Prospective Randomized Controlled Trials on Clinical Outcomes of Indocyanine Green Tracer Using in 3D Plus Ultra High Resolution Laparoscopic Gastrectomy With Lymph Node Dissection for Locally Advanced Gastric Cancer
Patients with locally advanced gastric adenocarcinoma (CT2-4a N-/+ M0) were selected as study subjects to investigate the safety, efficacy, and feasibility of ICG near-infrared imaging tracing in 3D plus ultra high resolution laparoscopic gastrectomy with lymph node dissection for gastric cancer.
