +/- 7.92 years, and the mean hospital stay was 2.23 +/- 0.66 days. RESULTS Mean baseline laser Doppler blood flow was 2.63 +/- 2.56 ml/min/100 g. After the procedure, mean blood flow increased significantly to 7.24 +/- 5.88 ml/min/100 g (r = 0.768, P < 0.000, 95% confidence limit, -6.1060, -3.0946), a 232.18 +/- 219.12% increase. Mean palmar temperature increased to 1.44 +/- 1.44 degrees C. All patients experienced relief after the operation. Compensatory hyperhidrosis occurred in 10 (58.8%) of 17 patients. CONCLUSION Monitoring of palmar laser Doppler blood flow changes is a useful adjunct during endoscopic thoracic sympathectomy surgery, and, when coupled with the established methods of endoscopic visualization and palmar temperature, it can predict the success of the procedure accurately.

Abstract
OBJECT Transthoracic endoscopic T2-3 sympathectomy is currently the treatment of choice for palmar hyperhidrosis. Compensatory sweating of the face, trunk, thigh, and sole of the foot was found in more than 50% of patients who underwent this procedure. The authors conducted this study to investigate the associated intraoperative changes in plantar skin temperature and postoperative plantar sweating. METHODS One hundred patients with palmar hyperhidrosis underwent bilateral transthoracic endoscopic T2-3 sympathectomy. There were 60 female and 40 male patients who ranged in age from 13 to 40 years (mean age 21.6 years). Characteristics studied included changes in palmar and plantar skin temperature measured intraoperatively, as well as pre- and postoperative changes in plantar sweating and sympathetic skin responses (SSRs). In 59 patients (59%) elevation of plantar temperature was demonstrated at the end of the surgical procedure. In this group, plantar sweating was found to be exacerbated in three patients (5%); plantar sweating was improved in 52 patients (88.1%); and no change was demonstrated in four patients (6.8%). In the other group of patients in whom no temperature change occurred, increased plantar sweating was demonstrated in three patients (7.3%); plantar sweating was improved in 20 patients (48.8%); and no change was shown in 18 patients (43.9%). The difference between temperature and sweating change was significant (p = 0.001). Compared with the presympathectomy rate, the rate of absent SSR also significantly increased after sympathectomy: from 20 to 76% after electrical stimulation and 36 to 64% after deep inspiration stimulation, respectively (p < 0.05). CONCLUSIONS In contrast to compensatory sweating in other parts of the body after T2-3 sympathetomy, improvement: in plantar sweating was shown in 72% and worsened symptoms in 6% of patients. The intraoperative plantar skin temperature change and perioperative SSR demonstrated a correlation between these changes.

Abstract
Transthoracic endoscopic T2 sympathectomy has been widely applied to the treatment of a variety of sympathetically mediated disorders. Palmar hyperhidrosis is probably the most common indication for thoracic sympathectomy, especially in certain subtropical areas. Which sympathetic ganglion is to be ablated and how extensive such ablation is enough to eliminate palm sweating are two important issues. Intraoperative monitoring of palmar skin temperature (PST) is the most frequently used method for assessing the accuracy as well as adequacy of ablation of the target sympathetic ganglia. With continuous monitoring of bilateral PST during the operative course of T2 sympathectomy, it was possible to depict the alterations of bilateral PST in response to specific surgical procedures in a real-time manner. For each case, a PST graph was obtained, which represented the graphical expression of intraoperatively recorded bilateral PST data plotted against time. The PST graphs of 93 consecutive cases were analysed. Three types of PST graphs existed, reflecting different responses of bilateral PST to different surgical procedures during the operation. In Type I PST graph pattern, found in 58 cases, skin incision and intercostal muscle dissection caused dramatic bilateral PST drop; and unilateral T2 sympathectomy induced synchronous bilateral PST elevation. Twenty-four cases demonstrated Type II PST graph pattern, in which unilateral T2 sympathectomy caused only ipsilateral PST elevation, although the PST-depressing effect of skin incision and muscle dissection was as significant as in Type I graph pattern. In the 11 cases who showed Type III PST graph pattern, neither skin incision nor T2 sympathectomy induced any apparent changes of PST on either side, giving rise to two rather flat PST curves on the PST graphs. These findings implicate that reciprocal interactions between bilateral sympathetic activities exist in the majority of cases, and that crossover sympathetic modulation may play a role in the neural control of the sudomotor and vasomotor activities of the palms. This study also provides information regarding how PST would possibly change following specific surgical procedures during transthoracic endoscopic T2 sympathectomy, which may be of importance to those who use intraoperative PST monitoring as a guide in determining whether or not the correct sympathetic ganglia are ablated for adequate sympathetic denervation of the palms.

Abstract
OBJECTIVE A retrospective study presenting our experience with upper thoracic endoscopic sympathectomy in patients with primary palmar hyperhidrosis. METHODS One hundred patients (46 women and 54 men) underwent bilateral uniportal endoscopic thoracic sympathectomy since January 1, 1995. Age distribution ranged from 12 to 54 years (mean, 23.4 yr). RESULTS Sympathectomy on both sides was accomplished within 30 minutes in a single stage. Ninety-six patients (96%) had an uneventful postoperative course and were discharged the following day. Four patients with residual hemothorax required intercostal drainage and were discharged on the third postoperative day. Ninety-six patients were completely satisfied with immediate and permanent relief of palmar perspiration. Compensatory hyperhidrosis was the major complication, which was usually mild and tolerable after reassurance. In only eight patients (8%) was the compensatory hyperhidrosis considered bothersome, requiring treatment with aluminum chloride in ethanol solution at 25%. There was no mortality. Recurrence of palmar hyperhidrosis has been noticed in five patients (5%) during the follow-up period (range, 2-56 mo; mean, 12 mo). At the time of reoperation, a remaining branch of the sympathetic chain could be observed and coagulated. CONCLUSION We consider thoracoscopic sympathectomy to be a simple, safe, and effective method for treating palmar hyperhidrosis. It is an effective method for treating patients with palmar hyperhidrosis, with a shorter operation time, fewer hospital days, and a better cosmetic result, as compared with the open approaches.

Abstract
OBJECT Transthoracic endoscopic T-2 sympathectomy is currently the treatment of choice for palmar hyperhidrosis (PH). Intraoperative monitoring of palmar skin temperature (PST) is often used to assess the adequacy of sympathetic ablation. The aim of this study was to investigate the time course of PST changes during the operation and to determine factors involved in the sympathetic modulation of the palmar skin blood flow. METHODS Eighty-one patients with PH underwent bilateral transthoracic endoscopic sympathectomy of T-2 in which continuous intraoperative PST monitoring was used. Palmar skin temperature data, recorded every 30 seconds throughout the operation, were plotted against time, and a graph of two PST curves was obtained in each case. A multiphasic curve pattern of great similarity was observed in nearly 70% of cases. Specific PST readings at different operative stages were collected and averaged for all cases. The trend of PST changes in response to different procedures during the operation was analyzed. It was found that unilateral procedures caused simultaneous bilateral PST alterations. In almost all cases, bilateral PST was dramatically lowered when unilateral skin incision and intercostal muscle dissection were performed. The temperature remained low until the T-2 sympathectomy was finished on one side. In addition, unilateral T-2 sympathectomy induced synchronous elevation of bilateral PST. However, the ipsilateral response was significantly stronger than that on the contralateral side. CONCLUSIONS Although intraoperative monitoring of PST is a reliable guide for surgeons performing endoscopic transthoracic sympathectomy, it is important to realize that PST fluctuates at different stages during the operation and that surgical procedures themselves can significantly influence PST readings. The PST data recorded at specific time points, therefore, can be misleading in terms of accuracy and the completeness of ablation of the target sympathetic ganglia, especially when the sympathetic trunk or ganglia are anatomically aberrant.

Abstract
The purpose of this article was to systematically review the literature in order to assess (1) the current indications for surgical sympathectomy and (2) the incidence of late complications collectively and per indication. All types of upper or lower limb surgical sympathectomies are included. An extensive search strategy looked for controlled trials and observational studies or case series with an english abstract. Out of 1,024 abstracts from MEDLINE and 221 from EMBASE, 135 articles reporting on 22,458 patients and 42,061 procedures (up to april 1998) fulfilled the inclusion criteria. Weighted means were used to control for heterogeneity of data. No controlled trials were found. The main indication was primary hyperhidrosis in 84.3% of the patients. Compensatory hyperhidrosis occurred in 52.3%, gustatory sweating in 32.3%, phantom sweating in 38.6%, and horner's syndrome in 2.4% of patients, respectively, with cervicodorsal sympathectomy, more often after open approach. Neuropathic complications (after cervicodorsal and lumbar sympathectomy) occurred in 11.9% of all patients. Compensatory hyperhidrosis occurred 3 times more often if the indication was palmar hyperhidrosis instead of neuropathic pain (52.3% versus 18.2%), whereas neuropathic complications occurred 3 times more often if the treatment was for neuropathic pain instead of palmar hyperhidrosis (25.2% versus 9.8%).
