Abstract: This article presents two cases of extrahepatic portal vein anomalies that can be challenging during lymph node (LN) dissection in gastric cancer surgery. The first case was a participant for a clinical trial assessing the completeness of D2 LN dissection. The trial utilized near-infrared (NIR) lymphangiography with indocyanine green only after completing dissection of a certain topological LN station to detect any residual lymphatic tissue. However, the patient was excluded from the trial due to an unexpected extrahepatic portal vein confluence anomaly and aberrant common hepatic artery. Consequently, continuous lymphatic navigation with NIR imaging was utilized for remaining surgery. The second case featured a patient with an anteriorly positioned splenic vein, hindering LN dissection along the left gastric artery. Preoperative identification of great vessel anomalies around the stomach is critical to prevent life-threatening complications during LN dissection in gastric cancer surgery. Augmented imaging technology can be a valuable tool in ensuring oncologic safety and precision.
