Esophageal hiatus Esophageal hiatus. In human anatomy, the esophageal hiatus is an opening in the diaphragm through which the esophagus and the vagus nerve pass. It is located in the right crus, one of the two tendinous structures that connect the diaphragm to the spine. Fibers of the right crus cross one another below the hiatus.

Stomach acid, accidentally swallowed harsh chemicals, and other irritants may injure the esophageal lining, causing inflammation (esophagitis) and the formation of scar tissue.

Gastroesophageal reflux disease Gastroesophageal reflux disease. Gastroesophageal reflux disease (GERD) is a condition in which the stomach contents leak backwards from the stomach into the esophagus (the tube from the mouth to the stomach). This can irritate the esophagus and cause heartburn and other symptoms. When you eat, food passes from the throat to the stomach through the esophagus. A ring of muscle fibers in the lower esophagus prevents swallowed food from moving back up. These muscle fibers are called the lower esophageal sphincter (LES).

Esophageal varices In medicine (gastroenterology), esophageal varices (or oesophageal varices) are extremely dilated sub-mucosal veins in the lower third of the esophagus. They are most often a consequence of portal hypertension, commonly due to cirrhosis; patients with esophageal varices have a strong tendency to develop bleeding.n medicine (gastroenterology), esophageal varices (or oesophageal varices) are extremely dilated sub-mucosal veins in the lower third of the esophagus.
