Image-guided Minimally Invasive Robotic Surgery Using Preoperative CT Scan for Gastric Cancer Patients

A Feasibility Study on Image-guided Minimally Invasive Robotic Surgery Using Preoperative CT Scan for Gastric Cancer Patients

The purpose of this study is to assess the feasibility of image-guided surgery in patients with early stage gastric cancer using Robotic Surgery with Tile-pro program. For the assessment of the feasibility, conversion to open or laparoscopic surgery due to disturbance of will indicate the failure.
