Non-stapling thoracoscopic surgery for spontaneous pneumothorax in young patients.

OBJECTIVES: Spontaneous pneumothorax in young patients has a high recurrence rate, even after surgical treatment, and bulla neogenesis around stapled lesions has been reported as a cause of postoperative recurrence. We investigate the clinical safety and long-term outcome of non-stapling thoracoscopic surgery for spontaneous pneumothorax in young patients. METHODS: Twenty-seven non-stapling thoracoscopic surgeries for pneumothorax in 24 patients younger than 25 years were retrospectively reviewed. The non-stapling surgical techniques used to treat bullae included thoracoscopic suture plication, soft-coagulation, covering, and ligation. Long-term follow-up was conducted by telephone or by a mailed questionnaire. RESULTS: In 22 (81.5%) operations, suture plication, soft-coagulation, and covering procedures were used in combination. The median number of bullae treated in one operation was 2 (range, 0-6). The median operative time was 97 min, and the median postoperative drainage and postoperative hospital stay periods were 1 and 3 days, respectively. No complications of grade 2 or higher were observed. Patients were followed for at least 30 (median, 37) months. The postoperative recurrence rate was 3.7%, with one case of recurrence due to bulla neogenesis at a distant site. CONCLUSION: Non-stapling thoracoscopic surgery with covering procedure for pneumothorax in young patients might reduce postoperative recurrence.
