Long-term oncological outcomes in robotic gastrectomy versus laparoscopic gastrectomy for gastric cancer: a meta-analysis.

RG could provide comparable long-term oncological outcomes as well as LG for the treatment of gastric cancer. OS, DFS, and the recurrence rate by the long-time follow-up of RG were comparable with LG. Generally speaking, more randomized clinical trials and a larger patient cohort with longer follow-up are still essential to further demonstrate the value of the robotic surgery for gastric cancer.
