ICG-NIR Guided Lymph Node Dissection in Gastric Cancer


As the survival rate of patients with gastric cancer has increased, there has been a growing interest in interventions that improve postoperative quality of life. Therefore minimally invasive surgery or endoscopic resection has been performed much more frequently. However, adequate lymph node dissection is important as well. The aim of the study is to identify the feasibility of indocyanine green – near infra-red (ICG-NIR) guided sentinel lymph node dissection for the treatment of gastric cancer.
