Long-term results of thoracic sympathectomy for primary hyperhidrosis

The side effects following thoracic sympathectomy for primary hyperhidrosis include pain and compensatory/ reflex sweating. The aim of the study was the evaluation of the results of the endoscopic sympathicotomy with clips with emphasis on the frequency of side effects following the operation.

Two-hundred-eighty-three patients were qualified to thoracic T3-T4 sympathicotomy with clips. In all cases bilateral procedure in prone position with CO2 insufflation was performed. The subjective intensity of disease was evaluated by VAS scale (0--no sweating; 10--maximal possible sweating) while the recurrence of the sweating in primary localization, intensity and dynamics of compensatory and plantar sweating were evaluated post-operatively. Follow-up data were obtained during office visits 3, 12 and 36 months after surgery. The overall follow-up response was 74.6%.

There was no mortality. Perioperative morbidity included 6 cases of pneumothorax. The mean duration of surgery was 57 minutes bilaterally. The postoperative intercostal pain was present in all patients (100%) with mean duration of 21.88 days but in 72.6% of cases it did not demand any medication as early as 48 hours after surgery. Strong or very strong compensatory sweating was observed in 17.5% of cases 3 months after ETS, in 14.1% after 12 months and in 23.6% after 36 months.

Thoracic sympathicotomy with clips is a safe treatment that provides satisfactory longterm results. The incidence of side-effects (intercostal pain, compensatory sweating) is high and does not change with time in most of the cases.
