Management of spontaneous pneumothorax: a mini-review on its latest evidence.

Abstract

Spontaneous pneumothorax usually presents as a medical emergency and requires prompt attention and treatment. In patients with underlying lung diseases, it is often associated with prolonged hospitalization, persistent air leak and also a high rate of recurrence. It brings considerable clinical burden to patients and therefore advancement of spontaneous pneumothorax management is eagerly anticipated. In recent years, conservative approach with avoidance of invasive treatment has risen to be a main consideration for primary spontaneous pneumothorax (PSP) patients who are clinically stable with minimal symptoms. The body of evidence in secondary spontaneous pneumothorax (SSP) group is less robust compared with that in PSP group. Non-surgical treatment in SSP is becoming more common due to concerns about morbidity and mortality after surgical pleurodesis as patients are usually older with more underlying medical diseases. Until last year, there have been no updates on the international recommendation of pneumothorax management since the British Thoracic Society (BTS) guideline published in 2010. The latest 2023 BTS guideline on pleural diseases provides us a good opportunity to review the latest development and literature of the care for patients with spontaneous pneumothorax. This article will explore the goals of pneumothorax treatment including air evacuation, cessation of persistent air leak and prevention of recurrence.
