(1) Objective To review our experience with endoscopic thoracic sympathectomy.

(2) Conclusions Endoscopic thoracic sympathectomy is simple and safe, procedure.

(3) In sympathectomy group , the left paravertebral sympathetic trunk was resected from L1 to the most caudal level by abdominal approach .

(4) In Norway maximum fifty patients have the sympathectomy each year. What is your point of view?

(5) Sympathectomy consisted of sympathetic chain at the T 2 level and any accessory nerves present.

(6) Results: The slow twitch muscle fibers increased after sympathectomy. it is more significant in SCS group.

(7) Successful sympathectomy achieved in 99 % of palmar surfaces without recurrence.

(8) Objective : To investigate the effects of chemical lumbar sympathectomy combined femoral artery puncture on thromboangiitis obliterans.

(9) In the treatment group, 9 cases of palmar hyperhidrosis were treated by thoracic sympathectomy(Sentencedict), 1 case of pericardial liparomphalus was resected.

(10) Objective:To provide an optimal secure method for procedure of sympathectomy through observing microanatomy of the upper thoracic sympathetic trunk and its adjacent structures.

(11) Objective To evaluate the therapeutic result of endoscopic thoracic sympathectomy for the treatment hyperhidrosis.

(12) Methods 58 patients with hyperhidrosis treated with endoscopic thoracic sympathectomy were reviewed retrospectively.
