Esophagitis is the inflammation of the esophagus caused by physical or chemical trauma. Reflux esophagitis is the reflux of gastric contents into the esophagus caused by an incompetent lower esophageal sphincter or a sliding hiatal hernia. Achalasia (cardiospasm) is the dilatation of the lower esophagus caused by a decrease in motility in the lower two thirds of the esophagus and ineffective peristalisis. This results in a sphincter that does not relax in response to swallowing causing an obstruction as food and fluid accumulate in the lower esophagus.
