Treatment of primary spontaneous pneumothorax by videothoracoscopic talc pleurodesis under local anesthesia: a review of 133 procedures.

AIM: To review our experience of treatment of primary spontaneous pneumothorax by videothoracoscopic talc pleurodesis. METHODS: From 2000 to 2008, 124 consecutive patients with primary spontaneous pneumothorax were operated; 105 were men (84.7%) and 19 were women (15.3%) with a mean age of 26.6 years (range 17-46 years). RESULTS: No mortality was recorded. Staging according to Vanderschueren's classification was as follows: stage I, 61 patients (45.9%); stage II, 39 patients (29.3%); stage III, 31 patients (23.3%); stage IV, two patients (1.5%). The overall rate of complications was 9% (12/133), corresponding to prolonged air leak in 9(6.7%) patients and hemothorax in 3(2.2%) patients. Four patients (3%) had recurrence requiring reoperation. There were no episodes of acute respiratory failure, pneumonia or subcutaneous emphysema following talc pleurodesis. CONCLUSIONS: Thoracoscopic pleural talc pleurodesis as a treatment for recurrent pneumothorax is easy, safe, and rapid, and causes minimal morbidity and mortality.

UNLABELLED: The autonomic nervous system adjusts sweating on the body's skin surface. The skin areas corresponding to the various sympathetic ganglia are not yet clearly defined. The purpose of this study was to define the skin areas corresponding to the T2 and T3 sympathetic ganglia. METHODS AND MATERIALS: We performed bilateral thoracic sympathicolysis endoscopically on the T2 and T3 ganglia of 50 patients with primary hyperhidrosis. All answered a questionnaire before surgery and at least two months later. The questionnaire asked about sweating at different points, but in order to estimate the cutaneous projection of T2 and T3 we only analyzed anhidrotic regions. RESULTS: Denervation resulted in anhidrotic hands (98.11%); axillas (73.58%); arms (39.62%); forehead (20.75%); chin, cheeks, neck and the nape of the neck (16.98%); sides of the chest (13.2%); front of the chest (7.54%); and back (1.88%). CONCLUSIONS: The territory influenced by the T2 and T3 sympathetic ganglia is more extensive than has been described by classical anatomical studies. The cutaneous area innervated by the sympathetic T2 and T3 ganglia extends to zones influenced by T1 in up to 20.75% of patients with primary hyperhidrosis.
