Overview
Hiatal hernia occurs when a part of the stomach protrudes into the thoracic cavity through the esophageal hiatus of the diaphragm. Approximately 99% of hiatal hernias are sliding, and the rest 1% are paraesophageal hernia.Barium swallow may be helpful in the diagnosis of haitus hernia. Findings on an Barium swallow suggestive haitus hernia include anatomy and size of the hernia,orientation of the stomach location of the Gastroesophageal junction.
Barium swallow
- .Barium swallow may be helpful in the diagnosis of hiatal hernia. Findings on an barium swallow suggestive of haitus hernia include:[1]
- Anatomy of the hernia
- Size of the hernia
- Orientation of the stomach
- location of the gastroesophageal junction
- If a sliding hernia is suspected a greater than 2-cm division between the mucosal B ring at the site of the squamocolumnar junction and the diaphragmatic hiatus is noticed.
- If B ring not identified on barium swallow, evident of atleast 3 rugal folds is diagnostic of a sliding hiatus hernia.
- On barium swallow herniating of gastric fundus along the distal esophagus is diagnostic of a paraesophageal hernia.
