The patient, Zhang, suffered from severe chest tightness, shortness of breath, distension and pain, and could not lie down, and could only sleep sitting up at night, which was very painful. Although the symptoms were relieved for a while, the pleural cavity was soon filled with fluid again and the symptoms of chest tightness and breath-holding reappeared, even getting worse. Malignant pleural fluid thus tormented the old Zhang sleep and food, pain. With the idea of giving it a try, his family sent him to the thoracic surgery department. According to his condition, the doctor suggested him to do pleural adhesion fixation to completely eliminate the stubborn malignant pleural fluid. After careful preparation, Lao Zhang underwent a 2-hour chest surgery under general anesthesia without any pain. After the operation, he was surprised to find that the symptoms of chest tightness and breathlessness disappeared, and he was able to rest quietly at night, his appetite increased significantly, and his spirit became pleasant, and what made him happier was that there were only two small 1cm-long wounds on the chest site. Zhang not only wondered: what kind of surgery has such a miraculous effect? It turns out that the old man underwent the popular minimally invasive thoracoscopic surgery, which is commonly known as chest “keyhole” surgery. The doctor used general anesthesia to perform the surgery, so that the patient could have no pain during the operation. First, a 1 cm incision is made in the side of the chest wall, through which a tubular thoracoscope is inserted and connected to a camera system to observe the situation inside the chest cavity on a TV screen, including the location of the tumor, the presence of metastases in the pleura and the nature of the pleural fluid. Then, a small 1 cm long incision is made in front of the patient’s chest wall, through which special instruments are inserted, and the surgeon can watch the operation on the TV screen. For more complex procedures, a third 1 cm incision can be made behind the chest wall to assist with the intrathoracic operation. The surgeons first release the adhesions in the chest cavity, aspirate the residual fluid, and peel off the fibrous membrane that has formed on the surface of the lung, which interferes with the expansion of the lung. The patient is usually able to get out of bed and move around on his own on the first day after surgery. Talc is one of the most effective drugs to promote adhesions in the chest cavity, which can cause extensive dense adhesions in the chest cavity, so that no more pleural fluid can grow in the chest cavity. After his pleural fluid was controlled, his body gradually became stronger and his confidence in overcoming the disease was strengthened, and he received another cycle of chemotherapy on the advice of his doctor, and his lung cancer was initially controlled and his quality of life was further improved.
