Studies using high-resolution esophageal manometry suggests that in patients with reflux, even in the absence of HH, there is separation between both sphincters However, it is technically challenging and only indicated for BE segments with a length below 5 cm GEJ proximal of gastric foldssquamous-columnar junction Z lineand hiatal imprint. Despite emphasis on the importance of identifying the above-mentioned anatomical structures and measuring distance for the diagnosis of BE, lack of diagnostic consistency remains an esofato.
The hiatal imprint is also important to correctly identify hiatal hernia, a condition where the presence and length of columnar metaplasia may be more difficult to establish Anyway, no single protocol has been validated and established globally.

Epidemiology The incidence of BE has increased from paralleling the increase in endoscopic exams A critical review of the diagnosis and management of Barrett’s esophagus: Scand J Gastroenterol ; The progenitor cell originating these changes is poorly established, and a most accepted hypothesis involves the differentiation of a pluripotential cell at the basal layer of the esophageal epithelium The effect of antireflux surgery on esophageal carcinogenesis in fsofago with Barrett esophagus.
Surveillance of Barrett’s oesophagus: The SBE notion distance from the Z line to GEJ lower than 3 cm 68 is still a clinical dilemma regarding when and how biopsies should be obtained.
An essential factor to predict the risk of dysplasia and cancer development”. Journal of Clinical Pathology. LGD is characterized by preserved glandular architecture, and nuclei increased in both number and size that are usually elongated and stratified up to two thirds though never reaching the luminal third or pole of the cell, and never losing their perpendicular position regarding the basal membrane.
A major issue with anti-H 2 is the development of tachyphylaxis within the first week of therapy 93, Prominent nucleoli may be seen. Overall, the male to female ratio of Barrett’s esophagus is The presence of BE is not associated with gastric acid hypersecretion since no differences in basal acid output or gastrin-stimulated peak acid output have been found by controlled studies In rare cases, damage to the esophagus may be caused by swallowing a corrosive substance such as lye.
