Abstract
Data of consecutive 1553 patients who underwent video assisted thoracoscopic surgical (VATS) pulmonary resection for lung cancer in the Department of Thoracic Surgery of Cancer Hospital of CAMS and PUMC between November 2014 and January 2016 were prospectively collected and analyzed. There were 716 males and 837 females. The mean age was 58.90 years (25 to 82 years) and the conversion rate was 2.7% (42/1553) in this cohort. After propensity score matching, there were 207 patients in single-port and two-port group, and 680 patients in three-port group. Propensity-matched analysis demonstrated that there were no significant differences in duration of operation (129 versus 131 minutes, P=0.689), intra-operative blood loss (63 versus 70 mL, P=0.175), number of dissected lymph nodes (12 versus 13, P=0.074), total hospital expense ($9928 versus $9956, P=0.884) and cost of operation ($536 versus $535, P=0.879) between VATS single-port, two-port and conventional three-port pulmonary resection groups. There was no significant difference in the complication rate between two groups (5.3% versus 4.7%, P=0.220). However, compared with three-port group, patients who underwent single port and two-port experienced shorter postoperative length of stay (6.24 versus 5.61 d, P=0.033), shorter duration of chest tube (4,92 versus 4,25 d, P=0.008), and decreased volume of drainage (926 versus 791 d, P=0.003). We concluded that the short term outcomes between VATS single-port, two-port and conventional three-port groups for the surgical treatment of lung cancer were comparable. However, compared with three-port VATS pulmonary resection, single-port and two-port were associated with shorter postoperative length of stay, shorter duration of chest tube, and decreased volume of drainage.
