Abstract
Objective: to improve the diagnosis of gastroesophageal reflux disease and its complications. Materials and methods: clinical and endoscopic studies were performed on 1052 patients, 110 of them healthy, 722 - with gastric ulcer and duodenal ulcer, after Billroth II stomach resection, with a hiatus hernia, gallstone disease, etc., 210 children. Studied 100 macropreparations of the esophageal-gastric junction and 70 longitudinal histotopograms from patients who died from diseases not related to diseases of the gastrointestinal tract, histotopograms of 10 cases with esophageal adenocarcinoma and esophageal-gastric junction. Results: The location of the Z-line is individually variable, the range is limited to two levels: up to 40 mm above and 18 mm below the outlet of the cardia. The presence of a mucous membrane with a cylindrical epithelium in the distal esophagus is a variant of the norm. In the area of the Z-line in 70% of cases there is a duplication at a distance of 10 mm, consisting of a mucous membrane with a stratified squamous epithelium, covering the mucous membrane with the gastric epithelium. High Helicobacter infection of the mucous membrane with gastric epithelium was detected, its pre-neoplastic changes in adults (17.2%), in children (10.9%) and Barrett’s esophagus are often found in mild degrees of esophagitis, and there are also indirect signs of HP in the esophagus. Conclusions: The presence of a mucous membrane with a cylindrical epithelium in the esophagus up to 40 mm above the outlet of the cardia is a variant of the norm. In the area of the Z - line there is in 70% of cases duplication at a distance of 10 cm, consisting of a mucous membrane with a stratified squamous epithelium, under which there is a mucous membrane with a gastric epithelium, and a step biopsy is required to diagnose changes in it. The presence of HP in the mucous membrane of gastro-esophageal junction has indirect endoscopic signs, contributes to the development of pre-neoplastic changes of the mucous membrane, which in most cases are found in mild degrees of esophagitis, which requires antihelicobacter therapy.
