Aspiration <i>versus</i> tube drainage in primary spontaneous pneumothorax: a randomised study

This randomised study was designed to compare clinical outcomes for simple aspiration versus tube thoracostomy, in the treatment of the first primary spontaneous pneumothorax (PSP) attack. A randomised trial, comparing simple aspiration with tube thoracostomy, in 137 patients with a first episode of PSP was carried out. Immediate success was obtained in 40 out of the 65 patients (62%) randomly assigned to undergo simple aspiration and in 49 out of the 72 patients (68%) who had been randomly assigned to undergo tube thoracostomy. The 1-week success rates were: 58 (89%) patients in the intention-to-treat simple aspiration group and 63 (88%) patients in the tube thoracostomy group. In the aspiration group, there were more recurrences during the 3-month follow-up period (15 versus 8%), though the difference was not significant. Recurrence rates at 1 and 2 yrs were 16 (22%) and 20 (31%) for patients who had undergone simple aspiration, respectively, and 17 (24%) and 18 (25%) for patients who had undergone tube thoracostomies, respectively. Complications occurred in 5 (7%) patients who had undergone a tube thoracostomy and 1 (2%) patient who had undergone simple aspiration. Analgesia was required in 22 (34%) patients of the simple aspiration group versus 40 (56%) patients of the tube thoracostomy group. These findings suggest that simple aspiration could be an acceptable alternative to tube thoracostomy in the treatment of primary spontaneous pneumothorax.
