Objective: To study the current development of thoracic surgery in China. Methods: Chinese Society for Thoracic and Cardiovascular Surgery and Chinese Association for Thoracic Surgeons jointly conducted a network survey to directors of thoracic surgery departments in the tertiary hospitals in China from November to December 2018. The contents of the survey included the basic information of the hospital and the status of thoracic surgery department in the hospital. Rank sum test was used to compare the data between different regional hospitals Results: A total of 636 tertiary hospitals participated in the survey. The total number of beds for thoracic surgery departments was 30 646, with M(Q(R)) of 40(20) (range: 3 to 393) for each hospital. The total number of thoracic surgeons was 6 747, with M(Q(R)) of 9(6) (range: 1 to 75) in each hospital. In 2015, a total of 312 425 operations were performed in the 636 hospitals, with M(Q(R)) of 268(484.5) (range: 4 to 8 320) for each hospital. The total number of lung cancer surgeries was 146 601 in 2015, with M(Q(R)) of 100(216) (range: 0 to 6 911) operations in each hospital. The total number of esophageal cancer operations was 67 076, with M(Q(R)) of 40(95) (range: 0 to 1 550) in each hospital. Minimal invasive thoracic surgery was performed in 94.3% (601/636) of the hospitals, with 86.6% (551/636) of hospitals carried out video-assisted thoracoscopic (VATS) lobectomy. Among the hospitals performing VATS lobectomy, 89.3% (492/551) of them started to perform the technique after 2006, and 93.1% (513/551) of them do single-direction thoracoscopic lobectomy. A total of 403 640 VATS lobectomies had been performed until 2015, including 163 682 cases of single-direction thoracoscopic lobectomy. In 2015, 73.74% (108 116/146 601) lung cancer operations and 37.44% (25 110/67 076) of esophageal cancer resections were performed by minimally invasive technique. The development level of hospitals among eastern, middle and Western China was different significantly on number of doctors, number of total operations, number of lung cancer surgeries, proportion of minimally invasive lung cancer surgery, number of esophageal cancer surgeries, and proportion of minimally invasive esophageal cancer surgery (χ(2)∶7.65 to 60.8, all P<0.05). Conclusions: The discipline of thoracic surgery, especially the minimally invasive thoracic surgery in China is now experiencing a rapid development. The proportion of minimally invasive lung cancer surgery is higher than that of in the developed countries. However, unbalanced development among different regions is still a great challenge in China.
