Analysis of the grade of esophagitis, chromendoscopical and histological findings of esophagus in patients with gastroesophageal reflux disease before and after the therapy

Background/Aim. The symptoms of gastroesophageal reflux desease (GERD) are among the most common complaints for which patients are indicated for visiting gastroenterologist. It occurs as a result of the effect made by gastric reflux contents that moves into the esophagus. The prevalence of all forms of GERD is 40%. The aim of this study was to analyze the grade of esophagitis, chromendoscopical and histological findings of esophagus in patients with GERD before and after the therapy. Methods. A prospective study included 90 patients with symptoms of GERD, divided into 2 groups depending on whether they had endoscopic signs of gastroezophageal reflux (group ERD), or not (group NERD). All the patients had esophagogastroduodenoscopy, chromoendoscopy staining, test for Helicobacter pylori and histological findings of the esophagus. In the patients with Helicobacter pylori infection eradication therapy was done. Results. Esophagitis-B level was present in most of the patients. Among the groups, roughly the same number responded to positive findings on chromoendoscopy. After the therapy, chromoendoscopy was significantly negative in both groups of the patients comparing to chromoendoscopy before the therapy (p = 0.00001). Multiplication and elongation of papilla, basal cell hyperplasia, vascular dilatation, increasing of mitotic activity and the presence of polymorphonuclear leukocyte cells were statistically more frequent histological findings in the group ERB compared to the group NERB. After the therapy, the patients in both groups had statistically less histological findings of appropriate esophageal parameters. Conclusion. Chromoendoscopy combined with the standard endoscopy increases the sensitivity and specificity for reflux disease. Histology in the reflux disease is associated with endoscopic and clinical findings so that the localization of taking biopsies and histological criteria of pathohistological changes must be clearly defined. Multiplication and elongation of papilla, basal cell hyperplasia and the presence of polymorphonuclear leukocytes are the most relevant criteria in the diagnosis NERD.
