Post written by Britt B.S.L. Houwen, MD, from the Department of Gastroenterology and Hepatology, Amsterdam University Medical Centers, location Academic Medical Center, University of Amsterdam, Amsterdam, the Netherlands. Implementation of the optical diagnosis strategy for diminutive colorectal polyps by endoscopists and computer-aided diagnosis (CADx) systems is hampered as the current competence criteria [PIVI] are impractical …

Efficacy and histologic accuracy of underwater versus conventional endoscopic mucosal resection for large (>20 mm) colorectal polyps
Post written by Saurabh Chandan, MD, from the Gastroenterology and Hepatology, CHI Creighton University Medical Center, Omaha, Nebraska, USA. Underwater endoscopic mucosal resection (U-EMR) is a simple and easy-to-learn technique for resection of colorectal lesions. It eliminates the need of using submucosal injection to “lift” the lesion prior to resection. The main aim of our …
Colorectal cancer in 18- to 49-year-olds: rising rates, presentation, and outcome in a large integrated health system
Post written by Nimish Vakil, MD, from the Department of Medicine, University of Wisconsin School of Medicine and Public Health, Madison, and the Department of Gastroenterology, Advocate Aurora Health, Milwaukee, Wisconsin, USA. Colon cancer is rising in young people and the cause is unknown. There is little information on outcomes in this group. Colorectal cancer …
Combination of a dynamic rigidizing overtube and a novel injectable needle-type knife to facilitate colorectal endoscopic submucosal dissection
Post written by Martin Coronel, MD, and Phillip S. Ge, MD, from the Department of Gastroenterology, Hepatology and Nutrition, The University of Texas MD Anderson Cancer Center, Houston, Texas. A 66-year-old man was referred for endoscopic resection of a 35-mm laterally spreading tumor at the hepatic flexure (Paris IIa+Is). A previous EMR attempt was unsuccessful …
Evaluating learning curves and competence in colorectal EMR among advanced endoscopy fellows
Post written by Dennis Yang, MD, from the Division of Gastroenterology and Hepatology, University of Florida, Gainesville, Florida, USA. The aim of this multicenter prospective pilot study was to evaluate colorectal endoscopic mucosal resection (EMR) training among advanced endoscopy fellows using a novel assessment tool. Despite the broad application of colorectal EMR, markers of training …
Postpolypectomy bleeding of colorectal polyps in patients with continuous warfarin and short-term interruption of direct oral anticoagulants
Post written by Hideaki Harada, MD, from the Department of Gastroenterology, New Tokyo Hospital, Chiba, Japan. Our study aimed to clarify the risk of postpolypectomy bleeding (PPB) after endoscopic snare resection of colorectal polyps in patients receiving continuous warfarin and 1-day cessation of direct oral anticoagulants (O-DOACs) because the evidence for use of continuous anticoagulants …
Optical diagnosis of colorectal polyps: a randomized controlled trial comparing endoscopic image-enhancing modalities
Post written by Roupen Djinbachian, MD, from the Division of Internal Medicine, Montreal University Hospital Center (CHUM) and Montreal University Hospital Research Center (CRCHUM), Montreal, Quebec, Canada. The focus of this study was to compare a novel endoscopic image-enhancing modality (Optivista) to an existing precursor (iScan) for optical colorectal polyp diagnosis in a randomized controlled …
Evaluation of colorectal endoscopic submucosal dissection using a multifunctional snare
Post written by Jun Arimoto, MD, PhD, from the Department of Gastroenterology, Omori Red Cross Hospital, Tokyo, Japan. In this study, we evaluate the safety and efficacy of colorectal ESD using the SOUTEN snare. Although the SOUTEN snare was introduced for hybrid ESD, hybrid ESD involves partial submucosal dissection. So, we thought that “SOUTEN-ESD,” mean …
Triple-loop clip for the traction-assisted colorectal ESD
Post written by Shuichi Miyamoto, MD, PhD, from the Department of Gastroenterology and Hepatology, Hakodate Municipal Hospital, Hakodate, and the Department of Gastroenterology and Hepatology, Hokkaido University Faculty of Medicine and Graduate School of Medicine, Sapporo, Japan. Recently, the effectiveness of traction-assisted ESD has been reported, and there are various devices for applying countertraction. These …

A recurrent lesion with severe fibrosis of colorectal ESD using the combination of pocket-creation method and traction device
Post written by Naohisa Yoshida, MD, PhD, from the Department of Molecular Gastroenterology and Hepatology, Graduate School of Medical Science, Kyoto Prefectural University of Medicine, Kyoto, Japan. Colorectal endoscopic submucosal dissection (ESD) is spreading in the world, but there are still several problems such as poor manipulation, breathing movement, severe fibrosis, and long procedure time. …
