[The indications for and results of video thoracoscopic sympathectomy].

BACKGROUND AND

OBJECTIVES

Thoracoscopic sympathectomy, for years an effective way to treat mainly palmar and axilla hyperhidrosis, experienced a revival since the application of the principles of minimally invasive surgery. We report the personal experiences of three surgeons with this technique, as well as patients' view of the outcome.

PATIENTS AND

METHODS

Between January 1990 and November 1997, 73 procedures were performed in 43 patients (23 males, 20 females, mean age 38.1 years, range 15-82 years), and the outcome was prospectively studied. Palmar hyperhidrosis without axilla symptoms was the indication for the operation in 27 patients (54 sympathectomies), Raynaud's syndrome in 15 (18 sympathectomies), and causalgia in one. Thoracic ganglia 2-4 were always completely resected. Perioperative morbidity as well as patient satisfaction in the long-term course (standardized interview) 25.8 (1-77) months postoperatively were assessed.

RESULTS

The complication rate in all 73 sympathectomies was 8.2%. Only two severe incidents were observed: in one patient intermittent Horner's syndrome (1.4%) occurred, and in another severe bleeding required conversion to open surgery (1.4%). Both complications occurred in the early study phase. The initial success rate in all 27 patients with hyperhidrosis was 100%. In 30% of these cases a mild partial relapse was observed, which did not interfere with their daily activities. 53% of the patients reported compensatory and 23% gustatory sweating. 9% would have refused the operation, had they known these side effects. In all patients with Raynaud's disease the ulcerations healed completely. At the time of the interview, two patients (13%) complained of painless relapses. They too stated that they had refused the operation, if they had known about the relapses.

CONCLUSIONS

Even in the longer-term course, thoracoscopic sympathectomy is rated subjectively successful by 93% of patients after treatment of hyperhidrosis of the upper extremities, and by 87% of patients after treatment of Raynaud's disease, despite some untoward effects and partial relapses.
