Many systematic reviews have been published to evaluate the clinical benefits of robotic surgery for gastric cancer. However, these reviews have investigated various outcomes and differ considerably in quality. In this overview, we summarize the findings and quality of these reviews. A comprehensive literature search was conducted using PubMed, Scopus, and the Cochrane Central Register of Controlled Trials to identify systematic reviews and meta-analyses that compared robotic surgery with laparoscopic surgery for gastric cancer. We summarized the results of the meta-analyses and evaluated the quality of the reviews using the AMSTAR-2 tool. The literature search identified 14 eligible reviews. The reviews showed that estimated blood loss was significantly less and time to resumption of oral intake was significantly shorter in patients who underwent robotic surgery than in those who underwent laparoscopic surgery. However, no significant differences in other outcomes were found between the two types of surgery. The quality of the included reviews was judged to be critically low. In conclusion, the available evidence, albeit of critically low quality, suggests that robotic surgery decreases estimated blood loss and shortens the time to resumption of oral intake in patients with gastric cancer. There is currently no high-quality evidence that robotic surgery has clinical benefits for gastric cancer patients.
