ETS is not without its critics

"ETS is not without its critics. Like any major surgical procedure, there is an operative risk, with a prominent fatality in Dublin a few years ago. Homer's syndrome can result. The most common problem is the development of 'compensatory hyperhidrosis', usually on the back. In 2003, ETS was banned in its birthplace, Sweden, due to overwhelming complaints by disabled patients."

Sympathectomy causes wall thinning, elongation, convolution, and aneurysm formation

"Sympathectomy causes basilar artery enlargment, which is beneficial for maintaining cerebral blood flow; however, it also causes wall thinning, elongation, convolution, and aneurysm formation, which may be hazardous in stenoocclusive carotid artery disease. Sympathectomy can prevent new vessel formation and hyperthyrophic changes at the posterior circulation. Neovascularisation is not detected adequately in sympathectomised animals."

Peripheral neuropathy gives reduced sensation and sweat ability of the arms and legs but can lead to compensatory sweating of the trunk and head.

Google Translate:

Peripheral neuropathy gives reduced sensation and sweat ability of the arms and legs but can lead to compensatory sweating of the trunk and head.

Horner's syndrome due sympatikusskada means, for example Anhidrosis on one half of the face which can then be followed by compensatory hyperhidrosis on the other side. Harlequin syndrome is another name in the same condition in which instead focuses on the color difference where the sympatikusskadade page turns white and the other side is red with exertion. The look can then recall a home to Harelquin.

Freys'syndrom arise after salivary gland surgery faulty growing parasympathetic salivary fibers innervate the sweat glands in the cheek. This means that when the patient eats or even just thinking about food so producing a profuse perspiration from his cheek

Sympathectomy was common in the 90s in Sweden. At indications palmar and axillary hyperhidrosis, redness, or social phobia, burned the thoracic sympathetic ganglia endoscopically. Compensatory hyperhidrosis developed below the nipples of a large number of patients 1-6 months after sympatektomin.

This is the first study to examine post-SE (post-sympathectomy) dysfunction objectively

This is the first study to examine post-SE dysfunction objectively using TG after ALIF and XLIF, and the first to evaluate clinically, the severity of the post-SE syndrome. Before surgery we cannot foresee potentially poor SE results. For this reason, injury to the sympathetic chain during surgery must be avoided. The advantage of TG for identifying SE is its non-invasiveness and reliability.

The aim of this study was to identify retrospectively, lumbar sympathectomy (SE) using thermography (TG) and to evaluate clinically, the severity of post-sympathectomy (post-SE) dysfunction after anterior and lateral lumbar interbody fusion procedures (ALIF, XLIF).

Sympathectomy (ETS) a psychosurgery?

Financial Review - News Store: "It's not unusual to hear people who have undergone sympathectomies describe themselves as feeling emotionally "colder" than before. Among psychologists and neurologists alike there is concern, but no evidence, that the procedure limits alertness and arousal as well as fear, and might affect memory, empathy and mental performance. Professor Ronald Rapee, the director of the Centre of Emotional Health at Sydney's Macquarie University, says he's counselled several people who complain of feeling "robot-like" in the long-term wake of the operation. "They're happy they no longer blush, but they miss the highs and lows they used to feel.""

Dr. Telaranta treating fear, stuttering, stage fright, blushing with sympathectomy. Is ETS a psychosurgery?

Dr. Telaranta | Blog by Dr. Telaranta: "As a treatment, sympathetic blocking could be effective. Fortunately one can test whether it’ll have an effect, to a pretty high level of certainty, by first administering a temporary block t. Sympathetic block is usually effective in reducing all types of fear, why not also in reducing the fear of stuttering.

Sympathetic block typically has the highest likelihood of effective results on both schizophrenia and tremor when fear or anxiety plays a significant part in the onset of symptoms. It is also very effective in treating social phobia, stage fright and blushing. A stage fright-like fear of public presentations is likely common amongst those who stutter."

"We quickly discovered that lay people often lack the (medical) knowledge to make well-considered judgements"

Jane McCredie: Wishing on risks

Moreover, GPs and plastic surgeons can both be approached directly by patients in The Netherlands. The physicians studied raised many arguments that were expected: they used patient autonomy, risks and benefits, normality and justice to limit wish-fulfilling medicine. In addition, arguments new to this debate were uncovered, which were frequently used to justify compliance with a patient's request. Such arguments seem familiar from conventional medicine, including empathy, the patient–doctor relationship and reassurance. Moreover, certain arguments that play a significant role in the literature on wish-fulfilling medicine and enhancement were not mentioned, such as concepts of disease and the enhancement–treatment dichotomy and ‘suspect norms’.

The sympathetic system is responsible for the physiological responses to emotional states

The common epithet of “fight or flight” is being enlarged to be “fight, flight, or fright” or even “fight, flight, fright, or freeze.” Cannon’s original contribution was a catchy phrase to express some of what the nervous system does in response to a threat, but it is incomplete. The sympathetic system is responsible for the physiological responses to emotional states. The name “sympathetic” can be said to mean that (sym- = “together”; -pathos = “pain,” “suffering,” or “emotion”).

Following a peripheral nerve injury, a sterile inflammation develops in sympathetic and dorsal root ganglia

Following a peripheral nerve injury, a sterile inflammation develops in sympathetic and dorsal root ganglia (DRGs) with axons that project in the damaged nerve trunk. Macrophages and T-lymphocytes invade these ganglia where they are believed to release cytokines that lead to hyperexcitability and ectopic discharge, possibly contributing to neuropathic pain. Here, we examined the role of the sympathetic innervation in the inflammation of L5 DRGs of Wistar rats following transection of the sciatic nerve, comparing the effects of specific surgical interventions 10-14days prior to the nerve lesion with those of chronic administration of adrenoceptor antagonists. Immunohistochemistry was used to define the invading immune cell populations 7days after sciatic transection. Removal of sympathetic activity in the hind limb by transecting the preganglionic input to the relevant lumbar sympathetic ganglia (ipsi- or bilateral decentralization) or by ipsilateral removal of these ganglia with degeneration of postganglionic axons (denervation), caused less DRG inflammation than occurred after a sham sympathectomy. By contrast, denervation of the lymph node draining the lesion site potentiated T-cell influx. Systemic treatment with antagonists of α1-adrenoceptors (prazosin) or β-adrenoceptors (propranolol) led to opposite but unexpected effects on infiltration of DRGs after sciatic transection. Prazosin potentiated the influx of macrophages and CD4+ T-lymphocytes whereas propranolol tended to reduce immune cell invasion. These data are hard to reconcile with many in vitro studies in which catecholamines acting mainly via β2-adrenoceptors have inhibited the activation and proliferation of immune cells following an inflammatory challenge.

Immune cell involvement in dorsal root ganglia and spinal cord after chronic constriction or transection of the rat sciatic nerve.

Hu P, Bembrick AL, Keay KA, McLachlan EM.

Chronic constriction injury (CCI) of the sciatic nerve in rodents produces mechanical and thermal hyperalgesia and is a common model of neuropathic pain. Here we compare the inflammatory responses in L4/5 dorsal root ganglia (DRGs) and spinal segments after CCI with those after transection and ligation at the same site. Expression of ATF3 after one week implied that 75% of sensory and 100% of motor neurones had been axotomized after CCI. Macrophage invasion of DRGs and microglial and astrocytic activation in the spinal cord were qualitatively similar but quantitatively distinct between the lesions. The macrophage and glial reactions around neurone somata in DRGs and ventral horn were slightly greater after transection than CCI while, in the dorsal horn, microglial activation (using markers OX-42(for CD11b) and ED1(for CD68)) was greater after CCI. In DRGs, macrophages positive for OX-42(CD11b), CD4, MHC II and ED1(CD68) more frequently formed perineuronal rings beneath the glial sheath of ATF3+ medium to large neurone somata after CCI. There were more invading MHC II+ macrophages lacking OX-42(CD11b)/CD4/ED1(CD68) after transection. MHC I was expressed in DRGs and in spinal sciatic territories to a similar extent after both lesions. CD8+ T-lymphocytes aggregated to a greater extent both in DRGs and the dorsal horn after CCI, but in the ventral horn after transection. This occurred mainly by migration, additional T-cells being recruited only after CCI. Some of these were probably CD4+. It appears that inflammation of the peripheral nerve trunk after CCI triggers an adaptive immune response not seen after axotomy.

BioEdge: Evidence-based medicine comes under attack: "evidence-based medicine has its critics, as a bilious outbreak of comment and letters in the BMJ demonstrated recently. Early last month a Glasgow GP, Des Spence, said that the system of EBM had been corrupted. “If we don’t tackle the flaws of EBM there will be a disaster, but I fear it will take a disaster before anyone will listen,” he wrote.

How could anyone fault the notion of treatment based on scientifically validated evidence? No one. But the critics of EBM argue heatedly that the standards for the evidence are often low and tainted by commercial or personal interests."

prolongation of the isometric (tension) period (TP) of the left ventricle occurred in the majority (72 per cent) of all cases after sympathectomy

The prolongation of the isometric (tension) period (TP) of the left ventricle which occurred in the majority (72 per cent) of all cases after unilateral or bilateral transthoracic sympathectomy (without or with unilateral or bilateral transthoracic splanchnicotomy) indicates a diminution of inotropic cardiac action. It can be assumed to correspond to the cholinergic (vagal) preponderance which results from a partial or complete sympathetic denervation of the heart. Reduction of the pulse pressure oc-

curred in 56 per cent of the cases, probably due to the same mechanism.

change in sympathetic nervous system activity after thoracic sympathectomy

The photoplethysmographic (PPG) signal, which measures cardiac-induced changes in tissue blood volume by light transmission measurements, shows spontaneous fluctuations. In this study, PPG was simultaneously measured in the right and left index fingers of 16 patients undergoing thoracic sympathectomy, and, from each PPG pulse, the amplitude of the pulse (AM) and its maximum (BL) were determined. The parameter AM/BL is proportional to the cardiac-induced blood volume increase, which depends on the arterial wall compliance. AM/BL increased after the thoracic sympathectomy treatment (for male patients, from 2.60±1.49% to 4.81±1.21%), as sympathetic denervation decreases arterial tonus in skin. The very low-frequency (VLF) fluctuations of BL or AM showed high correlation (0.90±0.11 and 0.92±0.07, respectively) between the right and left hands before the thoracic sympathectomy, and a significant decrease in the right-left correlation coefficient (to 0.54±0.22 and 0.76±0.20, respectively) after the operation. The standard deviation of the BL or AM VLF fluctuations also reduced after the treatment, indicating sympathetic mediation of the VLF PPG fluctuations. The study also shows that the analysis of the PPG signal and the VLF fluctuations of the PPG parameters enable the assessment of the change in sympathetic nervous system activity after thoracic sympathectomy.

Results

                Graph 1 shows the survival rate in both sympathectomised and non sympathectomised rats after the administration of YA cells. The graph shows an overall shorter survival rate of sympathectomised rats. In both groups there is a steep decrease in survival after 15 days, causing the median survival rate (18 days) of both groups to overlap. On the other hand the net survival rate is increased in non sympathectomised rates by 6 days

significant change after sympathectomy: reduced sympathetic and increased vagal tone

The HRV analysis showed a significant change of indices reflecting sympatho-vagal balance indicating significantly reduced sympathetic (LF) and increased vagal (HF, rMSSD) tone. These changes still persisted after 2 years. Global HRV increased over time with significant elevation of SDANN after 2 years. QT dispersion was significantly reduced 1 month after surgery and the dispersion was further diminished 2 years later.

Decreased HRV is predictive of adverse cardiovascular outcomes in a variety of disease states

Water immersion-induced skin wrinkling (WISW) is dependent on intact peripheral sympathetic function. WISW was hypothesized to reflect autonomic function in subjects with- out peripheral neuropathy. We prospectively studied 70 healthy subjects (aged 31 88 years, 63% females) without cardiovascular risk factors or neurological disease. All sub- jects underwent short-term heart rate variability (HRV) stud- ies. Time and frequency domain variables were derived in- cluding the HRV index. WISW was graded using a previously validated scale of 1–4 of which 18.6% of subjects exhibited grade 1 (minimal) WISW and 35.7% had grade 2 WISW. On multivariate analysis using the HRV index, WISW was inde- pendently related to height and the HRV index. We conclude that WISW is related to central autonomic function.

Although the mechanism is not fully understood, WISW is felt to be caused by passive diffusion of water across the stratum corneum into the sweat ducts, which in turn alters electrolyte balance, decreases membrane stabilization, increases sympathetic neural firing and stimulates vasoconstriction [1–3, 8].WISW is decreased in diabetic patients and in patients after cervical sympathectomy [4, 9].

Heart rate variability (HRV) is the beat-to-beat variation in cardiac cycle length due to autonomic influence on the sinus node. Decreased HRV is predictive of adverse cardiovascular outcomes in a variety of disease states[5]. The influence of the central nervous system activity on autonomic function suggests that HRV may be a useful prognostic indicator in patients with cerebrovascular events [6].

Is sympathectomy (ETS) safe and effective?

Well, it depends on who you ask.

We already know what the surgeons who offer the surgery have to say about it, as most of us was conned into having the surgery. We also know what these surgeons have to say about non-surgical options (ineffective, tedious, time-consuming, expensive, not permanent, resulting in disabling side-effects, very painful, useless - on one website patients are told that application of BOTOX requires general anaesthesia, just to scare them off that one... : http://archive.is/lSWd0 ). The question is answered very differently when you ask a medical professional who offers these non-surgical treatment options. Their advice and their version of FACTS always depends on the treatment and technique they have on offer. 

A very simple exercise: print out the texts from few of these websites and offer it to someone to read. Then let them guess what they think which treatment the medical professional is siding with, that is: which treatment is being offered and advertised by them. 

Here is a sample. You will most certainly detect that this medical professional is NOT offering ETS, as he selected different FACTS about the procedure and it's results.

Natural bodily functioning does not include “purely autonomic” or “purely somatic” responses, just as it does not include ‘purely sympathetic” or “purely parasympathetic” responses

Langley initially expected to find afferent cell bodies in autonomic ganglia, with projections to other ganglia. He believed that activation of these “autonomic afferents” should lead to purely autonomic responses. However Langley’s own careful work demonstrated that there were no such neurons.

The fundamentally important point is that integrative processes responsible for the organization of visceral function occur principally within the central nervous system (brain and/or spinal cord). Both somatic and visceral afferents result in complex, brain mediated, responses that include somatic and visceral function. Autonomic motor activity can be generated by both somatic and visceral inputs to the CNS, and visceral inputs to the CNS initiate responses that are both somatic and autonomic. Natural bodily functioning does not include “purely autonomic” or “purely somatic” responses, just as it does not include ‘purely sympathetic” or “purely parasympathetic” responses.

electric stimulation of the sympathetic cord in the upper thoracic level on the middle cerebral artery blood flow velocity

The effect of electric stimulation of the sympathetic cord in the upper thoracic level on the middle cerebral artery blood flow velocity (V(MCA)) in humans was examined using transcranial Doppler sonography monitoring during surgery for palmar hyperhidrosis. Sympathetic stimulation resulted in marked and rapid increases Of V(MCA). The responses were preceded by prompt increases of mean arterial blood pressure (MABP) and heart rate (HR). Division of the sympathetic cord cranially or caudally to the stimulation site partially reduced the V(MCA), MABP and HR responses. Both these operations reduced sympathetic pathways to the heart as reflected by a decrease in HR and MABP. The integrity of the sympathetic pathway from the stimulation site through the superior cervical ganglion and the carotid plexus was not a prerequisite for a V(MCA) response. Our data suggest that the V(MCA) increase mainly results from stimulation of the heart and the cardiovascular system, resulting in marked increases of blood pressure and heart rate.

Postsympathectomy pain of such severity that parenteral narcotics afforded no relief

Fifty-six consecutive patients who subsequently underwent ninety-six lumbar sympathectomies were studied prospectively with regard to the development of postoperative pain. Pain after operation was observed in thirty-four extremities by twenty-five of the patients (35 per cent). It began abruptly an average of twelve days after operation and was often accentuated nocturnally. The pain was almost always described as a deep, dull ache and persisted two to three weeks before spontaneously remitting. Postsympathectomy pain of such severity that parenteral narcotics afforded no relief developed in two of these fifty-six patients and in nine additional patients. Treatment with carbamazepine produced dramatic reduction in the intensity of pain in seven of these nine patients within twenty-four hours after the institution of therapy. Two patients were given intravenous diphenylhydantoin and both experienced immediate relief of pain. The mechanisms of the syndrome and of the action of these drugs are uncertain.

post-sympathectomy hyperalgesia

Behavioral test of tolerance for aversive mechanical stimuli in sympathectomized cats.

W J Roberts

  and 

D L Rhodes

Cats were studied behaviorally to determine their suitability as an animal model for the post-sympathectomy hyperalgesia reported to occur in humans. For this study a device and methodology were developed which allow humane testing of tolerance for intense mechanical stimulation of the hindlegs. Behavioral tolerance was measured quantitatively before and after unilateral sympathectomy. The results from this preliminary study of 6 cats are remarkably similar to those reported for humans; 1 of the 6 cats showed a decreased tolerance on the sympathectomized side which was delayed in onset and of limited duration. The new methodology appears to provide relatively stable, quantitative measures of tolerance for aversive stimulation, and the cat shows promise as an animal model for post-sympathectomy hyperalgesia.

significant number of primary hyperhidrosis patients (more than 70%) were so pleased with the results that they decided to forgo the surgery

At the beginning of our study, thoracic sympathectomy was indicated indiscriminately to all primary hyperhidrosis patients. The authors observed a number of patients who were dissatisfied with the results obtained from this technique, particularly due to the undesirable but frequent side effect of compensatory hyperhidrosis. Hyperhidrosis is a condition that deeply affects the individual's emotional component, and many of them, despite being warned previously, are not psychologically prepared to address this new situation. The authors then included a psychologist in the study and directed the patients for routine psychological evaluations to prepare and better select them for surgery. In addition, the authors began to study a pharmacological formula to medicate these patients for the same purpose. Oxybutynin is an anticholinergic drug that has been used safely at high doses (up to 15 mg/day) to treat micturition disorders, and a side effect observed in these patients has been diminished sudoresis. Studies conducted by our group have documented the clinical benefits of a low dose of oxybutynin (10 mg/day). The authors found that a significant number of primary hyperhidrosis patients (more than 70%) were so pleased with the results that they decided to forgo the surgery [50-53].

Neuralgia due to sympathectomy

Depending on the skill of the surgeon and difficulty encountered performing various intraoperative maneuvers, the incidence of complications following sympathectomy should be the same as that following any other extraperitoneal or extrapleural operation. However, a frequent complication following sympathectomy, and one which is apparently unrelated to operative technique, is that of postsympathectomy neuralgia.

This neuralgia is characterized by aching thigh pain after lumbar sympathectomy or aching shoulder and arm pain after cervical sympathectomy. The pain is intense in severity, sudden in onset and disappearance, and not related to any major neurologic manifestations.

Recently we have reviewed the files of the Vascular Surgical Service at the West Roxbury Veteran's Hospital and the literature on this condition. This report is a presentation of our findings.

Incidence  Pain following sympathectomy has been described as "an all too common complaint."⁸ Reports have varied in incidence from 2.1% to "practically every case."

Autonomic neuropathy in the skin following sympathectomy

In diabetics with the anhidrotic syndrome, autonomic nerve fibres were studied in skin biopsies using argentic techniques and light microscopy. The Minor test was used to differentiate normal from anhidrotic skin areas. In the anhidrotic areas, histology of the nerve fibres showed beading, spindle-shaped thickening and fragmentation adjacent to the sweat glands. These changes were similar to those observed in two patients who had previously undergone lumbar sympathectomy. No abnormalities of the sympathetic nerve endings could be found in biopsies taken from normal areas of the forearm of the same patients. We conclude that the diabetic anhidrotic syndrome, a form of diabetic autonomic neuropathy, is due to a lesion of the sympathetic nerve supply to the skin.

after sympathectomy the hands may become hyperkeratotic, with fissuring and scaling

Sympathectomy for palmar hyperhidrosis is effective, but has risks associated with surgery and a permanent non-sweating hand, which may become hyperkeratotic, with fissuring and scaling.

Cilio-spinal center can extend to T5

The ciliospinal reflex (pupillary-skin reflex) consists of dilation of the ipsilateral pupil in response to pain applied to the neck, face, and upper trunk. If the right side of the neck is subjected to a painful stimulus, the right pupil dilates (increases in size 1-2mm from baseline). This reflex is absent in Horner's syndrome and lesions involving the cervical sympathetic fibers. The enhanced ciliospinal reflex in asymptomatic patients with cluster headache is due to preganglionic sympathetic mechanisms.

The cilio-spinal center is not sharply confined to TI spinal level, but may extend downwards as low as T5

Endoscopic sympathectomy is not minimally invasive

The term ‘‘minimally invasive surgery’’ was initially applied to coelioscopic procedures such as laparoscopic cholecystectomy and hernia repair, thoracoscopic sympathectomy, and arthroscopy, but has since been abandoned, because doing the same operation through a smaller incision is not necessarily less invasive. The term ‘‘minimally invasive parathyroidectomy’’ does not fully convey the nature of the techniques, and, as previously debated in the wider field of minimal-access surgery, carries connotations of increased safety that are not necessarily supported by the existing data [12].

This is how "Australia’s leading source for trustworthy medical information" describes sympathectomy

"Sympathectomy is a procedure that is used to treat neuropathic pain. It interrupts the sympathetic nervous system either temporarily or permanently."

progressive hemifacial atrophy following sympathectomy for hyperhidrosis

Some authors consider the disease a variant of mor- phea because the histologic changes are identical to deep scleroderma.2 The possible etiologies include sympathetic denervation, trauma, vascular malformations, immunologic abnormality, heredi- tary disease, or infection by a slow virus.3 To our knowledge, this is the first report of a young patient with a possible association between Parry-Romberg syndrome and thoracoscopic sympathectomy.

Theoretically, thoracoscopic sympathectomy may cause 2 of the aforementioned etiologies of Parry- Romberg syndrome: sympathetic denervation and trauma. Thoracoscopic sympathectomy is a surgical technique for the treatment of palmar hyperhidrosis.

The operation ablates the upper thoracic sympa- thetic nerve ganglions responsible for nerve stimu- lation of the sweat glands of the upper limbs. The most significant complication is Horner’s syn- drome, which results from injury to the stellate sympathetic ganglion.7 In a summary of sympa- thectomies in 67 children and adolescents, compli- cations included Horner’s syndrome in 1 patient (1%) and varying degrees of compensatory sweat- ing in 30 patients (45%).8 Despite the evidence from animal studies that sympathectomy can result in facial atrophy, to our knowledge, there were no previous reports of such an association in humans.
