[Surgical anatomy of the esophagogastric junction]

Macroanatomic structures in the lower esophagus and at the GE-junction are shown and definitions are given. Muscle structures and thickening in the GE-junction region and fundus are shown and their relationship to the intraluminal high pressure zone is discussed. Anchorage of the esophagus to the diaphragm through the phreno-esophageal membrane in relation to aging, disposition and hiatal hernia is discussed. Vascularization of the esophageal wall by numerous submucosal arteries is shown.
