Robotic gastrectomy (RG) for gastric cancer has gained popularity in recent years, facilitating more intricate surgical procedures. However, the technical complexity of infra-pyloric lymph node dissection in RG arises from the complex anatomy of the region. Embryologically, the pancreatic head is formed by the fusion of the ventral and dorsal pancreatic primordia during development, and recognizing the embryological fusion plane (EFP) may help prevent misleading results during infra-pyloric lymph node dissection. This report presents an operative technique that emphasizes the importance of recognizing the EFP.

The lymphatic system has two main functions: to return extracellular fluid back to the venous circulation and to expose antigenic substances to the immune system. As the collected fluid passes through lymphatic channels on its way back to the systemic circulation, it encounters multiple nodes consisting of highly concentrated clusters of...
