Background: 3D laparoscopic (3D-LAG) and robot-assisted gastrectomy (RAG) are both new minimally invasive surgical therapies for gastric cancer. In this study, we aimed to compare the short-term surgical outcomes between 3D-LAG and RAG.
Methods: Between June 2015 and June 2017, 164 patients who underwent 3D-LAG (n=99) or RAG (n=65) for gastric cancer were enrolled. The clinicopathological factors and short-term surgical outcomes were compared with retrospectively analysis.
Results: The clinicopathological factors between the two groups were well matched. Postoperative recovery factors including the days of first flatus, days of eating liquid diet and hospital stay were similar. The rate of postoperative complications between the two groups were with no statistical differences (3D-LAG: 4.5% versus RAG: 5.3%, P=0.583). The rate of positive margins, rate of R0 resection and number of harvested lymph nodes were all similar (P=0.218, P=0.698 and P=0.556). However, 3D-LAG was associated with less blood loss (P=0.014) and shorter operative time (P<0.001). In the subgroups of patients with total gastrectomy, 3D-LAG had less blood loss and shorter operative time than RAG (P=0.006 and P<0.001), while for distal gastrectomy, blood loss and operative time showed no statistical differences.
Conclusions: This study suggests that 3D-LAG is a novel and acceptable surgical technology in terms of surgical and oncological outcomes. 3D-LAG is a promising approach for gastric cancer therapy, with less blood loss, shorter operative time and satisfied postoperative complication rate.
