Permanent pain following sympathectomy

The mean inpatient pain scores were significantly higher in the biportal group (1.2±0.6) than that in the uniportal group (0.8±0.5, P=0.025). For the first three weeks after operation, four out of 20 (20%) patients in the uniportal group constantly suffered from mild or moderate residual pain while eight out of 25 (32%) cases in the biportal group (P=0.366). Among them, two cases in the uniportal group and five cases in the biportal group need to take analgesics.

The so called 'compensatory sweating' is NOT compensatory - BMJ Best Practice

"When patients with intense CH are analyzed, we observe that the amount of released sweat seems to be much greater than was that occurring at the primary hyperhidrosis location, not translating a simple compensation or sweating transference from one site to the other. Therefore, this hyperhidrosis seems to be reflex, mediated neurologically in the sweating regulatory center in the hypothalamus.

In order to avoid this neurologically mediated reflex, the sympathetic afferents to the hypothalamus should be restored, allowing negative feedback to block the efferent projection of the sweating regulatory center on the periphery.(14) Therefore, only the reinnervation of the sectioned sympathetic chain could recover this reflex."

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.

Abstract
Bone modeling and remodeling are highly regulated processes in the mammalian skeleton. The exact mechanism by which bone can be modeled at a local site with little or no effect at adjacent anatomic sites is unknown. Disruption of the control of modeling within the temporal bone may lead to various bone disease such as otosclerosis, osteogenesis imperfecta, Paget's disease of bone, fibrous dysplasia, or the erosion of bone associated with chronic otitis media. One possible mechanism for such delicate control may be related to the ubiquitous and rich sympathetic innervation of all periosteal surfaces. Previous studies have indicated that regional sympathectomy leads to qualitative alterations in localized bone modeling and remodeling. In this study, unilateral cervical sympathectomy resulted in significant increases in osteoclast surface and osteoclast number within the ipsilateral bulla of experimental animals. The mechanisms by which sympathectomy leads to increased local bone loss is unknown. Potential mechanisms include disinhibition of resorption, secondary to the elimination of periosteal sympathetics, as well as indirect vascular effects."

Abstract
Rats with chemical sympathectomy, induced either at neonatal age (long-term sympathectomy) or in adult animals (short-term sympathectomy) by guanethidine or by 6-hydroxydopamine, were used to determine the contribution of sympathetic noradrenergic fibres to afferent neuron-mediated responses and to non-neurogenic inflammation in the rat. Following long-term sympathectomy with 6-hydroxydopamine there was a 66% depletion of noradrenaline in the paw skin. This was accompanied by a 20-53% increase in the levels of sensory neuropeptides in the paw skin and sciatic nerve. A hypersensitivity towards heat stimuli was observed in the tail immersion test. "

Drawbacks of thoracoscopic sympathectomy

Side effects after thoracoscopic sympathectomy have been discussed
widely in Taiwan society in the past few months. Lots of people in Taiwan
suffer from hyperhidrosis palmaris. Thoracoscopic sympathectomy is covered
by our National Health Insurance, and yet patient billing for this
operation does not exceed US$ 60. This is why this operation is so popular
here (1). However, patients with serious compensatory sweating must change
clothes several times a day (some complain they change as often as 10
times a day), resulting in a serious impact on work and social
interaction. Patients suffering from such serious side effects in Taiwan
have formed a support group based on an Internet discussion forum to
request the government to take this problem seriously
(http://home.pchome.com.tw/family/vivi12175/). Since October 2004, The
Department of Health Executive, Yuan, Taiwan, has prohibited surgeons from
performing this operation on patients under 20 years of age. To our
knowledge, this type of Internet-based support group also exists in
England (http://www.noetsuk.com/), Sweden
(http://home.swipnet.se/sympatiska/index3.htm), Australia (http://www.ets-
sideeffects.netfirms.com/), Spain
(http://www.terra.es/personal8/hiperhidrosis/principal.htm) and Japan
(http://www.geocities.jp/etscontroversialop/index.html). Thoracoscopic
sympathectomy is a relatively safe and simple procedure, however, the side
effects are potentially devastating. All surgeons who do the operation and
individuals preparing to undergo this treatment should know this well.

significant shift in heart rate variability following sympathotomy for hyperhidrosis

Compared with preoperative variables, there was a significant increase in the number of adjacent normal R wave to R wave (R- R) intervals that differed by more than 50 ms, as percent of the total number of normal RR intervals (pNN50); root mean square difference, the square root of the mean of the sum of squared differences between adjacent normal RR intervals over the entire 24-hour recording; standard deviation of the average normal RR in- terval for all 5-minute segments of a 24-hour recording (SDANN) after thoracic sympathotomy. Low frequencies (LF, 0.04 to 0.15 Hz) decreased significantly.

Inflammation in dorsal root ganglia after peripheral nerve injury: Effects of the sympathetic innervation

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 gan- glia 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 in- terventions 10–14 days prior to the nerve lesion with those of chronic administration of adrenoceptor antago- nists. Immunohistochemistry was used to define the invading immune cell populations 7 days after sciatic transection. Removal of sympathetic activity in the hind limb by transecting the preganglionic input to the rele- vant 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 in- flux. 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 inflamma- tory challenge.

lowering of heart rate and blood pressure, decreased responsiveness of the cardiocirculatory system to emotional stimuli after sympathectomy

"lowering of heart rate and blood pressure, decreased responsiveness of the cardiocirculatory system to emotional stimuli: it is an effect that is especially noticeable in patients operated on for erythrophobia and less evident in those operated for hyperhidrosis. It is almost always a welcome phenomenon, which contributes considerably to the feeling of tranquility and serenity that generally supersedes anxiety. Excessive reduction in blood pressure or heart rate may lead to a state of weakness and fatigue that may require removal of the clips in approx. 2%. This rare state of asthenia contrasts with the increased energy and vigor that most patients experience when they feel freed from overwhelming anxiety."    

"The neurovegetative nervous system is, however, very dynamic and tends to adapt continuously during lifetime to all environmental or organic changes and conditions. Therefore, it reacts very individually when a reflex circuit has been blocked. The resulting side effects cannot be predicted in detail, and though they in most patients are relatively mild or even absent, there is a small group of patients developing heavy side effects. Therefore, surgery should only be considered in carefully selected cases in whom non-invasive treatment has failed and in whom the detrimental consequences of erythrophobia regarding the psychosocial situation and the quality of life is such to justify more adverse side effects. It should also always be kept in mind that therapy can be ineffective and that, in the long term, 10-15% of patients do not consider themselves satisfied with the result of surgery. In any case, the author prefers the use of a potentially reversible surgical technique (ESB), instead of destructive techniques (cutting, coagulation, removal of ganglia)."

medical procedures are misrepresented in the media

"If your patients rely on the mainstream media for medical advice, they may well think that cancer has been cured many times over, and have other inflated views about the benefits of new treatments and tests.

AND they probably would be shocked to learn about the potential downsides of many medical interventions, let alone costs.

That’s the conclusion of a comprehensive analysis of almost 2000 medical news items published in the US by print, online and television outlets between 2006 and 2013.

It was undertaken by the media watchdog Health News Review, and recently published in JAMA Internal Medicine (5 May, 2014). Most stories were judged unsatisfactory in how they covered the costs, benefits, harms and quality of the evidence supporting the new treatment or test, and how it was compared to alternatives.

“Drugs, medical devices, and other interventions were usually portrayed positively; potential harms were minimised and costs were ignored,” wrote the founder of Health News Review, Gary Schwitzer."

Chest wall paresthesia affects a significant but previously overlooked proportion of patients following sympathectomy

Paresthetic discomfort distinguishable from wound pain was described by 17 patients (50.0%). The most common descriptions were of ‘bloating’ (41.2%), ‘pins and needles’(35.3%), or ‘numbness’ (23.5%) in the chest wall. The paresthesia resolved in less than two months in 12 patients (70.6%), but was still felt for over 12 months in three patients (17.6%). Post-operative paresthesia and pain did not impact on patient satisfaction with the surgery, whereas compensatoryhyperhidrosis in 24 patients (70.6%) did (P=0.001). The rates and characteristics of the paresthesia following needlescopic VATS are similar to those observed after conventional VATS. Conclusions: Chest wall paresthesia affects a significant but previously overlooked proportion of patients following needlescopic VATS.

the severity of post-sympathectomy (post-SE) dysfunction is unpredictable

 "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).
METHODS:
Twenty eight patients with suspected SE were referred for TG to both legs. They completed our questionnaire on severity of difficulties after SE. We evaluated the ability of physical examinations to reveal the SE in contrast to TG and compared the symptoms (warmer leg and inhibited leg sweating) of SE with questionnaire responses as subjective measure and TG as objective measure.
RESULTS:
SE was diagnosed in 0.5% after ALIF at L5/S1, in 15% after ALIF at Th12-L5 and in 4% after XLIF at T12-L5. SE severely reduced the quality of life in two cases. The ability to distinguish differences in leg temperature by palpation after SE was found in 32%. All physical examinations together were insufficient for reliably disclosing SE. Subjective symptoms of SE were often false positive and proven SE by TG was often a clinically false negative.
CONCLUSION:
This is the first study to examine post-SE dysfunction objectivelya 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.

most of the existing literature is geared towards assessing only the effectiveness of the surgical sympathectomy

"Given the fact that most of the existing literature is geared towards a) assessing only the effectiveness of the surgical sympathectomy procedures, and b) publishing only studies with positive results, adverse effects and complications are not systematically reported but rather as a secondary outcome. It seems, therefore, highly likely that the complications as reported here, are truly underestimated.



The study indicates that surgical sympathectomy, irrespective of operative approach and indication, may be associated with many and potentially serious complications.

"Ferrar believes much of the controversy lies in surgeons, mainly in America, who perform the surgery on anyone who asks for it, rather than the severe end of the spectrum.
"In America there are so many that have been operated on when it hasn't been necessary, or the surgeon has given the patient false expectations, that there are support groups for people who've had complications or adverse effects. The people that come to me are almost self-selecting; they've tried everything else."

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."

sympathectomy, by chemical or surgical means, is based on such anecdotal observation and small case studies which have failed to stand up to scientific scrutiny

Clinical trials do exist and their inability to demonstrate effectiveness suggests an obvious conclusion: the argument for sympathectomy, by chemical or surgical means, is based on such anecdotal observation and small case studies which have failed to stand up to scientific scrutiny. To date there are no reproducible, blinded, randomized studies utilizing control populations which have demonstrated a benefit to sympathetic blockade in CRPS.

Increased sensitivity of digital vessels to circulating catecholamines, nerve fiber regeneration or incomplete sympathectomy have been postulated to lead to recurrence. Five patients developed Horner's syndrome postoperatively. A portion of the stellate ganglion was intentionally resected in 3 of the 5 patients.

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.

The graph shows an overall shorter survival rate of sympathectomised rats

Chemical sympathectomy was performed by double intraperitoneal administration of 6-hydroxydopamine (6OHDA) 100mg/1 kg. 6OHDA is a neurotoxin used for selective ablation of dopaminergic and noradrenergic neurons. YA cells AH-130 which typically grow as free cells in ascites were injected intraperitoneally in amount of 20 - 25 mil/2 ml.

               

                Four groups of Wistar rats (AnLab, Prague) weighing 150 - 175g were used in the experiment. An absolute control group (8 rats), and a control sympathectomised group (8 rats), a group injected with YA cells (16 rats) and the last group was sympathectomised and injected with YA cells (16 rats).

               

                After a week of acclimatization of rats to conditions of animal room, sympathectomy was performed. One week later, YA cells were applied. The incidence and growth of ascites, and mortality were monitored.

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].

Removal of the clips from the sympathetic trunk does not provide resolution of compensatory sweating

Removal of the clips from the sympathetic trunk does not provide resolution of compensatory sweating in 1 year of observation. T6-9 block does not provide remedy for compensatory hyperhidrosis. Regional abdomino-lumbar iontophoresis seems to be very promising, but further research and followup are mandatory.

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.

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.

A randomized placebo-controlled trial of oxybutynin for the initial treatment of palmar and axillary hyperhidrosis

Palmar and axillary hyperhidrosis improved in >70% of the patients, and 47.8% of those presented great improvement. Plantar hyperhidrosis improved in >90% of the patients. Most patients (65.2%) showed improvements in their quality of life. The side effects were minor, with dry mouth being the most frequent (47.8%).

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.

Endoscopic sympathectomy is not minimally invasive - doing the same operation through a smaller incision is not necessarily less 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].

Endoscopic thoracic sympathectomy remains a fairly controversial procedure

Studies by ETS surgeons have claimed an initial satisfaction rate around 85-95% with at least 2%-19% regretting the surgery and up to 51% of the patients complaining about decreased quality of life. However, at least one study shows a satisfaction rate as low as 28.6.

Most patients report various adverse reactions as a result of the surgery. And, whilst the results of endoscopic thoracic sympathectomy might appear moderately successful in treating hyperhidrosis, there is a high risk of complications.

Along with the normal side effects of surgery, such as pain, bleeding and bruising, the most frequent post surgical complication is ‘compensatory hyperhidrosis’ – where excessive sweating in seen another part of the body as a result, most commonly the lower back or upper thighs.

There is also the potential surgical complication of a pneumothorax, where air becomes trapped between the lung and the internal chest wall, making breathing difficult and painful. Whilst this can be a life-threatening condition, if not too large it generally resolves over time with out further surgical intervention.

Other fairly common complications of endoscopic thoracic sympathectomy include:

         Rhinitis - inflammation of the nose and

         Gustatory sweating - sweating on the face and neck after eating food,

Rarer complications of endoscopic thoracic sympathectomy as a result of nerve damage include:

         Damage to the phrentic nerve. – Phrentic nerve damage can lead to long term shortness of breath, repair of the nerve during the surgery is also possible in some cases..

         Horner’s syndrome, - a condition that causes drooping of the eyelids.

Endoscopic thoracic sympathectomy remains a fairly controversial procedure; with advocates claiming high success rates and minimal complications when performed correctly, whilst opponents report huge variation in post operation satisfaction levels and poor consistency in the surgical procedure as a result of anatomical variations in the sympathetic nerve network between patients and personal preferences between doctors.
