AGA Clinical Practice Update on Management of Gastric Polyps: Expert Review

This Clinical Practice Update (CPU) expert review will advise clinicians on the diagnosis and management of gastric mucosal polyps. Gastric polyps are raised epithelial lesions of the gastric mucosa that can arise from various mucosal alterations and perturbations, including mucosal hyperplasia, adenoma, fundic gland proliferation, and enterochromaffin-like cell proliferation. Current guidance on the management of gastric polyps remains limited. This CPU provides a framework for understanding the natural history and epidemiology of gastric polyps and advises on best practices for the endoscopic detection and classification of gastric polyps, the endoscopic resection of gastric polyps, and endoscopic surveillance following resection. Because gastric polyps often occur within a field of altered gastric mucosa (eg, mucosal atrophy, pseudo-pyloric and intestinal metaplasia), we will advise on best practices for the sampling and surveillance of mucosal pathology giving rise to gastric polyps. This CPU is intended to complement other documents issued by the American Gastroenterological Association (AGA) Institute on gastric neoplastic and pre-neoplastic lesions, including the clinical practice guidelines on management of gastric intestinal metaplasia, as well as AGA CPUs on atrophic gastritis, high-quality upper endoscopy, and screening and surveillance of individuals at increased risk for gastric cancer.
