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.
A hiatal hernia is a protrusion of the abdominal contents into the thorax through an enlarged oesophageal hiatus caused by a weakness or opening in the diaphragm. The four types of hiatal hernias are sliding, paraesophageal, mixed and giant hiatal hernia. Signs and symptoms: heartburn, gastro-oesophageal reflux, flatulence, belching, abdominal epigastric pain, nausea, non bilious vomiting, haematemesis, chest pain, shortness of breath and bowel sounds present in chest.
