Is chest tube drainage losing ground in management of patients with spontaneous pneumothorax?

Primary spontaneous pneumothorax (PSP) refers to a pneumothorax occurring with no precipitating factor in an otherwise normal lung parenchyma. It is usually a disease of the young age with it being more common in tall thin males. Secondary spontaneous pneumothorax (SSP) refers to a pneumothorax associated with an underlying lung disease and is usually a disease of the more elderly population with a significantly higher morbidity and mortality in comparison to primary pneumothorax.
