Thoracoscopy is not unfamiliar to all of us, it can not only complete the operation that traditional open thoracotomy can accomplish, but also has the advantages of small incision, small injury and fast recovery that traditional open thoracotomy can not match. However, for huge tumors in the lung, thoracoscopy seems to be a little bit “incapable”, so it is necessary to “ask for help” from traditional open thoracotomy. (Surgical textbooks have clearly pointed out that the contraindications for thoracoscopic surgery include huge tumors and T2 lung cancer with a diameter larger than 5 cm.) But with the increasing development of thoracoscopic technology, will this status quo change? A 73-year-old patient, Mr. Xu, who had been coughing, coughing up yellowish-white sputum with blood in the sputum for 4 years, visited the Department of Thoracic Surgery II of the First Affiliated Hospital of China Medical University after a huge mass in the upper lobe of his right lung was detected by lung CT examination when he visited the local hospital for palpitations 1 month ago. His chest radiographs (Figure 1) and lung CT films (Figures 2, 3, and 4) suggested a large mass measuring approximately 14 × 9.5 cm. Because of Mr. Xu’s advanced age and frailty, he and his family were particularly interested in minimally invasive surgery. So is it possible to remove such a large lung tumor minimally invasively under thoracoscopy? After thorough preparation and delicate operation, this huge mass was completely resected under thoracoscopy on a certain day in December 2015, under the close cooperation of Dr. Liu Hongxu, the chief surgeon, and his assistants. (Figures 5 and 6 show the resected mass.) However, there was an extremely “embarrassing” situation during the operation. Although the removal of the mass was performed completely under thoracoscopy, the incision had to be enlarged in the end in order to remove the mass. Nevertheless, the final length of the incision was 13 cm (Figure 7), which was much smaller than that of a traditional open thoracotomy (usually about 30 cm), and none of the ribs were damaged. Nine groups of lymph nodes, totaling 36, were cleared intraoperatively. The patient recovered well after surgery and was able to move around on the 2nd day. (Refer to postoperative pathology Figure 8 and chest radiograph Figure 9). This case fully demonstrates that huge tumors can be resected thoracoscopically. However, it is worth thinking that the huge tumor in this case is of peripheral type, which is not very closely connected with the airways of the hilum and the large blood vessels, and can be resected by thoracoscopy. So, the question arises whether thoracoscopy is suitable for the resection of huge tumors in the hilum? It is believed that this question will also be solved in the near future.
