[Update on primary spontaneous pneumothorax - conservative or primarily surgical therapy?]

Spontaneous pneumothorax is a potentially life-threatening situation. Therefore, it is mandatory to treat it safely. The incidence is approximately 10 out of 100 000 residents per year. It occurs through an immediate disruption of the visceral pleura that results in an accumulation of air in the pleural space. According to its etiology, spontaneous pneumothorax is divided into 2 groups. Whereas primary spontaneous pneumothorax occurs in healthy individuals without any detectable lung disease, secondary spontaneous pneumothorax occurs in patients with preexisting. Diagnosis of pneumothorax is typically made by chest x-ray. After diagnosis pneumothorax is traditionally treated by an insertion of a thoracic tube.Recently, thoracic ultrasound gained influence in diagnosis of pneumothorax and primarily conservative treatment strategies have been shown to be safe and equally effective in particular groups of patients. This article aims to present and discuss these upcoming strategies.
