We report our 3-years experience with video-thoracoscopy for pneumothorax. Forty-six endoscopies (34 men, 12 women; mean age 27 +/- 9 years) were performed. Patients were under general anesthesia and intubation was selective. The conventional approach was used, with 3 incisions through which the camera and endoscopic instruments were inserted. Results were good in 39 (84.7%) patients. Pneumothorax recurred in 4 (8.7%) patients during the 3 years of follow-up. Thoracotomy was performed in 3 patients, because of lack of lung expansion in 1, persistent leak in another and encapsulated empyema in the third. Mean hospital stay after surgery was 7.3 days. Video-thoracoscopy can be considered a good therapeutic alternative to thoracotomy in the surgical treatment of patients with pneumothorax.
