Title: Endoscopic Mucosal Resection of a 40 mm Flat Ascending Colon Polyp with a Duckbill Snare
Abstract: Endoscopic resection of large colon polyps should be preferred over a surgical approach as it is less invasive. However, endoscopic mucosal resection of large colon polyps can be technically challenging for the endoscopist. The technique of large polypectomy has been evolving with advances in endoscopy equipment, imaging, and the use of techniques such as raising the polyp by submucosal injection and performing polypectomy in the retroflexed position. In this article, some important aspects of the technique for endoscopic resection of a large flat colon polyp are demonstrated. This article is part of an expert video encyclopedia.
