Abstract
With the rapid development and popularization of laparoscopic and robotic radical gastrectomy, gastric cancer surgery has gradually entered a new era of precise minimally invasive surgery. The era of precision medicine has put forth new requirements for minimally invasive surgical treatment of patients with gastric cancer at different disease stages. For patients with early gastric cancer, avoiding surgical trauma caused by excessive lymph node dissection improves quality of life while pursuing radical treatment of the tumor. In patients with advanced gastric cancer, systematic lymph node dissection can be achieved without increasing surgical complications. With the successful application of indocyanine green (ICG) fluorescence imaging technology in minimally invasive surgical instrumentation in recent years, researchers have found that ICG fluorescence imaging yields good tissue penetration and can identify lymph nodes in fat tissue better than other dyes. Therefore, whether ICG fluorescence imaging technology can guide surgeons in performing safe and effective lymph node dissection has attracted much attention. The present review discusses the clinical applications and research progress of ICG tracer-guided lymph node dissection in patients with gastric cancer.
