Bullae Ablation in Primary Spontaneous Pneumothorax

The benefit of bullae ablation for the management of primary spontaneous pneumothorax (PSP) has been established. However, various modalities for bullae ablation have been reported from different centers. The present study aimed to assess whether endoloop ligation of bullae was as effective as staple bullectomy for preventing the recurrence of pneumothorax. Between January 1993 and December 2003, 226 patients (203 men and 23 women) with PSP were recorded and retrospectively reviewed. One hundred thirty (57.5%) patients were treated with endoloop ligation of bullae and the other 96 (42.5%) were treated with staple bullectomy. Mechanical abrasion was performed in all patients after bullae ablation. The recurrence rate of pneumothorax was 6.2% (8 patients) in the endoloop ligation group and 17.7% (17 patients) in the staple bullectomy group (p = 0.006). The postoperative complication rate was 14.6 and 20.8% in the endoloop ligation and staple bullectomy groups, respectively (p = 0.221). The long-term chest discomfort rate after endoloop ligation and staple bullectomy was 14.6 and 13.5%, respectively (p = 0.819) Endoloop ligation of bullae is as effective as mechanical staple bullectomy for the management of bullae in primary spontaneous pneumothorax.
