Association between preoperative antifungal therapy and postoperative complications in patients with pulmonary aspergilloma: a national database study in Japan.

Abstract

Postoperative complications of pulmonary resection in patients with pulmonary aspergilloma are common. Preoperative antifungal therapy is a perioperative management strategy to reduce postoperative complications; however, the benefit of the treatment remains controversial. A retrospective cohort study was conducted using data from the Diagnosis Procedure Combination database (July 2010-March 2021), a national inpatient database in Japan. Patients with pulmonary aspergilloma with or without chronic necrotizing pulmonary aspergillosis who underwent pulmonary resection were identified and divided into two groups based on whether they received preoperative antifungal therapy. Propensity-score overlap weighting was performed to compare the occurrence of composite postoperative complications and postoperative length of hospital stay between the two groups. We identified 98 patients with pulmonary aspergilloma who received preoperative antifungal therapy and 399 patients who did not. After propensity-score overlap weighting, the preoperative antifungal therapy group had a significantly lower proportion of composite postoperative complications than the non-preoperative antifungal therapy group (6.8% vs. 14.2%, P=0.038). There was no significant difference in postoperative length of stay between the groups with and without preoperative antifungal therapy (median 14.6 vs. 15.8 days, P=0.41). Preoperative antifungal therapy was associated with a reduction in postoperative complications in patients with pulmonary aspergilloma. Preoperative treatment with antifungals may be beneficial in reducing the risk of postoperative complications in patients with pulmonary aspergilloma undergoing pulmonary resection.
