[Perioperative Management for Air Leakage, Atelectasis, and Pneumonia in Patients Undergoing Lung Resection].

Thoracic surgeons often encounter postoperative air leakage, atelectasis, and pneumonia as common complications of lung resection. Mostly, those are managed and treated properly, which results in avoiding serious outcomes. However, some clinical conditions manifesting initially as common complications could become severe unless an early correct differential diagnosis is made. Regarding air leakage, we summarized intraoperative techniques for pulmonary fistula and pleurodesis as postoperative treatment. Concerning atelectasis, in addition to management for obstructive atelectasis due to bronchial secretion, we described the adaptive displacement of the middle lobe after right upper lobectomy and tips for diagnosis and management of bronchial kinking and/or lobar torsion of the middle lobe. Regarding postoperative pneumonia, we emphasized smoking cessation and overviewed standard management for chronic obstructive pulmonary disease by bronchodilator as preoperative management. Moreover, we summarized standard treatment for hospital-acquired pneumonia and emphasized the importance of differential diagnosis if the initial empiric antibiotic therapy failed because some interstitial pulmonary diseases, such as organizing pneumonia and drug-induced lung injury, may mimic bacterial pneumonia.
