what is a hiatal hernia

Hiatal hernias, also known as paraesophageal hernias, occur when part of the stomach pushes into the chest through an opening in the muscle wall (known as the diaphragm) that separates the organs in the chest and abdomen.

At the University of Chicago Medicine, our surgeons are experts in repairing these types of hernias. In fact, our UChicago surgeons have developed a new type of surgery for large paraesophageal hernias that doesn’t require the placement of a permanent mesh implant.

What is a hiatal hernia or paraesophageal hernia?

A paraesophageal or hiatal hernia occurs when part of the stomach moves up into the chest through a hole in the muscular wall called the diaphragm.

The most common type is called a sliding hiatal hernia, in which the stomach and part of the esophagus “slide” up into the chest. A less common but more serious type is a paraesophageal hernia, which occurs when a large part of the stomach bulges up through the diaphragm into the chest so it is pushing into your lungs and heart.
