Abstract
BACKGROUND: The aim of this study was to find out whether thoracoscopic bullectomy with pleural abrasion (BLPA) could lower the recurrence ratio in primary spontaneous pneumothorax (PSP) patients compared with bullectomy alone. METHODS: All PSP patients who underwent video assisted thoracoscopy (VATS) bullectomy (120 bullectomy cases) or BLPA (225 BLPA cases) in our department between 2008.1 and 2013.12 were retrospectively reviewed. Clinical data, perioperative data, and follow-up information were collected. Propensity score analysis was used in balancing preoperative factors between groups. RESULTS: Three hundred and forty five patients (283 men and 62 women) with an average age of 27 (27.32±11.41) years old underwent 120 bullectomy and 225 BLPA in this study. There was no mortality or significant complication in both groups. More postoperative drainage (1,170.66±904.02 vs. 528.38±491.49, P<0.01), longer chest tube removal days (6.59±4.29 vs. 4.76±2.67, P<0.01), and more medical cost (4,703.86±1,526.31 vs. 4,204.64±1,203.90, P<0.01) were observed in BLPA group. Significant difference (P=0.02) existed in recurrence rate between BLPA group (3/225, 1.3%) and bullectomy group (7/120, 5.8%). After propensity score match, 114 patients were included in both bullectomy and BLPA groups. More postoperative drainage (1,280.18±1,071.04 vs. 523.55±484.79, P<0.01), longer chest tube removal days (6.53±4.16 vs. 4.69±2.63, P<0.01), and more medical cost (4,700.69±1,591.56 vs. 4,211.45±1,207.7, P<0.01) were observed in BLPA group. There was no significant recurrence difference between BLPA group and bullectomy group (2.6% vs. 5.3%, P=0.30). CONCLUSIONS: Compared with bullectomy, BLPA could provide similar recurrence for PSP patients, but at the price of longer operation days, longer chest tube removal days, and more medical cost, and should not be performed in PSP patients.
