How is a hiatal hernia diagnosed?
A barium swallow study, which is a specific X-ray procedure, can enable the proper evaluation of the esophagus to correctly diagnose a hiatal hernia. Other ways to diagnose a hiatal hernia are by CT scan or esophagoscopy (EGD). The esophagoscopy is a procedure where an endoscope, a long-thin flexible medical video camera, is inserted through the mouth into the esophagus and stomach and allows the examination of the upper digestive system.
