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 …

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 …

Effect of referral pattern and histopathology grade on surgery for nonmalignant colorectal polyps

Post written by Dennis Yang, MD, from the Division of Gastroenterology and Hepatology, University of Florida, Gainesville, Florida, USA. The incidence of surgery for nonmalignant colorectal polyps has continued to rise. We aimed to evaluate referral patterns and factors associated with surgery for nonmalignant colorectal polyps at a large tertiary care center. Endoscopic resection should …

Impact of submucosal saline solution injection for cold snare polypectomy of small colorectal polyps

Post written by Yuichi Shimodate, MD, from the Department of Gastroenterology and Hepatology, Kurashiki Central Hospital, Okayama, Japan. We compared the complete resection, which was defined if muscularis mucosa in the resected specimen was present under the tumor along more than 80% of the tumor’s horizontal dimension, rates of cold snare polypectomy with submucosal saline …
