Overview
A 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 a hiatus hernia. Findings on a Barium swallow suggestive hiatus hernia include anatomy and size of a hernia, the orientation of the stomach location of the Gastroesophageal junction.
Barium swallow
- .Barium swallow may be helpful in the diagnosis of a hiatal hernia. Findings on an barium swallow suggestive of hiatus hernia include:[1] [2] [3]
- Anatomy of a hernia
- Size of a hernia
- Orientation of the stomach
- location of the gastroesophageal junction
- If a sliding hernia is suspected a greater than a 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 at least 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.
