摘要

Background

In gastric cancer, resection of the primary tumor combined with adequate lymphadenectomy remains central to multimodal therapy with curative intent. While the extent of surgical radicality, most notably D2 lymphadenectomy, has been questioned in only selected trials, the operative approach has evolved substantially. Following the establishment of laparoscopic gastrectomy alongside the open technique, robot-assisted surgery has emerged as a promising option for complex oncological procedures. Although robotic and laparoscopic gastrectomy share minimally invasive access, the intraabdominal operative environment and thus oncological radicality and postoperative morbidity can differ due to the unique capabilities of robotic systems. International studies comparing robotic, laparoscopic, and open approaches report encouraging outcomes, with some suggesting advantages that support broader adoption of robotic techniques. East Asian countries, particularly Japan and Korea, have led the development of oncological gastrectomy by pioneering techniques and providing extensive clinical evidence. However, their standards of care differ markedly from those in Europe, as influenced by a higher incidence of gastric cancer, national screening programs, and the presence of very high-volume centers.

Conclusion

Therefore, maintaining a European perspective is essential. Differences in patient characteristics, healthcare structures, and case volumes necessitate region-specific evaluation of robotic gastrectomy. This article focuses on robot-assisted techniques in oncological gastrectomy and aims to contextualize current evidence and developments within the European setting.
