ObjectivesTo evaluate the efficacy of the chest tube drainage (CTD) and the needle aspiration (NA) in the treatment of primary Spontaneous pneumothorax (SP).MethodsIn a randomized controlled trial, seventy patients suffering SP were divided equally into two subgroups, as follows: (A) CTD and (B) NA. The immediate and one-week rate of the treatments was the primary endpoints. Postoperative complications, length of hospital stay and incidence of pneumothorax recurrence during one-year follow up were also recorded.ResultsThe immediate success of treatment was 68.5% and 54.2% of patients in CTD and NA groups, respectively that showed no significant difference between study groups (P: 0.16). The complete lung expansion after one week observed in 32 (91.4%) of NA group and 33 (94.2%) patients in CTD group (P: 0.5). Pneumothorax recurrence was detected in 13 patients (4 in NA and 9 in CTD group) (P: 0.11). Mean pain intensity was significantly lower in the NA group at the first hour after the procedure, the first postoperative day and the first week after the intervention (P< 0.001).ConclusionNeedle aspiration (NA) can be applied as a first step treatment in patients with primary SP, considering its advantages.
