Application of laparoscopic surgery (LS) has expanded worldwide in the various fields due to the potential advantage of being less invasive than open surgery; however difficulty in recognizing positional relationship of the organs is one of the disadvantages of this kind of surgery. In order to compensate this drawback, preoperative three-dimensional computed tomography (3D-CT) simulation is regarded as promising. In gastric cancer surgery, 3D-CT simulation seems particularly effective in the splenic hilar dissection, because this region is associated with remarkable anatomical variation with complexity. As effects from the use of 3D-CT simulation, reduction of blood loss or complication rate, shortening of operation time and enhancement of surgical quality are expected. In this article, we introduce our methodological protocol of 3D-CT simulation in gastric cancer surgery with clinical case examples, and also additionally review previous publications reporting this imaging technology.
由于腹腔镜手术（LS）相较于开放手术具有侵入性较小的潜在优势，其在全球各个领域的应用都有所扩展；然而，识别器官位置关系的困难是这类手术的缺点之一。为了弥补这一缺陷，术前三维计算机断层扫描（3D-CT）模拟被认为很有前景。在胃癌手术中，3D-CT模拟在脾门淋巴结清扫术中似乎特别有效，因为该区域存在显著且复杂的解剖变异。预期使用3D-CT模拟会带来减少失血或并发症发生率、缩短手术时间以及提高手术质量等效果。在本文中，我们通过临床病例实例介绍了胃癌手术中3D-CT模拟的方法方案，并且还额外回顾了此前报道这项成像技术的文献。
