Evaluation of Antral Biopsies Obtained in Endoscopically Normal Esophagogastroduodenoscopy: A Retrospective Cohort Study

Le résumé fourni par la source

BACKGROUND: The requirement for routine biopsy sampling in esophagogastroduodenoscopy (EGD) with normal endoscopic findings is a subject of debate. In this study, patients who had normal endoscopic findings in EGD and underwent biopsy sampling were retrospectively analyzed. METHODS: This single-center retrospective cohort study included 671 patients who underwent EGD between 2021 and 2023 in the Sisli Hamidiye Etfal Training and Research Hospital Surgical Endoscopy Unit. All patients had normal endoscopic findings and a sampling biopsy was performed on all patients included. Patients were evaluated based on demographic and clinicopathologic findings. This study was registered to ClinicalTrials.gov (NCT06269380). RESULTS: Two hundred sixty patients (38.7%) have abnormal histopathologic findings. Helicobacter pylori positivity was detected in 200 (29.8%) patients. Intestinal metaplasia (IM) was present in 80 of 260 patients (30.8%). The frequency of IM was higher in older age groups and cases with mild gastritis ( P <0.001). The frequency and severity of gastritis were associated with increased H. pylori positivity and density ( P <0.001). CONCLUSIONS: The biopsy sampling may contribute to the diagnosis and treatment process in cases where normal endoscopic findings are observed during EGD.
