Post written by Satoki Shichijo, MD, PhD, from Osaka International Cancer Institute, Osaka, Japan. We performed underwater EMR for a 20-mm Paris Ip polyp at the terminal ileum. The lumen of the terminal ileum was infused with normal saline through the waterjet of the colonoscope. This made the polyp float and permitted thorough inspection despite the …

GIE Associate Editor Thiruvengadam Muniraj, MD, highlights this article from the May issue: “Underwater versus conventional EMR of large nonpedunculated colorectal lesions: a multicenter randomized controlled trial” by Joaquín Rodríguez Sánchez, MD, PhD, et al. This study is valuable because it explores alternate options for endoscopic submucosal dissection (ESD). This is one of the very few randomized …
Post written by Tomoaki Tashima, MD, PhD, from the Department of Gastroenterology, Saitama Medical University International Medical Center, Saitama, Japan. A 78-year-old man was referred to our institute for treatment of a flat elevated (20-mm diameter) lesion observed around and within the diverticulum near the ileocecal valve of the ascending colon. The lesion border was marked via an …
Post written by Luciano Lenz, PhD, from the Instituto do Cancer do Estado de São Paulo, and Fleury Medicina e Saude, São Paulo, São Paulo, Brazil. The focus of our study was to compare recurrence after underwater endoscopic mucosal resection (UEMR) and after conventional endoscopic mucosal resection (CEMR) for naïve nonpedunculated lesions. This study is important …
Post written by Yushi Kawakami, MD, from the Department of Gastrointestinal Oncology, Osaka International Cancer Institute, Osaka, Japan. It was suspected that a 75-year-old woman had advanced infiltrative gastric cancer. However, endoscopic forceps biopsy specimens did not reveal adenocarcinoma. She was referred to our institute for further examination and treatment. To obtain sufficient submucosal specimens, underwater …

Post written by Kazunori Takada, MD, and Kinichi Hotta, MD, from the Division of Endoscopy, Shizuoka Cancer Center, Shizuoka, Japan. Compared with conventional EMR, endoscopic submucosal dissection (ESD) provides a higher en-bloc resection rate and a lower local recurrence rate for large lesions. However, ESD is technically demanding and associated with a higher risk of adverse …
Post written by Kayla M. Hartz, DO, from the Department of Internal Medicine, Penn State Health Milton S. Hershey Medical Center, Hershey, Pennsylvania. These are 2 cases in which hemostatic spray was used as a bail-out method for hemostasis when other standard methods failed. These cases show the value in using a hemostatic spray as …
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 …
Dr. Doug Adler, GIE Senior Associate Editor, chats with Dr Saurabh Chandan about his article "Efficacy and histologic accuracy of underwater versus conventional endoscopic mucosal resection for large (>20 mm) colorectal polyps: a comparative review and meta-analysis" from the September issue. Our guest for the September 2021 GIE Podcast is Dr Saurabh Chandan, Assistant Professor, …
