Post written by Mayenaaz Sidhu, MBBS, from the Department of Gastroenterology and Hepatology, Westmead Hospital, Sydney, Australia. This study was conducted to evaluate the incremental benefit of dye-based chromoendoscopy (DBC) to predict the risk of submucosal invasive cancer (SMIC) for large nonpedunculated colorectal polyps (LNPCPs) among independent observers. Real-time optical evaluation of the lesion’s surface …

Post written by Thomas R. McCarty, MD, and Hiroyuki Aihara, MD, PhD, from the Division of Gastroenterology, Hepatology and Endoscopy, Brigham and Women’s Hospital, Harvard Medical School, Boston, Massachusetts, USA. In this video presentation, we describe a case of successful en bloc resection of a 60-mm laterally spreading tumor granular type (LST-G) rectal lesion using …
Width and depth of resection for small colorectal polyps
Post written by Sho Suzuki, MD, PhD, from the Division of Gastroenterology and Hepatology, Department of Medicine, Nihon University School of Medicine, Tokyo, Japan. We conducted this prospective, randomized, exploratory study to investigate the resection width and depth achieved by cold snare polypectomy (CSP) for small colorectal polyps compared to those achieved by hot snare …

Volume of surgery for benign colorectal polyps in the last 11 years
Post written by Maxime E.S. Bronzwaer, MD, from the Department of Gastroenterology and Hepatology, Academic Medical Center, University of Amsterdam, Amsterdam, the Netherlands. Over the past decade endoscopic resection techniques, such as piecemeal endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), have progressed significantly to treat large and complex non-pedunculated colorectal polyps. Endoscopic resection …

History of Diminutive and Small Colorectal Polyps
Post written by Jasper L.A. Vleugels from the Academic Medical Center, University of Amsterdam, Amsterdam, the Netherlands. This study explored the natural history of diminutive polyps that were left without resection and were followed up. At a certain point, I was in the endoscopy room, and the patient undergoing colonoscopy asked why these diminutive polyps …
