In recent years, the incidence of gastric cancer has been decreasing year by year in the world, but the incidence of adenocarcinoma of the esophagogastric junction (AEG) has shown a significant upward trend, especially in Western countries such as Europe and the United States. The prognosis of AEG is poor, therefore, it is extremely necessary to establish AEG's best diagnosis and treatment strategies to improve the long-term outcome of AEG. Robotic surgery has been developed with the aim of improving surgical quality and overcoming the limitations of conventional laparoscopy in the performance of complex mini-invasive procedures. The study is designed to explore the clinical outcomes of the robotic assisted radical gastrectomy for advanced Siewert II/III esophagogastric junction adenocarcinoma (cT2-4a, N-/+, M0) by comparing with laparoscopic assisted.
