The normal pleural cavity is under a sealed negative pressure. If air escapes into the pleural cavity, it is called a pneumothorax. The main reason for the occurrence of pneumothorax is the presence of alveoli on the surface of lung tissue, which is like a blown up balloon with very thin walls and can easily rupture. Once ruptured, gas will enter the chest cavity and pneumothorax will occur. The main symptoms of pneumothorax are chest pain and difficulty in breathing, and some patients will have pleural effusion, and serious cases can have hemorrhage, which is life-threatening and must be operated urgently. According to statistics, the possibility of recurrence of pneumothorax within 2 years is 30-50%, the chance of recurrence after the second attack is 50%, the third is 62%, and the fourth is 80%; while the chance of recurrence of pneumothorax after thoracoscopic treatment is less than 3%. What is the treatment for pneumothorax and pulmonary alveoli? The traditional methods of treating pneumothorax include thoracentesis and closed chest drainage, but both methods only promote the discharge of gas from the chest cavity and relieve the symptoms, but do not solve the cause of pneumothorax – pulmonary alveoli, and do not reduce the chance of pneumothorax recurrence. Thoracoscopic suturing or resection of large pulmonary alveoli is the preferred method for treating pneumothorax. Thoracoscopic treatment has the following advantages: 1. less trauma and less pain, with a total of 3 incisions, located in the axilla, each incision is only 2 cm, with small scars; 2. fast recovery after surgery, able to move on the ground on the 2nd day after surgery; 3. exact efficacy and little possibility of recurrence after surgery. What is the cost of thoracoscopic treatment of pneumothorax? Generally the whole hospitalization cost for thoracoscopic treatment of spontaneous pneumothorax is about 20,000 RMB, but because some of these patients have more alveoli, especially those connected into grape bunches, and the base is too wide to be sutured, they need to be cut and sutured with a special disposable instrument, ENDO-GIA (Endoscopic Cutting and Suturing Instrument), and the operation cost will increase accordingly.
