Abstract:

Hiatal hernia is a common benign disease of digestive system, with an incidence of 4.5%-15.0% in the population. Surgery is the main treatment method for hiatal hernia. Due to the special anatomical structure around the esophageal hiatus, the operation is difficult and requires high anatomical knowledge. Three-dimensional visualization technology, with its high value of spatial sense, makes up for the deficiency of traditional CT/MRI image data to a certain extent, and can visually separate the contents of diaphragm, esophageal hiatus defect and hernia in a more intuitive, stereoscopic and all-round way, providing decision-making basis for making surgical plans before surgery. Our center obtained imaging information through preoperative thin slice CT scan of the chest and abdomen, conducted 3D reconstruction and data analysis, and finally presented 3D effects of digital models, so as to train surgeons on anatomical theoretical knowledge. This paper aims to explain the application of 3D visualization technology in the surgical teaching of hiatal hernia from the following aspects.
