Abstract
OBJECTIVES: Although early removal of postoperative chest drains can facilitate postoperative recovery, there are risks of undetected bleeding and a need for re-drainage to treat delayed pulmonary air leaks. In this study, we aimed to prospectively examine the feasibility of tubeless thoracoscopic bullectomy in primary spontaneous pneumothorax (PSP) patients. METHODS: Between January 2021 and November 2021, 30 PSP patients were enrolled in this prospective study. The absence of air leakage was confirmed and radiographic evidence of lung expansion was acquired; the tube was then removed in the operating room. The primary endpoint was postoperative air leakage requiring re-drainage among patients who underwent tube removal in the operating room. The secondary endpoints were postoperative pain (numerical rating scale) on postoperative days (PODs) 1, 7, and 28, morbidity, and postoperative hospitalization time. RESULTS: Four (13.3%) patients were excluded because of underlying pulmonary disease (n = 2) and air leaks (n = 2) detected in the operating room. Chest drainage tubes were removed in the operating room for the remaining 26 patients; none of them required re-drainage. The mean postoperative hospitalization time was 1.2 ± 0.4 days. The mean numerical rating scale scores were 4.2 ± 2 (median: 4.5), 1.6 ± 1.6 (median: 1), and 0.4 ± 0.8 (median: 0) on PODs 1, 7, and 28, respectively. Only one case of hemoptysis occurred as a postoperative complication. CONCLUSIONS: Tubeless thoracoscopic bullectomy for PSP is feasible and may reduce the postoperative hospitalization time; however, it does not significantly reduce pain on POD1.
