PUB023 Effectiveness of Three-Dimensional Video System in Single Port Thorascopic Major Pulmonary Resection: Propensity Score Matched Analysis

Abstract

The aim of this study was to evaluate the surgical outcomes of video assisted thoracoscopic surgery using three dimensional high definition video system compared to two-dimensional system during single port major lung resection by propensity score matched analysis. Between March 2012 and December 2015, 213 patients underwent single port thoracoscopic anatomic lung resection for lung malignancy by one surgeon. The patients who underwent wedge resection or converted to open thoracotomy were excluded from analysis. Patient group was divided into two group: two-dimensional (n=95) and three-dimensional group (n=118). Seventy-six patients of each group were matched using propensity score analysis. There were no significant differences in operation time (p=0.44), conversion to open thoracotomy (p=0.698) and postoperative complication (p=0.15) between two- and three-dimensional video system for major lung resection. Subgroup analysis showed that procedure times for lobectomy with segmentectomy (p<0.01), sleeve resection (p=0.64), and additional procedure (p=0.10) were likely to be shorter in three-dimensional group. The number of excised mediastinal lymph nodes was not significantly different (p=0.81). Eye discomfort or headache when using glasses for three-dimensional image was not observed in our study. Three-dimensional video system is a safe and feasible option for minimally invasive major lung resection for lung cancer and might be helpful in performing thoracoscopic complex procedures; segmentectomy, sleeve resection under single port thoracoscopic surgical field.
