3 lis 2022 · 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.

As commonly seen in clinical practice, biopsies are obtained from the normal Z-line or a Z-line with <1 cm of variability.
28 lut 2018 · An irregular Z line is characterized by < 1 cm columnar tongues that extend proximal to the gastroesophageal junction, a finding that has been reported in approximately 10–15% of the population undergoing upper endoscopy [ 1, 2 ]. In those with an irregular Z line, there is up to a 44% prevalence of intestinal metaplasia (IM) [ 3 ].
