[Short and long term follow-up of spontaneous pneumothorax treated using video-thoracoscopy].

The outcome of video-assisted thoracoscopic treatment of spontaneous pneumothorax was analyzed. Eighty-three procedures were performed in 79 patients (58 men, 21 women: mean age 28.3 years, range 16 to 76 years). The reasons for intervention were recurring pneumothorax in 53 patients, contralateral pneumothorax in 10 (one of whom was treated on both sides), bilateral involvement in 3, and persistent air leakage in 13. Seven patients (8.4%) also required open thoracotomy. In 72 (88%) of the remaining 76 procedures, only video thoracoscopy was used. Three patients (3.6%) underwent video-assisted thoracotomy. Mean postoperative hospital stay was 5.1 days (2 to 24 days). No related deaths occurred but surgical complications were reported for 3 (3.9%). Significant postoperative complications developed in 9 cases (11.8%). One patient with prolonged air leakage underwent a second procedure, video-assisted thoracotomy, 12 days after the first intervention. Seventy-one of the 72 patients received follow-up examinations, with a mean follow-up period of 28.1 months (range 54 days to 54 months). Three recurrences (3.9%) were recorded but there were no cases of chronic pain requiring analgesia. We conclude that video thoracoscopy is an effective approach, with the advantage of being minimally invasive. We therefore believe it should be the procedure of choice, once improved morbidity and recurrence rates are observed, as these factors are influenced by the learning curve.
