"Sympathectomy is a destructive procedure that interrupts the sympathetic nervous system"

Cervico-thoracic or lumbar sympathectomy for neuropathic pain | Cochrane Summaries: "Sympathectomy is a destructive procedure that interrupts the sympathetic nervous system. Chemical sympathectomies use alcohol or phenol injections to destroy sympathetic nervous tissue (the so-called "sympathetic chain" of nerve ganglia). Surgical ablation can be performed by open removal or electrocoagulation (destruction of tissue with high-frequency electrical current) of the sympathetic chain, or by minimally invasive procedures using thermal or laser interruption. Nerve regeneration commonly occurs following both surgical or chemical ablation, but may take longer with surgical ablation.

This systematic review found only one small study (20 participants) of good methodological quality, which reported no significant difference between surgical and chemical sympathectomy for relieving neuropathic pain. Potentially serious complications of sympathectomy are well documented in the literature, and one (neuralgia) occurred in this study.

The practice of sympathectomy for treating neuropathic pain is based on very weak evidence. Furthermore, complications of the procedure may be significant."

"our advice to patients must reflect the true potential outcomes"

Dear Editor,

I refer to the article on palmar hyperhidrosis by Dr Sanjay Sharma (Managing palmar hyperhidrosis, March). I feel that the adverse effects [of thoracoscopic sympathectomy] are understated by my colleague. For example, compensatory hyperhidrosis is common, and can be disabling, leading to regret about the procedure in some patients (up to 51% in one review). Reversal of the procedure is difficult and requires sural nerve transplant if the sympathetic chain is removed.

The procedure can be effective and worthwhile, but our advice to patients must reflect the true potential outcomes.

Sympathectomy, ganglionopathies and myelopathies produce such pattern

Segmental Anhidrosis

This pattern occurs when a large, contiguous body area of sweat loss with sharply demarcated borders conforming to sympathetic or somatic dermatomes are present.

Sympathectomy, ganglionopathies and myelopathies produces such pattern. When borders are not well defined and anhidrosis not contiguous, a regional pattern is said to exist. Both postganglionic and preganglionic lesions may produce these distributions. (p.557)

ETS "highlighted the disparity between what is known in practice and what appears in the literature"

The March 2004 edition was quite outstanding, with an excellent editorial reminding the reader that only good results are published. The review on thoracoscopic sympathectomy highlighted the disparity between what is known in practice and what appears in the literature.

‘Know Your Results’, the topic of the ASGBI Annual Scientific Meeting, is of outstanding importance; what is more, the surgeon has to go on knowing his/her results to ensure standards of practice do not slip.

The Journal appreciates comments and criticism and the correspondence column remains a crucial part of the BJS in its interaction between editors and reader. It is also part of the scientific process.

A more robust and incisive criticism of articles known to be flawed would prevent the retractions that have recently been published in the Lancet.

Sympathectomy results in a significant interference in regulatory processes of the body

"ESB (whether as ETS as ETSC or ELS) generally represents a substantial interference in regulatory processes of the body. Therefore decision for this operation requires that previously conservative treatments were made. An ESB is therefore at the end of a treatment history, and never at the beginning."

Dr. Christoph H. Schick, ETS surgeon, President of the International Society of Sympathetic Surgery (ISSS)

our ignorance of the of the effect of sympathetic ablation

"These observations further emphasize our ignorance of the mechanisms responsible for primary hyperhidrosis and of the effect of sympathetic ablation on the function of the remaining sympathetic system."

"Only investigators who deviate from accepted standards innovate and thus advance science. Obviously, such deviations may also result in disasters;"

Endoscopic Lumbar Sympathectomy Following Thoracic Sympathectomy in Patients with Palmoplantar Hyperhidrosis

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].
