Hiatal hernias and paraesophageal hernias are common clinical entities and have a well-known classification system. Multiple modalities have been used to illustrate these hernias, most relying on artists' renderings or two-dimensional radiographic studies. However, surgeons would benefit from a comprehensive graphic representation of hiatal hernias based on current imaging technologies. We have applied polygonal mesh surface modeling techniques to render dynamic three-dimensional computed tomography-based models of the four recognized types of hiatal hernias. The resulting images allow nearly real-time navigation in an intuitive and clinically relevant fashion. This model should clarify and eventually advance the existing classification by applying modern and sophisticated image processing to established concepts.
食管裂孔疝和食管旁疝是常见的临床病症，并有一个广为人知的分类系统。已经使用了多种方式来说明这些疝，大多数依赖于艺术家的渲染图或二维放射学研究。然而，基于当前成像技术的食管裂孔疝综合图形表示将使外科医生受益。我们应用了多边形网格表面建模技术来呈现基于动态三维计算机断层扫描的四种公认类型食管裂孔疝的模型。生成的图像允许以直观且与临床相关的方式进行近实时导航。该模型应通过将现代且复杂的图像处理应用于既定概念来澄清并最终推进现有的分类。
