Abstract: With the continuous development of robotic surgery technology, the application of indocyanine green (ICG) as a fluorescent dye in robotic gastrectomy has gradually attracted attention. ICG can accumulate in tumor tissues through local or intravenous injection, enabling real-time imaging of tumors and related lymph nodes, thereby enhancing the precision and safety of surgery. ICG can effectively aid in identifying tumor boundaries, reducing the risk of missed exci-sions, and improving postoperative prognosis in robotic gastrectomy. However, further optimization of imaging technology, large-scale clinical trials, and integration with new technologies such as artificial intelligence are still needed to enhance the reliability and efficacy of ICG application. In the future, the broad prospect of ICG in robotic assisted-gastrectomy is expected to promote the precision medicine process of gastric cancer treatment. The authors analyze the development and evolution of robotic surgical systems, the biological characteristics of ICG tracing, and the application of ICG tracing in the minimally invasive field of gastric cancer, aiming to explore the application status and development prospects of ICG in this field.
