The practice of surgical and chemical sympathectomy for neuropathic pain and CRPS is based on very little high quality evidence

Sympathectomy should be used cautiously in clinical practice, in carefully selected patients, and probably only after failure of other treatment options.

Cardiovascular collapse developing during thoracoscopic thoracic sympathectomy

Cardiovascular collapse developing during thoracoscopic thoracic sympathectomy in a patient with essential palmar hyperhidrosis: A case report.

Thoracoscopic thoracic sympathectomy (TTS) is usually a safe and uncomplicated procedure for treating essential palmar hyperhidrosis. However, we report a case of cardiovascular collapse that developed in a healthy patient undergoing TTS. The surgeon performed the left sympathectomy without incident. However, scarcely had an incision been made in the skin of the right chest when the patient developed sinus bradycardia and sudden, severe hypotension. Pulseless ventricular tachycardia occurred immediately thereafter, which rapidly progressed to ventricular fibrillation and cardiovascular collapse. The patient required resuscitation with 200 J of direct current shock defibrillation along with an intravenous injection of epinephrine 1 mg. She recovered without sequelae. We believe the Bezold-Jarisch reflex was triggered by pooling of venous blood and surgical stimuli, and the patient developed cardiovascular collapse as a result.

cervical sympathectomy for sexual dysfunction?

Use of stellate ganglion block for the treatment of sexual dysfunction

If the claims of the hundreds of ETS/ESB surgeons is true, than cervical or thoracic sympathectomy affects a well controlled, and limited area of the upper extremity (the hands only) to 'eliminate the overactive nerves that supply the sweat glands', - then this 'invention' registered by Lipov should be dismissed. 


Lipov here claims to prove systemic effect of the cervical procedure that will influence sexual function. Is he finally asserting what so many patients are saying and so many surgeons keep denying, that:
a: interference with the upper sympathetic chain elicited systemic changes of the nervous system
b: interference with the upper thoracic chain affected (also) sexual function - which was not beneficial to the patient. Indeed, retrograde ejaculation can be found in studies describing adverse effects of sympathectomy.

'Sweating surgery' controversy

There is tremendous controversy surrounding ETS. While prestigious medical boards such as the Society of Thoracic Surgeons fully support it, the National Institutes of Health considers ETS to be a "nerurocardiologic disorder", and NIH studies ETS patients as part of their protocol for autonomic failure. There is much disagreement among ETS surgeons about the best surgical method, opitimal location for nerve destruction, and as to the nature and extent of the consequent side effects. The internet now features many websites run by surgeons extolling the benefits of ETS backed by happy patient testimonials. However, there are also many websites run by disabled ETS victims who complain of severe complications and lack of adequate informed consent. Several online discussion forums are dedicated to the subject of ETS surgery, where both positive and negative patient testimonials abound.

FACTORS CONTRIBUTING TO SYMPATHECTOMY FAILURE

1. Sympathectomy is analogous to the act of killing the messenger. The sympathetic nervous system has the critical job of properly controlling and preserving the circulation in different parts of the body, especially in the extremities. By paralyzing the system, the extremity will be more apt to have disturbance of circulation and is left unprotected from fluctuation in circulation.

Sympathectomy is similar to permanently removing the central heat and air-conditioning system and never replacing it because of malfunction.

Sympathectomy permanently damages the temperature regulatory system. The reason sympathectomy does not cause side effects other than ineffective control of pain as well as impotence and orthostatic hypotension is because it is invariably partial and incomplete.

2. Even after "complete" removal of the sympathetic plexus for the upper or lower extremities, the sympathetic nerves in the wall of the blood vessels are left intact.

3. As shown in Table 6, the most common form (over 80%) of RSD is disuse RSD. In this situation, the sympathetic system is temporarily hyperactive. Proper conservative treatment would prevent any unnecessary invasive surgery (such as sympathectomy) in such patients.

4. Usually the patients that end up needing sympathectomy are the ones who suffer from ephaptic dystrophy. Sympathectomy in such cases cause a classic Cannon phenomenon. This physiological phenomenon refers to the fact that the end organ that is controlled by sympathetic nerve fibers  will become uninhibited in its chemical dysfunction. As a result, even though the sympathetic fibers are not contributing to acetylcholine or become uninhibited with resultant increase of pain input.

In diabetic neuropathy RSD, sympathectomy dramatically relieves the pain for the first 1 to 3 years. Then deafferentation can Cannon phenomenon set in. As a result, invariably by the second to fifth year the patient ends up with a lot more pain. Sympathetic blocks repeated every 6 to 12 months yield similar results.

In patients who have had sympathectomy, thermography shows an increase of temperature  in the focus of ephaptic nerve damage (Cannon phenomenon) with secondary increase of pain and discomfort.

In 70 % compensatory sweating severe, recurrence rates were 15% and 19% at 1 and 2 years after surgery

In T2 and T3 resection, all patients experienced Compensatory Sweating and over 70% of the patients felt it was severe. Even in T2 resection, 90% of patients experienced CS and in 50% of these it was severe. High rates of CS are reported in Asian countries with hot and humid climates.

In T2 resection, recurrence rates were 15% and 19% at 1 and 2 years after surgery.It was not rare for a patient to experience recurrence more than 3 years after surgery.

bradycardia and other cardiac complications are common side effects?

The most common side effects of sympathectomy are compensatory sweating, gustatory sweating and cardiac changes including decreasing heart rate, systolic-diastolic and mean arterial pressure. The mechanism of bradycardia and other cardiac complications that develop after thoracic sympathectomy are still unclear.

"It is a lie that sympatholysis may specifically cure patients

with unqualified "reflex sympathetic dystrophy". This was already stated by the father of sympathectomy, Rene Leriche, more than half a century ago.
...it is not an error, but a lie. While conceptual errors are not only forgivable but natural to inexact medical science, lies, particularly when entrepreneurially inspired are condemnable and call for a peer intervention.

impairment of autoregulation after unilateral cervical sympathectomy

Although these findings argued against a neurogenic mechanism, James at al. (1969) reported impairment impairment of autoregulation after unilateral cervical sympathectomy in the babbon. Gotoh et al. (1971/1972) observed impairment of autoregulation in patients with the Shy-Drager syndrome.
It was concluded that the autonomic nervous system plays an important role in the mechanism of autoregulation of CBF and that his mechanism is independent of the chemical control of the cerebral vessels. This was confirmed by direct observation of the pial vessels in cats, where separate sites of action in the vascular tree for autoregulation and chemical control were demonstrated; the autoregulatory reaction was located in pial arteries with a diameter larger than 50 μ, and the reaction to carbon dioxide in pial arteries of smaller diameter (Gotoh et al. 1975).
They concluded that the arteries operating in autoregualtin were the larger ones with the dense innervation, while the smaller arteries with sparse innervation were involved in chemical control.
Coronna and Plum (1973) demonstrated the absence of CBF autoregulation in a patient with a Shy-Drager syndrome who had a postganglionic denervation....

Gotoh et al (1979) subsequently showed that autoregulation in patients with this syndrome was impaired irrespective of the localization of the damage to the cervical sympathetic nervous system (preganglionic, central, postganglionic) as judged by the eye instillation test.

unavoidable side effects and unforeseeable and unacceptable complications after sympathectomy

Most of the difficulties associated with hyperhidrosis surgery are due to unavoidable side effects and unforeseeable and unacceptable complications. Careful patient selection is important before surgery so surgeons can avoid some of these pitfalls. Patients should also be fully informed of all potential side effects and complications before surgical treatment.

There is potentially a number of safety issues associated with this procedure

"A lack of high quality randomised trial evidence on ETS means that it is difficult to make a judgment on the safety and effectiveness of this technique. There is potentially a number of safety issues associated with this procedure. ASERNIP-s suggests that a full systematic review including all available comparative and case series information, together with clinical inpuut, should be undertaken to provide up-to-date and comprehensive assessment of the safety and effectiveness of ETS."

Reported success stories on ETS are "prone to bias and have significant methodological problems"

Australian Review of ETS surgery - 2001
The four case series were not critically appraised because they are prone to bias and have significant methodological problems. These studies represent level IV evidence according to the NHMRC criteria and one should not draw firm conclusions from their findings.

To date, the benefits or side effects associated with endoscopic thoracic sympathectomy for treating facial blushing have not been properly evaluated and reported.

Further research using a well-designed controlled trial is warranted to assess the efficacy of endoscopic thoracic sympathectomy for treating facial blushing.

UK Review of ETS surgery
We did not identify any controlled trials or cohort studies. The evidence about effectiveness, based on three case series, was therefore very limited. The main weakness of these studies was their lack of a comparison group and their resulting inability to exclude a placebo response to surgery. In addition, the methods of assessing outcome were poorly described and not validated, and the range of outcomes assessed was limited. The studies provided very limited evidence that sympathectomy improves blushing. Side effects were common.

inhibition of sympathetic activity and a possible impairment of endothelial function.

Alterations in skin microcirculation induced by brachial plexus block can be evaluated by wavelet transform of the laser Doppler flowmetry signal. Brachial plexus block reduces the oscillatory components within the 0.0095- to 0.021- and 0.021- to 0.052-Hz intervals of the perfusion signal. These alterations are related to inhibition of sympathetic activity and a possible impairment of endothelial function.

in one-lung ventilation (OLV), shunt fraction increases, oxygenation is impaired, and hypoxemia may occur

When switching from two-lung to one-lung ventilation (OLV), shunt fraction increases, oxygenation is impaired, and hypoxemia may occur. Hypoxemia during OLV may be predicted from measurements of lung function, distribution of perfusion between the lungs, whether the right or the left lung is ventilated, and whether the operation will be performed in the supine or in the lateral decubitus position. Hypoxemia during OLV may be prevented by applying a ventilation strategy that avoids alveolar collapse while minimally impairing perfusion of the dependent lung. Choice of anesthesia does not influence oxygenation during clinical OLV. Hypoxemia during OLV may be treated symptomatically by increasing inspired fraction of oxygen, by ventilating, or by using continuous positive airway pressure in the nonventilated lung. Hypoxemia during OLV may be treated causally by correcting the position of the double-lumen tube, clearing the main bronchi of the ventilated lung from secretions, and improving the ventilation strategy.

Lack of disclosure to ETS patients is unethical and would be criminal in a just society

It is the doctor's moral and ethical duty to provide you with full and honest disclosure of the facts prior to surgery. The whole doctrine of informed consent is to prevent patients from having to realize they made a mistake in hindsight. You shouldn't have had to find out from a former patient's wife that the surgery would cause drenching sweating on your back. It was Garza's job to do that. He completely lied to you regarding the supposed reversibility. Anyone who goes through medical school knows that can't crush a nerve with a metal clamp, remove it later and have the nerve return to normal functioning.

Although it is not possible to predict exactly what will occur in each individual case, there is nearly 100 years of published scientific and medical research available on the effects of sympathectomy. That research paints a very different picture of the effects of this surgery than the one presented to patients considering this surgery. That's the issue. Generally, they lie and tell patients that CS is inconsequential in all but a tiny fraction of cases and simply fail to disclose a huge number of verified adverse effects of the surgery. They take advantage of the patient's ignorance on medical matter. It's unethical and would be criminal in a just society.

In short, you do have a way of knowing what will likely occur as a result of the surgery before you have it done. All the information necessary to make an informed decision exists. It's just not getting to patients.

the pineal capability of producing antigonadal substance is suppressed by cervical ganglionectomy

Pineal glands of male hamsters 8 weeks after removal of both eyes or both superior cervical ganglia and those of untreated animals were studied by electron microscopy. In the blinded hamsters the reproductive organs were remarkably involuted, whereas the pinealocytes enlarged and were characterized by a tremendous hypertrophy of the smoothsurfaced endoplasmic reticulum, in the mesh of which some dense cored vesicles were distributed. In contrast the pinealocytes of ganglionectomized hamsters atrophied and were noted by a large number of lysosomes and sparsity of the agranular reticulum, the testes being significantly larger than the controls. The findings were interpreted to be compatible with the view that the pineal capability of producing antigonadal substance is augmented by blinding and is suppressed by cervical ganglionectomy due to the impairment of normal functioning of the pineal by denervation.

Haematological changes during stress abolished by sympathectomy

To study haematological effects of emotional stress, blood samples were obtained from 29 healthy, normotensive, non-smoking males aged 20–34 years before, during and after 10 min of mental arithmetic. There were significant increases in pheripheral blood cell count, haemoglobin concentration, and haematocrit in response to mental stress. Parallel to these changes significant increases in heart rate, and systolic and diastolic blood pressure were observed. The relative increments of leucocyte (8%) and platelet (3·5%) count were significantly higher than the increase in haemoglobin concentration (2%). There was a significant positive correlation between the blood pressure increase and the mobilization of leucocytes, whereas the increase in erythrocyte count, haemoglobin concentration, and haematocrit showed significant positive correlations with heart rate reactivity. It is concluded that mental stress causes an increase in leucocyte and platelet count that could not solely be accounted for by the concurrent haemoconcentration.

The emotional leucocytosis observed in dogs has been claimed to be neurogenic in origin, since sympathectomy abolished the rise in leucocyte count (Garrey & Bryan, 19 3 5).

ETS can rarely, if ever, be used effectively to treat hyperhidrosis
