post-sympathectomy neuralgia is frequent - reported incidence between 15% to 50%

Surgical sympathectomy has a long heritage for the treatment of peripheral vascular disease and various chronic pain problems.

Despite concerns expressed as long ago as 1942 about the efficacy of surgical sympathectomy for the management of non-cancer pain, the procedure was enthusiastically pursued for the management of reflex sympathetic dystrophy or complex regional pain syndrome (CRPS), migraine, dysmenorrhea, epilepsy, chronic pancreatitis, postherpetic neuralgia of the trigeminal nerve, postdiscectomy syndrome, and phantom limb pain. However, systematic reviews have found no tangible evidence supportive of sympathectomy for the management of neuropathic pain. Furthermore, postsympathectomy neuralgia is a common complaint with a reported incidence between 15% to 50%.

As surgery is often mentioned as a cause of CRPS, it is somewhat illogical to consider surgery as an effective treatment. Nonetheless, surgical sympathectomy has a long anecdotal history in the treatment of RSD, and more recently endoscopic and radiofrequency sympathectomy has been tried.

"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].
