High-resolution 3D CT Aids in Hiatal Hernia Diagnosis and Surgical Planning

The study demonstrates that high-resolution 3D computed tomography (CT) is a valuable tool for assessing the anatomical characteristics of hiatal hernias (HH) and aiding in surgical planning for laparoscopic or robotic antireflux procedures. CT scans accurately identified HH in 70% of patients and correlated well with endoscopic findings. Furthermore, the distance between the esophagogastric junction and the hiatus was found to significantly correlate with the area of the esophageal hiatus. However, no correlation was observed between CT and manometric findings or the Demester score.
