28 lut 2018 · The Z line demarcates the squamocolumnar junction (SCJ), the transition from the squamous esophageal mucosa to the columnar mucosa lining the stomach, or in cases of Barrett’s esophagus, between the squamous and intestinalized columnar epithelium of the metaplastic segment.
8 sie 2022 · Given these risk factors, screening EGD is recommended. While appropriate screening was performed, biopsies were obtained from an irregular-appearing Z line. The current definition of BE requires columnar mucosa of at least 1 cm in length in conjunction with intestinal metaplasia on biopsies.
8 sie 2023 · The squamocolumnar junction, also referred as Z-line, is the area where the squamous epithelial lining of the esophagus (pale pink colored) meets the columnar lining mucosa of the stomach (salmon-colored).
Conclusions: The yield of biopsy at an “irregular z-line” is low. In addition, the risk of cancer in patients with this endoscopic finding and specialized intestinal metaplasia (even with dysplasia) is unknown.
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).
In order to determine which endoscopic alterations that can be attributed to a previous history of gastroesophageal reflux, three different endoscopic definitions of columnar-lined esophagus (CLE) were used: (1) ZAP I, An irregular Z-line with a suspicion of tongue-like protrusions; (2) ZAP II/III, Distinct, obvious tongues of metaplastic ...
29 paź 2020 · The term histologic squamo-columnar junction (SCJ) or Z-line refers to the transition between esophageal stratified squamous epithelium and columnar epithelium. It can be identified both by endoscopists (due to the white color of the squamous epithelium compared to the pinkish color of columnar epithelium) and by pathologists who easily ...
