Progress of Lymphatic Navigation Technique in Minimally Invasive Surgery for Gastric Cancer

The combination of standardized D2 lymph node dissection and lymph node sorting after surgery can improve the survival of patients with gastric cancer and increase the accuracy of staging. With the development of different lymphatic tracers, individualized lymphatic navigation has become a new technical breakthrough in minimally invasive surgery for gastric cancer. Lymph node tracing is an important method to improve the quality of intraoperative lymph node dissection and correct the postoperative pathological stage. This article reviews the application status and progress of lymphatic navigation technology.
