"How to Review Post-lobectomy Posteroanterior Chest Radiographs".

Lung cancer is currently the most common malignancy in the world. A lobectomy is the gold standard of care for most patients with an operable lung cancer and accounts for 60-70% of lung resection. The chest radiograph may appear normal after a lobectomy, particularly in uncomplicated cases. However, lobectomy usually leaves the surgical staples at the bronchial stump and causes various changes in the intra- and extrapulmonary thoracic structures on plain radiographs. These changes may differ according to the resected lobe. We retrospectively evaluated the plain radiographic appearances of the post-lobectomy chest, free of postoperative complications or recurrent/metastatic lung cancer. Based on our observations, the changes that occur in pulmonary and extrapulmonary anatomy can differ according to the resected lobe. Recognition of these changes will make it easier to identify which lobe has been removed surgically.
