"HIS angle" refers to a normal acute angle formed between the abdominal esophagus and the fundus of the stomach (large bulge or fundus) at the gastroesophageal junction (esophagogastric junction). This angle is one of the important factors in preventing gastroesophageal reflux disease. When the fundus is enlarged by air or other gastric contents, the thoracic esophageal structures are "pushed" from left to right, closing the gastroesophageal flap valve.

Diaphragmatic hernia is a defect or opening in the diaphragm that allows abdominal organs to move into the chest cavity. A hiatal hernia occurs when the stomach or other organs protrude into the mediastinum through the esophageal opening of the diaphragm.
