Subxiphoid single-incision thoracoscopic bilateral ablative sympathectomy for hyperhidrosis.

We describe the first case of severe palmar hyperhidrosis treated with single-incision subxiphoid thoracoscopic ablative sympathectomy, bilaterally, at T3 level. The single-incision subxiphoid thoracoscopic approach required only a 2-cm incision in the upper abdomen. In addition, the technique does not cause postoperative intercostal neuropathy and postoperative pain is minimal as the intercostal space is bypassed. Total operative time was ∼60 min and the volume of blood loss was 10 ml. The patient was discharged from the hospital the next day with complete remission of her symptoms. Excess palmar sweating released after operation and there was no compensatory sweating after a 6-month follow-up.
