[Thoracic sympathectomy by thoracoscopy. Apropos of 15 cases].
Thoracic sympathectomy is achieved using the trans-axillary route during the course of a thoracotomy. The indications are Raynaud's phenomenon, digital arteriopathy, and hyperhidrosis. Alongside the surgical approach in theory it is possible to use a thoracoscopic approach for a thoracic sympathectomy, to achieve a physico-chemical destruction, we have studied this possibility using this technique.


METHODS
Thoracoscopy is achieved under local anaesthetic after creating a pneumothorax. The approach is through the 2nd intercostal space in the mid-clavicular line. Anaesthesia of the 2nd sympathetic ganglion is achieved, the ganglion is destroyed by injection of 8 c.c's of Phenol. 15 patients were treated (15 to 7). The presented with palmar hyperhidrosis (7), digital arteriopathy (6) or Raynaud's syndrome (2).


RESULTS
The first 5 patients were failures which led to a more precise technique. Overall we observed 8 favourable results. If we exclude the first 5 cases we achieved 8 favourable results and 2 failures. The approach to the 2nd sympathetic ganglion using the thoracoscope is not always possible: the vision may be obscured. When it is possible phenolization may yield excellent results comparable to those of surgical sympathectomy.


CONCLUSIONS
Palmar hyperhidrosis for which we have obtained the best results seems to us to be an extra indication of this technique which enables a cure at the price of a relatively simple procedure and a brief period of hospital stay.
