Long term outcomes of sporadic large fundic gland polyps: a single-center experience

Abstract

Background and study aims Sporadic fundic gland polyps (FGP) are the most common type of gastric polyp, reported in 0.8%–1.9% of patients undergoing Esophagogastroduodenoscopy (EGD). Data on long-term outcomes of large FGP is limited. We aim to study the natural history of sporadic large (≥ 10 mm) FGPs. Patients and methods All adults who underwent EGD for any indication from April 2014 to December 2019 at a tertiary care center were retrospectively assessed, and patients with FGP (≥10mm) were identified. Data on baseline characteristics and long-term outcomes were recorded. Follow-up data were recorded for patients who underwent repeat endoscopy to evaluate for rates of dysplasia and cancer. Results A total of 4,000 patients with a diagnosis of FGP were screened and 132 large, biopsy-proven FGPs were included in the final analysis. The most common indication for EGD was gastroesophageal reflux disease (61%). During a follow-up period of 3.2 years, the rate of dysplasia, was 4.0%. Subgroup analysis based on size (10–19 mm and ≥ 20 mm) showed no significant difference in overall outcomes. Conclusion Repeat EGDs for surveillance should not be routinely performed since large (≥10 mm) sporadic FGPs are mostly benign without significant malignant potential.
