The diaphragm, the hiatus and the gastroesophageal junction

Abstract

The point where the esophagus connects to the stomach, known as the cardia, its transition and relationship with the diaphragmatic hiatus, its fibromembranous attachments, the existence of an anatomic gastroesophageal sphincter and its real morphology, and the interaction between all these elements, have been subject of debate for decades that still persist. The aim of this article is to describe the updated information of such structures.
