3 lis 2022 · The Z line in the oesophagus is the term for a faint zig-zag impression at the gastro-oesophageal junction that demarcates the transition between the stratified squamous epithelium in the oesophagus and the intestinal epithelium of the gastric cardia (the squamocolumnar junction).
This results in the common endoscopic diagnosis of “irregular z-line.” The yield of biopsy of this area to determine the presence of specialized intestinal metaplasia is the subject of this report. Methods: The charts of all patients presenting for elective upper endoscopy at the Mayo Clinic Jacksonville between 7/1/03 and 10/31/03 were reviewed.
18 mar 2019 · We highlight the common anatomical landmarks of the upper gastrointestinal tract (Table 1, Figure 2) and endoscopic techniques for successful esophageal intubation, gastric retroflexion, duodenal access and tissue sampling using biopsy forceps.
This research presents a hybrid encoder–decoder-based model for segmenting healthy organs in the GI tract in biomedical images of cancer patients, which might help radiation oncologists treat...
23 cze 2019 · The Z line is an irregular serrated line that demarcates the squamocolumnar mucosal junction. The Z line can sometimes be recognized on double-contrast esophagograms as a thin radiolucent stripe in the distal esophagus with a characteristic zigzag appearance ( Fig. 26-2 ).
For a better understanding of the procedure, we present the standard landmarks of the upper-GI tract (Fig. 5) and typical GI lesions detected by MCE (Fig. ...
Histologically, the gastroesophageal junction has been defined as the point where there are no longer any submucosal esophageal glands or the proximal extent of the gastric oxyntic glands. Endoscopically, the junction has been defined as the squamocolumnar junction, or Z-line, and the proximal extent of the gastric mucosal folds.
