Clinical Outcomes of Indocyanine Green Tracer Using in Laparoscopic Gastrectomy With Lymph Node Dissection for Remnant Gastric Cancer

Summary

Patients with resectable remnant gastric cancer were selected as study subjects to investigate the safety, efficacy, and feasibility of ICG near-infrared imaging tracing in guiding laparoscopic lymph node dissection for remnant gastric cancer by comparing injection ICG group and non-injection ICG group.
