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 …
Clinical utility of cricopharyngeal distensibility measurements during endoscopic myotomy for Zenker’s diverticulum
Post written by Linda Yun Zhang, MBBS, FRACP, from the Department of Gastroenterology & Hepatology, St George Hospital, Sydney, New South Wales, Australia. Flexible endoscopic cricopharyngeal myotomy allows minimally invasive treatment of patients with Zenker’s diverticulum. Despite its wide uptake there is a substantial retreatment rate, which is at least partly due to the lack …
