ABSTRACT: Introduction: The gastric polyp is a tumor protruding into the gastric lumen. It is asymptomatic most often with a risk of malignant degeneration closely related to its histological nature. These data are very rare in Africa. Objectives: Reporting the frequency and endoscopic and histological characteristics of gastric polyps in the digestive endoscopy center of Aristide Le Dantec hospital in Dakar. Patients and methods: This was a retrospective study carried out in the digestive endoscopy center of Aristide Le Dantec Hospital in Dakar from January 2012 to December 2016. We have included all patients with one or more gastric polyps coupled with histological findings available. Results: There were 60 patients with gastric polyps, hence a prevalence of 0.8%. We included 37 patients. Their mean age was 46 years [21 years - 75 years]. The sex-ratio was 0.48. Epigastralgia was the most frequent endoscopic indication (51.3%). The polyp was unique in 26 patients (70.3%) with an average size of 6.87 mm [2 - 15 mm]. Polyps were sessile in 31 cases (83.8%) and pediculate in 6 cases (16.2%). They were most often in the antrum (51.4%). Antral erosions (13.5%) and fundic atrophy (13.5%) were the main associated endoscopic lesions. These were hyperplastic polyps in 27% of cases and adenoma in 16.2% of cases. Chronic atrophic gastritis (10.8%) and intestinal metaplasia (10.8%) were the main histological lesions associated with polyps. Helicobacter pylori (Hp) were present in 17 patients (45.9%). Conclusion: The prevalence of gastric polyps is 0.8% in the endoscopy center of Aristide Le Dantec hospital. They are usually hyperplastic or adenomatous.
