Prolonged or persistent air leak (PAL) is one of the most common complications in patients after surgery on the lung parenchyma. Air leaks typically originate from alveolar-pleural fistulas, which can result from surgical manipulation of the lung parenchyma or the bronchial stump after procedures such as lobectomy. Key risk factors for PAL include extensive lung resections such as lobectomy, presence of pleural adhesions, incomplete interlobar fissures, chronic obstructive pulmonary disease (COPD), asthma, emphysema, advanced age, and reduced preoperative lung function, particularly low preoperative FEV1 values. PAL necessitates extended pleural drainage, leading to significant patient discomfort, pain, and substantial limitations in early postoperative rehabilitation. In patients with pre-existing pulmonary conditions like bronchial asthma or COPD, PAL can markedly worsen clinical stat
