Figure 3: Robotic real-time vessel navigation using indocyanine green fluorescence for lymph node dissection along the left gastroepiploic vessels during the robotic distal gastrectomy. (a) Exposing the roots of LGEVs. Dotted line: LND along the LGEVs. (b) Real-time vessel imaging visualised the fluorescence of the SA, LGEVs and IPA. Dividing the LGEA while preserving the IPA. Dotted line: LND along the LGEVs. (c) Final view of LND along LGEVs preserving the IPA. (d) Final view of LND along LGEVs confirming the blood supply of the SGVs, IPA and spleen. LN: Lymph nodes, LND: Lymph node dissection, SA: Splenic artery, LGEVs: Left gastroepiploic vessels, IPA: Inferior polar artery, SGVs, Short gastric vessels
