Abstract: |
Examination of the stomach by upper endoscopy (EGD) often results in the incidental finding of gastric polyps or thickened gastric folds. Gastric polyps have been identified in 6% to 8% of all upper endoscopy exams. Most series report that the most common type of polyp encountered is the fundic gland polyp (77% to 80%) followed by the hyperplastic polyp (17% to 19%), though series differ through time and based on the series of patients being evaluated. Generally, patients with gastric polyps are asymptomatic, but polyps may cause clinical manifestations including gastrointestinal bleeding, iron deficiency anemia, and gastric outlet obstruction. Many of these lesions are benign, whereas others have malignant potential; understanding and recognizing the various diagnoses and malignant risk may impact endoscopic treatment, future management, and surveillance recommendations. Gastric polyps are generally defined as lesions in the lumen of the stomach with protrusion above the mucosal plane. These lesions may be epithelial or subepithelial at their presentation. This chapter reviews the most common etiologies of epithelial gastric polyps and discusses the endoscopic approach to management of these lesions. At the conclusion of this chapter, we discuss the evaluation of thickened gastric folds and outline the endoscopic approach to these entities. © 2019 Elsevier Inc. All rights reserved. |
