[Reasons for Conversion to Thoracotomy in 83 Cases during Video-assisted Thoracic Surgery Lobectomy: A Summary of 1,350 Consecutive Operations by A Single Surgical Team].
摘要
BACKGROUND: Video assisted thoracic surgery (VATS) is the main surgical method for lung cancer. The aim of this study was to analyze the reasons for conversion to thoracotomy in 83 cases among 1,350 consecutive cases who underwent video-assisted thoracic surgery (VATS) lobectomy by a single surgical team, in order to achieve a deeper understanding of the rules and the opportunity for conversion to thoracotomy in VATS lobectomy under normal conditions. METHODS: The clinical data of 1,350 patients who underwent VATS lobectomy between September 21, 2009 and June 1, 2020, by a single surgical team in the Fifth Department of Thoracic Surgery of the Fourth Hospital of Hebei Medical University were retrospectively analyzed. There were 773 males and 577 females, aged 8-87 years, with a median age of 61.3 years, including 83 cases of benign diseases, 38 cases of lung metastases, and 1,229 cases of primary lung cancer. The cases with stage I, II and IIIa were 676, 323 and 230, respectively. The cases of left upper, left lower, right upper, right middle, right lower, right middle and upper and right middle and lower lobectomy were 301 (22.30%), 231 (17.11%), 378 (28.00%), 119 (8.81%), 262 (19.41%), 16 (1.19%) and 43 (3.19%), respectively. RESULTS: In the cohort of 1,350 consecutive patients with VATS lobectomy, 83 patients (6.15%) were converted to thoracotomy for different reasons. The conversion rate of benign lesions was significantly higher than that of malignant tumors (P<0.05). The conversion rate in stage IIIa was significantly higher than that in stage I and II (P<0.05). The conversion rate of combined lobectomy was significantly higher than that of single lobectomy (P=0.001). The conversion rate of left upper lobectomy was significantly higher than that of other single lobectomy (P<0.001). The conversion rate of right middle lobectomy was significantly lower than that of other single lobectomy (P=0.049). The main reasons for conversion were vascular injury (38.55%), l
