In clinical work, we often encounter patients with spontaneous pneumothorax referred from primary care hospitals. During the process of history taking, we feel that primary care physicians do not have a comprehensive grasp of the indications for spontaneous pneumothorax surgery, resulting in treatment not being very standardized. The main ones are as follows: 1. Pneumothorax occurs, and the examination reveals a clear combination of pulmonary hernias. 2.The first attack is tension pneumothorax (obvious lung compression, obvious mediastinal displacement, and obvious vital signs change). 3.At least one side of bilateral pneumothorax is done. 4.Pneumothorax that still leaks after more than 3 days of closed drainage. 5.Spontaneous hemopneumothorax. 6.Special professions: such as soldiers, athletes, frequent travelers, pilots, divers, etc. 7.Recurrent pneumothorax (i.e. the second occurrence on the same side). 8.The first pneumothorax after total pneumonectomy (healthy side). 9.First time pneumothorax, but the orthopantomogram shows that there are adhesions in the apex of the chest (personal experience). Nowadays, thoracoscopic surgery is the main surgical method.
