Objective: Pleurodesis is among several treatment strategies for postoperative alveolo-pleural fistula (APF) after lung resection. Accordingly, the present study aimed to determine the influence of pleurodesis on postoperative pulmonary function. Methods: Patients who underwent anatomical segmentectomy between January 2009 and March 2020 and pulmonary function tests 6 and 12 months after initial surgery were included in this study. Differences in pulmonary function decline between patients who did and did not undergo pleurodesis were compared. Results: Among the 319 patients included, 39 (12.2%) underwent pleurodesis. Among patients who did not receive pleurodesis, there were no difference in decline of vital capacity at 6 months (−13.7% ± 1.1% vs −11.2% ± 0.7%; P = .063) and 12 months (−10.7% ± 1.3% vs −9.5% ± 0.7%; P = .391) after surgery between patients who had APF on postoperative day 2 and those who did not. Patients who received pleurodesis had a significantly larger decline in vital capacity at 6 months (−19.4% ± 2.4% vs −13.7% ± 1.1%; P = .015) and 12 months (−16.2% ± 1.6% vs −10.7% ± 1.3%; P = .010) after surgery compared with those who had APF on postoperative day 2 and did not receive pleurodesis. There were no significant differences in decline of forced expiratory volume in 1 second. Conclusions: Pleurodesis negatively influenced postoperative vital capacity after lung segmentectomy. Although the clinical influence of this is unknown, careful consideration is needed before performing pleurodesis given its potential influence on postoperative pulmonary function.
