Fig. 3. Hiatal anatomy and hiatal dimension. (A) Anatomy of esophageal diaphragmatic hiatus in normal subjects and patients with various types of hiatal hernia (HH). The hiatus is larger in dimension in 3 types of HH compared to normal subjects. (B–D) Hiatal dimensions (angle, large diameter [Larged] and small diameter [Smalld], and surface area) in normal subjects, patients with type 1, type 2, and type 3 HH. (B) Angle of the hiatus in relationship to spine, (C) long and short dimensions of hiatus, and (D) cross sectional area of the hiatus. Normal subjects have significantly smaller surface area, large and small diameters compared to 3 types of hernia but there is no difference among 3 type of HH. Data showed in median and interquartile range. LCFH, left crus forming right hiatal margin. +Outlier value in the group.
