The Role of Endoscopy in the Management of Premalignant and Malignant Conditions of the Stomach

This clinical practice guideline discusses the use of endoscopy in patients with malignant and premalignant conditions of the stomach including gastric polyps, gastric intestinal metaplasia (GIM), pernicious anemia, gastric carcinoid tumours, adenocarcinoma, mucosa-associated lymphoid tissue (MALT) lymphoma, and GI stromal tumours (GISTs). Surveillance endoscopy, staging ultrasound, biopsy, polypectomy, resection (surgical and endoscopic), and open gastrojejunostomy are discussed. Outcomes of interest include risk factors for dysplasia and gastric cancer, as well as survival rate, accuracy of staging techniques, and treatment complication rate.
