How to evaluate the imaging

  • Hiatal Hernia diagnosis is based on anatomy:

    • Need to identify the GEJ, the stomach, and their relationship to the diaphragmatic hiatus

    • Use clues such as the contour of esophagus which should be “featureless” vs. rugae in stomach

    • Type I: 2 cm ruleat least 2 cm between EGJ and diaphragmatic hiatus to differentiate from “physiologic herniation”

    • Type IIIV: Gastric Volvuluslook for the NG tube, distention, obstruction of flow, and inversion of curvatures or other signs of rotation
