Abstract
PURPOSE OF REVIEW: Standard endoscopic polypectomy is a powerful technique to remove most polyps found in the gastrointestinal tract. However, a small percentage of polyps can be classified as difficult, based on size, location, and/or configuration. Traditionally, these difficult polyps were referred for surgical segmental colectomy. Recently, with advancements in endoscopic techniques and accessories, a majority of these difficult polyps are now able to be completely resected using entirely endoscopic techniques. RECENT FINDINGS: Endoscopic techniques and accessories have been evolving during recent years, including increased dissemination of techniques of endoscopic submucosal dissection to the western hemisphere. In addition to refinement of endoscopic techniques, there has been increased interest in developing improved endoscopic accessories, including novel submucosal injectate with auto-dissecting properties, to improve safety and efficiency of endoscopic resection of difficult polyps. SUMMARY: This article will review currently available techniques and strategies for successful endoscopic resection for difficult polyps.
