Experience of Simultaneous Bilateral Open Surgery and VATS for Pulmonary Metastasectomy

Abstract

Background Resection is the current treatment of choice for resectable bilateral pulmonary metastases. This study aimed to compare the differences in outcomes between simultaneous bilateral open and video-assisted thoracic surgery (VATS) for pulmonary metastasectomy.

Methods Forty-three patients underwent pulmonary metastasectomy through one-stage bilateral open thoracotomy (n = 16) and VATS (n = 27) between 2011 and 2020. Perioperative and oncological data were analyzed.

Results The predominant primary tumor histology in both groups was colorectal cancer. The operative time, blood loss, and pain score on postoperative day 1 (POD1) were higher in the open group (p < 0.001, 0.009, and 0.03, respectively). No significant differences in pain score on POD2 and POD3, postoperative length of stay, or complications were found. Notably, numbers of the resected metastatic lung nodules were significantly greater in the open group (median number: 9.5 vs. 3, p < 0.001). Recurrence-free survival (RFS) and overall survival (OS) were comparable. The median RFS was 15 months (interquartile range [IQR], 6–22) in the open group and 18 months (IQR, 8–47) in the VATS group. The median OS was 28 months (IQR, 14–44) and 29 months (IQR, 15–54) in the open group and VATS group, respectively.

Conclusion One-stage bilateral pulmonary metastasectomy is safe and reduces medical expenditures in selected patients regardless of surgical approach. Although the open group harbored a greater number of metastatic foci, perioperative and oncological outcomes were similar to that of the VATS group.
