Tracer-Guided Complementary Dissection of Residual Lymph Node After Laparoscopic Radical Gastrectomy for Gastric Cancer

Radical lymphadenectomy can improve tumor staging accuracy and long-term survival of patients with gastric cancer. The procedure is typically performed by eye and depends on a surgeon’s experience. Indocyanine green (ICG) near-infrared (NIR) fluorescent imaging has improved sentinel lymph node localization in other cancers and has been incorporated into laparoscopic device technology. This procedure video illustrates an ICG tracer-guided complementary dissection of residual lymph node-bearing soft tissue after laparoscopic radical gastrectomy and general lymph node dissection in a patient with gastric cancer.
