The concept of fluorescence-guided navigation surgery based on indocyanine green (ICG) testifies to a developing interest in many fields of surgical oncology. The technique seems to be promising, also during nodal dissection in gastric and colorectal surgery in the so-called “ICG-guided nodal navigation”. In this video, we present the clinical case of 36-year-old man with a seeming early stage antral gastric adenocarcinoma, as preoperatively defined, submitted to a laparoscopic subtotal gastrectomy and D2+ lymphadenectomy. Before surgery, the patient was submitted to endoscopy with the objective to inject indocyanine green near the tumor (2mL injected into the mucosa 2cm proximally and 2cm distally to the tumor) in order to visualize the lymphatic basin of that tumor during the operation. Thanks to the ICG’s fluorescence with the light emitted from the photodynamic eye of our laparoscopic system (Stryker 1588® camera), it is possible to clearly visualize both the individual lymph nodes and the lymphatic collectors which drain ICG (and lymph) of the specific mucosal area previously marked with indocyanine green. This technique could allow for a more precise and radical nodal dissection and a safer work respecting vascular and nerve structures.
