Hiatal hernia (often referred to as hiatus hernia) is the protrusion (or hernia) of the upper part of the stomach into the thorax through a tear or weakness in the diaphragm. Symptoms may begin as reflux and dysphagia, but over time the acid returning moving up the esophagus may create a life threatening situation if not treated.
The following are possible causes or contributing factors for having an hiatal hernia:
Hiatal hernias affect anywhere from 1 to 20% of the population. Ninety five percent of these reported cases are "sliding" hiatal hernias, in which the LES protrudes above the diaphragm along with the stomach, and only 5% are the "rolling" type, in which the LES remains stationary but the stomach protrudes above the diaphragm.
Besides discomfort from reflux and dysphagia, hiatal hernias can have severe consequences for patients if not treated. While sliding hernias are primarily associated with gastro-esophageal acid reflux (GERD), rolling hernias can strangulate a portion of the stomach above the diaphragm. This strangulation can result in esophageal or GI tract obstruction and even become ischemic and necrotic.
