Gastro-esophageal junction
Updates to Article Attributes
Body
was changed:
The gastro-oesophageal junction (GOJ) (also known as the oesophagogastric junction) is the part of the gastrointestinal tract where the oesophagus and stomach are joined.
Gross anatomy
The GOJ is normally mostly intra-abdominal and is is 3-4cm in length. To some extent, the oesophagus slides in and out of the abdomen during respiration and when there is elevation of intra-abdominal pressure.
Histology
It is comprised of two histologically distinct areas:
- stratified squamous epithelium (same as the oesophagus superiorly)
- columnar epithelium (same as the stomach inferiorly)
Where these two distinct areas join, there is an abrupt but non-linear change in the mucosal layer: this is called the Z-line.
