BACKGROUND: When a clinical context is indeterminate for idiopathic pulmonary fibrosis (IPF), or a chest high-resolution computed tomography (HRCT) pattern is not indicative of typical or probable usual interstitial pneumonia (UIP) in patients with interstitial lung disease (ILD), surgical lung biopsy should be considered to make a confident diagnosis on the basis of multidisciplinary diagnosis (MDD). AIM: The aim of this study was to evaluate the role and safety of video-assisted thoracoscopic surgery (VATS) in patients with ILD. METHODS: A total of 143 patients with ILD underwent VATS at Toho University Medical Center Omori Hospital between March 2004 and April 2017. We conducted a retrospective study on the usefulness and safety of VATS in the diagnosis of ILD under MDD. RESULTS: The 30-day mortality was 0%. The postoperative complication rate was 12.6%, which included 5 cases of pneumothorax after discharge (3.5%), 4 cases of prolonged air leakage (2.8%), and 2 cases of acute exacerbation (1.4%). Three of 9 cases (33.3%) complicated by pneumothorax after discharge or prolonged air leakage were resected specimens of pleuroparenchymal fibroelastosis (PPFE). Two patients had acute exacerbation, who were ultimately diagnosed as having idiopathic unclassifiable IP and had histologically significant irregular dense fibrosis and numerous fibroblastic foci. The comparison between chest HRCT and histopathological findings revealed 55 cases of possible UIP [UIP (45%), NSIP (25%), and unclassifiable IP (29%)] and 21 cases of inconsistent with UIP [UIP (10%), NSIP (33%), organizing pneumonia (10%), unclassifiable IP (24%), and PPFE (24%)]. CONCLUSION: VATS can be safely performed to obtain a confident diagnosis for appropriate treatment strategies in patients with ILD. Copyright:
