Clinical Value of Four-hole Unilateral Dissecting Lobectomy and Mediastinal Lymph Node Dissection in the Treatment of Early Non-small Cell Lung Cancer

Background and objective Thoracoscopic lobectomy combined with mediastinal lymph node dissection has been considered as one of the standard surgical procedures for early lung cancer. After 20 years of development, thoracoscopic lobectomy has reached a consensus on reliability and minimally invasive. At present, thoracoscopic lobectomy has a variety of incisions, which gradually evolve into four holes based on three holes, and two or one hole as the operative approach. The aim of this study was to evaluate the clinical value of four-hole unilateral dissecting lobectomy and mediastinal lymph node dissection in the treatment of non-small cell lung cancer (NSCLC). The aim of this study was to investigate the clinical value of anatomical lobectomy with mediastinal lymphadenectomy under four-hole completely video-assisted thoracoscopic surgery (C-VATS) in the treatment of non-small cell lung cancer. Methods The patients undergoing lobectomy with mediastinal lymphadenectomy for NSCLC were identified in the Department of Thoracic Surgery, Yangzhou First People's Hospital, Yangzhou University from March 2015 to July 2016. Preoperative clinical diagnosis of peripheral-type early NSCLC. The patients were randomly divided into four-hole monophasic group (experimental group) and three-hole group (control group) according to the number of hospitalization before surgery. According to inclusion and exclusion criteria, the 39 cases assign in experimental group and 34 cases in the control group, including 36 males and 37 females; aged 38 to 84 years. The mean operation time, average blood loss, lymph node dissection group, average drainage, average extubation time and postoperative complications were compared between the two groups for statistical analysis. Results The two groups of patients were successfully completed surgery, no death after surgery. Mean bleeding in the two groups, the number of lymph node dissection group, the average postoperative drainage, the average time of extubation, postoperative complications, with no significant difference. The average operation time of the four-hole unidirectional group was shorter than that of the three-hole group. The difference was statistically significant (P
