Will a barium swallow show a hiatal hernia?
Correspondingly, can a hiatal hernia be missed on barium swallow?
There is a clear relation between the gastro-esophageal reflux disease and sliding hiatal hernia. As barium swallow examinations are rarely performed nowadays and esophageal manometry is not widely available, the diagnosis of hiatal hernia usually solely relies on upper gastrointestinal endoscopy.
Then, what tests are done for hiatal hernia?
Several tests can be done to help diagnose a hiatal hernia. These include a barium swallow test, an endoscopy procedure, esophageal manometric studies, a pH test and gastric emptying studies.
Most hiatal hernias are found incidentally, and they are usually discovered on routine chest radiographs or computed tomography (CT) scans performed for unrelated symptoms. When symptomatic, patients may experience heartburn, dyspepsia, or epigastric pain.
