Sliding hiatus hernia
The sliding or axial hiatus hernia is characterized by displacement of the gastro-oesophageal junction and some portion of the stomach (usually the gastric cardia) above the diaphragm.
- the result is a symmetrical, bell-like dilatation of part of the stomach within the thoracic cavity
- there is a widening of the oesophageal hiatus and weakening of the phrenoesophageal ligament
- orientation of the stomach axis remains unchanged (1,2)
A sliding hiatus hernia is of no significance unless accompanied by abnormal gastro-oesophageal reflux (GORD).
- symptoms of GORD worsens with increasing size of the sliding hiatal hernia (1).
