Necessity of Multi-Step Surgical Treatment for Patients with Interstitial Lung Disease and a Pneumothorax

Purpose: A pneumothorax occurs in 3%–8% of patients with idiopathic pulmonary fibrosis. A pneumothorax may predict a poor outcome in patients with interstitial lung disease (ILD), and it is difficult to treat patients with ILD and a pneumothorax. Patients and Methods: We retrospectively studied data from all 12 patients with ILD and a pneumothorax who underwent surgical treatment at Toho University Omori Medical Center Hospital between 2009 and 2021. Results: Of the 12 patients, 2 had home oxygen therapy preoperatively and were classified with grade IV interstitial pneumonia (IP). Six patients had preoperative pleurodesis and two had postoperative one using auto-blood. Three patients (25%) had multi-step surgery ≥2, and 5 patients had surgical resection of bullae. No patients had postoperative acute exacerbations and all were discharged from the hospital in a stable condition. The 5-year overall survival rate for all patients was 70.0%. The median survival time was not reached. One patient with unclassified IP was doing well 116 months after surgery. Conclusion: Patients with ILD and a pneumothorax were shown to require multi-step surgical treatment and can anticipate long-term survival.
