The esophageal hiatus gives passage to the oesophagus as well as the anterior and the posterior vagal trunk, esophageal branches of the left gastric artery and vein, and some lymphatic vessels.

Mar 8, 2024 · The esophageal hiatus is an oval shaped aperture located in the right crus of the diaphragm, at the level of the tenth thoracic vertebra. It transmits the esophagus, as well as the anterior and posterior vagal trunks, esophageal branches of the left gastric vessels and some lymphatic vessels.

Feb 13, 2025 · It then enters the abdomen via the oesophageal hiatus (an opening in the right crus of the diaphragm) at T10. The abdominal portion of the oesophagus is approximately 1.25cm long – it terminates by joining the cardiac orifice of the stomach at level of T11.

The esophageal hiatus is formed by the right crus of the diaphragm in the majority of subjects. Contraction of the hiatus exerts a sphincter-like action on the lower esophageal sphincter (LES). The aim is to study the hiatal anatomy (using CT scan ...

The esophageal hiatus is situated in the muscular part of the diaphragm at the level of the tenth thoracic vertebra, and is elliptical in shape. It is placed above, in front, and a little to the left of the aortic hiatus, and transmits the esophagus, the vagus nerves, and …

The oesophageal hiatus is a long and oblique opening in the diaphragm where the thoracic section of the oesophagus passes into the abdomen. Enlarged hiatal surface and insufficiency are considered to be associated with gastroesophageal reflux disease (GERD) and hiatal hernia (HH).

Feb 6, 2025 · Abdominal: it passes through the esophageal hiatus of the diaphragm, 40 cm from incisors teeth. Layers of esophageal tube: (from outside to inside) Tunica adventitia: loose connective tissue, that separates the esophagus from the surrounding structure in the mediastinum (esophagus has no serosa).

Nov 23, 2022 · The esophageal hiatus is the opening in the diaphragm through which the esophagus passes from the thoracic to the abdominal cavity. It is one of three apertures in the diaphragm and is located in the right crus.

It seems important to define the normal size, as crural closure is an important part of surgical treatment of gastroesophageal reflux disease (GERD) and hiatal or paraesophageal hernias. The aim of this study was to determine normal values for the size of the esophageal hiatus.
