Video-assisted thoracic surgery versus pleural drainage in the management of the first episode of primary spontaneous pneumothorax

BackgroundThe aim of the study was to analyze the cost-effectiveness outcomes of video-assisted thoracic surgery (VATS) in the treatment of primary spontaneous pneumothorax (PSP), comparing the minimally invasive procedure with pleural drainage (PD).MethodsBetween July 2006 and October 2012, we treated 122 patients with a first episode of PSP by VATS (61 patients) or pleural drainage (61 patients). We established the relationship between costs and quality-adjusted life (QAL) for both techniques.ResultsThe total cost per patient of minimally invasive procedure was more advantageous than that of chest tube (€2,422.96 vs €4,855.12). The QAL expectancy of VATS was longer than that of PD (57.00 vs 40.80 at 60 months). The QAL year of VATS (.32 at 1st year and .25 at 5th year) was better than that of PD. Incremental cost-effectiveness ratio of VATS versus PD was between €7,600.00 (1st year) and €10,045.00 (5th year), remaining well below the threshold of acceptability.ConclusionVATS as the first-line treatment for PSP allowed low morbidity, short hospitalization, and excellent quality of life.
