The Z line in the esophagus is the term for a faint zig-zag impression at the gastro-esophageal junction that demarcates the transition between the stratified squamous epithelium in the esophagus and the intestinal epithelium of the gastric cardia (the squamocolumnar junction).
The Z line is a normal finding but is not seen in every study. An irregular or elevated Z line indicates potential distal esophageal metaplasia / Barrett esophagus, although the actual risk of this finding is debated.
The Z-line, or Z-line junction, is the area where the esophagus meets the stomach. It is important because it separates the lining of the esophagus from the lining of the stomach. Disorders affecting the Z-line can cause various symptoms and require different diagnostic and treatment approaches. This guide provides a detailed overview of Z-line esophagus disorders, including their types, causes, symptoms, diagnostic tests, treatments, medications, surgeries, prevention strategies, and when to see a doctor.
