Outline of Final Research Achievements

This study aims to establish the navigation system of sentinel node in gastric cancer. In an open MRI operating theater, the laparoscopic monitor clearly showed the augmented reality models of the sentinel node which is enhanced by superparamagnetic iron oxide (SPIO) injected into the gastric mucosa endoscopically. After the appropriate condition setting, laparoscopic sentinel node dissection was technically able to be performed in this navigation system. Further clinical trials may elucidate the feasibility of this navigation system.
