Recently, the technological advancements have led to the introduction of new three-dimension (3D) laparoscopic system. 3D technique in laparoscopic radical gastrectomy provides an abdominal strong stereoscopic depth and accurate operative field, and can be helpful for the beginner to shorten the learning curve. Moreover, spatial orientation becomes more accurate with 3D technique. 3D technique also has the advantages of clearer anatomical level, better vessel exposure, lymph node dissection and digestive tract reconstruction. However, there are still some defects of 3D laparoscopic system. For example, the surgeon may not adapt to 3D vision at the beginning, and special equipment is required to display the data.
