Types

There are two major kinds of hiatus hernia:

• The most common (95%) is the sliding hiatus hernia, where the gastroesophageal junction moves above the diaphragm together with some of the stomach.
• The second kind is rolling (or paraesophageal) hiatus hernia, when a part of the stomach herniates through the esophageal hiatus beside, and without movement of, the gastroesophageal junction. It is about 100 times less common than the first kind.

A third kind is also sometimes described, and is a combination of the first and second kinds.
