Efficacy of RUS GA Surgical Navigation for Robot-assisted Distal Gastrectomy in Gastric Cancer Patients

he RUS GA (Endoscopic Imaging Treatment Planning Software, E04010.01(2)) is an endoscopic imaging treatment planning software program. It creates a patient-specific simulation of the actual intra-abdominal surgical environment, allowing for the visualization of vascular structures and intra-abdominal organs during the surgical planning process and the operation. RUS GA utilizes preoperative CT images of the patient to segment organs and blood vessels and reconstructs them into a 3D model. Although there is no direct intervention with the patient, the surgeon uses RUS GA as a surgical navigation tool to simulate the surgery before performing the actual procedure.

Only standard treatment is performed.(Robot-assisted gastrectomy will be performed using without software RUS GA.)
