Abstract

Introduction: Gastric polyps are seen 2–3% in all gastrointestinal endoscopic examinations. Hyperplastic polyps, the most common type of gastric polyps, are present 85–90% of cases. Giant villous tumors of the stomach are somewhat rare and the high incidence of malignant transformation of them requires prompt diagnosis. Giant gastric polyps can also cause gastrointestinal bleeding that leads to iron deficiency anemia or partial gastric outlet obstruction. All giant polyps must be resected endoscopically or surgically and still there are no marked

Summary

Introduction

Gastric polyps are seen 2–3% in all gastrointestinal endoscopic examinations. Hyperplastic polyps, the most common type of gastric polyps, are present 85–90% of cases [1]. Villous adenomas of the stomach are somewhat rare with approximately 100 cases only reported in literature and have tendency to undergo malignant transformation as high as 72% [2] They are frequently multiple and associated with other gastrointestinal neoplasms. Upper gastrointestinal endoscopy revealed a 6x7 cm diameter pedinculated polyp covered with irregular villous mucosa arising from the antrum of the stomach and which totally obstructed the entrance of the pyloric channel (Figures 1 and 2). This polyp was seen prolapsing into the bulbus of the duodenum causing gastric outlet obstruction.
