Classification of hiatal hernias using dynamic three-dimensional reconstruction.
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.
