A sliding hiatus hernia or type 1 hiatus hernia is considered the most common type of hiatus hernia. They can be present to varying degrees and can also co-exist with other types (inclusive of a rolling hiatus hernia).
Many patients may have gastro-esophageal reflux. Some studies suggest most patients (up to 80%) with a clinically significant reflux have a sliding hiatal hernia.
Dysphagia can also be a frequently reported symptom 5.
This type results from a widening of the muscular hiatal tunnel and a circumferential laxity of the phreno-esophageal membrane, allowing a portion of the gastric cardia to herniate upward.
- small sliding hiatus hernias on CT colonography: some publications suggest that "small" sliding hiatal hernias can be commonly induced by colonic distention on CT colonography and should probably not be reported to avoid inappropriate diagnosis, workup, or treatment 1.
