Histopathological Changes in Stomach Wall at Sites Other than the Ulcer Site in Peptic Ulcer Disease and its Association with Helicobacter pylori

Introduction: A peptic ulcer (PU) is a break in the lining of the gastrointestinal tract, extending through to the muscular layer(muscularis mucosae) of the bowel wall. It is an endoscopic diagnosis. While they may technically appear anywhere in thegastrointestinal tract, they are most often located on the lesser curvature of the proximal stomach or the first part of the duodenum.Aim: This study aims to study the changes in stomach wall at sites other than the ulcer site in PU disease and to correlate theassociation of stomach wall changes with Helicobacter pylori infection.Materials and Methods: In this study, patients with duodenal ulcers diagnosed in endoscopy were included in the study. Duringan endoscopy, the stomach wall is examined and any changes in the stomach wall are noted. Endoscopically and biopsy fromtwo areas in the stomach are taken from antrum and body and sent to histopathological examination. Rapid urease test toconfirm the presence of H. pylori was done.Results: Sixty patients were included, 67% of patients were male, 82% of patients were positive in rapid urease test, 84%antrum was affected, and 50% in the body of the stomach was affected. The overall incidence of chronic atrophic gastritis isnearly 84.1% when compared to other types of lesions.Conclusion: Gastric antrum was the most common site for H. pylori than the body of the stomach. The presence of H. pyloriin the stomach wall is associated with active on chronic gastritis.
