Endoscopic Mucosal Resection with Band Ligation for Two Cases of Gastric Flat Adenoma

Abstract

The gastric adenomas could be premalignant lesions and they should be removed as possible, especially in eases with its size aver 2cm. The gastric adenomas can be removed by the various endoscopic methods. Endoscopic polypectomy has been widely used for the treatment of benign and malignant polyps with the advent of technical improvement. Polypectomy with snare and electrocautery is mainly used for pedunculated polyps, but sessile polyps pose some technical difficulties and occasionally cause serious gastrointestinal hemorrhage or perforation. We resected two cases of gastric flat adenoma using Stiegman-Goff ligator used in endoscopic variceal ligation to make flat adenoma as semipedunculated form, and also to decrease the risk of bleeding. After ligation, we successfully removed it with conventional snare polypectomy. We recognized that endoscopic mucosal resection with band ligation can be used for the removal of sessile polyps or flat adenioma with ease, safety and no bleeding.
