Emphysema is a common chronic obstructive pulmonary disease, and its pathophysiological changes are, in layman’s terms, the blockage of many small airways in the lungs and the inflation and expansion of the lungs. This change can seriously affect the patient’s respiratory function, manifesting as difficulty in breathing and, in severe cases, even in dressing and undressing, and in eating, feeling “out of breath”. Traditionally, the treatment of emphysema is based on internal medicine, including oxygenation, prevention of lung infections, and bronchial decongestion, but its effectiveness is extremely limited. Statistically, the 5-year survival rate of patients with end-stage emphysema is less than 50%, similar to that of non-small cell lung cancer (a major type of lung cancer, as opposed to small cell lung cancer, which is more malignant) after surgery. One of the surgical treatment options for emphysema is lung transplantation, but this technique is not yet mature in China, and it is not yet ready for real implementation, and it is expensive (tens of thousands of dollars for surgery and lifelong use of expensive immunosuppressive drugs after surgery). in the late 1990s, a new procedure for emphysema, lung decompression, was carried out abroad, with good The results were good. Practice has confirmed that most patients’ symptoms, exercise capacity, and lung function indicators can be significantly improved, and in the words of the patient’s family, “it’s like a new person!” This effect lasts more than 3-4 years, in other words, the clock is turned back at least 4 years! What exactly is lung decompression? In short, it is a reduction in the size of the lung by cutting off a portion of the lung, which does not sound complicated, but because the patient has very poor respiratory function and is elderly, the operation is risky and the preoperative preparation is extremely difficult. Moreover, the surgical removal of a portion of the lung places high demands on the medical staff in terms of how to determine the site and the extent of the removal and how to make the patient pass through the operation smoothly.
