An esophageal Z-line is irregular if it does not correctly join with the gastroesophageal junction at the base of the esophagus. Barrett's esophagus is typically diagnosed if the ultrasound reveals an irregular Z-line, but doctors usually conduct biopsies to detect the presence of intestinal cells in the esophagus mucosa.


Normal variation. The z-line, where the esophagus lining connects to the stomach lining varies quite a bit from person to person. Not everyone has a straight circle -- that's why it's called the "z"-line, because an irregular border is normal.


The findings are: multiple ulcers, gastritis, and an irregular z-line. I'm not too concerned about the ulcers since the medicines I was prescribed and a few minor changes to my diet should help take care of those, but I'm worried about the irregular z-line and what it would mean if the biopsy tests come out "positive".


The Z-line, as you can tell from its name, is quite irregular and that is entirely normal. Often when people get heartburn, we see more irregularities of the Z-line, or we see inflammation or irritation above the Z-line in the esophagus.


"The line at which the columnar epithelium transitions to the squamous epithelium (i.e., the squamocolumnar junction) is known as the Z-line. Normally, the Z-line corresponds to the gastroesophageal junction. In patients with Barrett’s esophagus, the columnar epithelium extends proximally up the esophagus." The Z-line can also be irregular if ...


Barrett's esophagus is a complication of chronic gastroesophageal reflux disease (GERD). GERD is the reflux of acidic fluid from the stomach into the esophagus, and is classically associated with heartburn. Learn more about Barrett's estophagus, including symptoms and causes.


Barrett's esophagus is thought to be caused by long-standing gastroesophageal reflux disease (GERD), which causes stomach contents to back up into the esophagus. In Barrett's esophagus, tissue in the tube connecting your mouth and stomach (esophagus) is replaced by tissue similar to the intestinal lining.


In some instances, the endoscopist may have observed an 'irregular, 'jagged or 'wavy Z-line that may or may not have been noted to be slightly proximally displaced from the anatomic gastroesophageal junction, and which indicated to the endoscopist the presence of a short (or more appropriately, ultrashort) segment of Barrett esophagus.


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) .


Hi judy56, Hiatus hernia is a condition in which part of the stomach slips in to the chest cavity causing discomfort. The stomach and the esophagus have different linings. The junction of these two is called the 'Z' line. I would like to know the biopsy report before commentinng further.
