A paraesophageal hernia is also known as a hiatal hernia, where a portion of the stomach slides through the diaphragm and into the chest. This may cause symptoms of pain, heartburn, reflux, and difficulty swallowing food. Sometimes it causes food or even liquids to become stuck as they go down the esophagus.
Hiatal hernias occur when part of the stomach slides through the opening in the diaphragm where the esophagus passes from the chest into the abdomen. A sliding hiatal hernia is the most common type and occurs when the lower esophagus and portions of the stomach slide through the diaphragm into the chest.Paraesophageal hernias occur when only the stomach herniates into the chest alongside the esophagus. hernia is the protrusion of an organ or piece of tissue from its normally contained space. In the abdomen, a hernia usually involves a piece of bowel, or omentum, which is a fatty apron that hangs down from the midportion of the colon (large intestine), protruding through a weak area in the abdominal wall.
