Full-thickness resection closure using reopenable-clip over-the-line method inside a submucosal pocket
Post written by Tatsuma Nomura, MD, from Mie Prefectural Shima Hospital, Shima, Mie, Japan. We recently developed a new procedure known as full-thickness resection closure using a reopenable-clip over-the-line method inside a submucosal pocket (ROLM-SP) procedure. During this procedure, the first mucosal incision was made at 20 mm from the center, and a calibrated, small-caliber tip, …
EUS-guided choledochoantrostomy as an alternative for biliary decompression in malignant distal biliary obstruction with duodenal invasion
Post written by Ahmed Altonbary, MD, FRCP, from Mansoura Specialized Medical Hospital, Mansoura University, Mansoura, Egypt. We describe a case of unresectable pancreatic cancer with extrahepatic biliary obstruction and duodenal invasion that was successfully treated with a variant of EUS-guided biliary drainage by performing EUS-guided choledochoantrostomy (EUS-CAS). EUS-guided choledochoduodenostomy (EUS-CDS) is commonly performed for biliary decompression …
EUS-guided fine-needle biopsy sampling of solid pancreatic tumors with 3 versus 12 to-and-fro movements: a multicenter prospective randomized controlled study
Post written by Kosuke Takahashi, MD, PhD, from the Department of Gastroenterology and Hepatology, Graduate School of Biomedical Sciences, Nagasaki University, Nagasaki, Japan, and Ichiro Yasuda, MD, PhD, from the Third Department of Internal Medicine, University of Toyama, Toyama, Japan. In this study, a novel EUS-guided fine-needle biopsy sampling (EUS-FNB) needle enabled physicians to obtain sufficient …
Ex vivo nonbiomaterial gel-based model for endoscopic training
Post written by Ameya Deshmukh, DO, from the Department of Internal Medicine, Saint Louis University – SOM, St. Louis, Missouri, USA. EndoGel (Sunnarow Limited, Tokyo, Japan) is an ex vivo gel-based simulator that is designed to behave similarly to intestinal mucosa. It uses polyvinyl alcohol hydrogel materials, enabling this gel-based model to accurately mimic en vivo …

Spray coagulation as an alternative to argon plasma coagulation for bleeding portal hypertensive gastropathy
Post written by Sahaj Rathi, MD, DM, MRCP, from the Department of Hepatology, Post Graduate Institute of Medical Education and Research, Chandigarh, India. Noncontact thermoablation is often used for mucosal bleeding during endoscopy, as it has the advantage of thermal injury limited to superficial layers. Practically, argon plasma coagulation (APC) is the only modality most centers …
Detection and endoscopic classification of intraductal neoplasms of the bile duct by peroral cholangioscopy with narrow-band imaging (with videos)
Post written by Il Sang Shin, MD, PhD, Jong Ho Moon, MD, PhD, and Yun Nah Lee, MD, PhD, from the Digestive Disease Center and Research Institute, Department of Internal Medicine, SoonChunHyang University School of Medicine, Bucheon, Cheonan, and Seoul, Korea. Indirect diagnostic modalities such as CT, magnetic resonance imaging, and ERCP are sometimes unsatisfactory for …
Modified double-layered suturing for a mucosal defect after colorectal endoscopic submucosal dissection (Origami method) (with video)
Post written by Teppei Masunaga, MD, and Motohiko Kato, MD, PhD, from the Division of Research and Development for Minimally Invasive Treatment, Cancer Center, Keio University School of Medicine, Tokyo, Japan. Endoscopic defect closure techniques have been applied to reduce the incidence of adverse events after colorectal endoscopic submucosal dissection (ESD). This retrospective observational study aimed …
Editor’s Choice: Underwater versus conventional EMR of large nonpedunculated colorectal lesions: a multicenter randomized controlled trial
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 …
Precut papillotomy on a minor papilla followed by balloon papilloplasty to provide a complete pancreatic-duct drainage in tropical pancreatitis with reverse pancreas divisum
Post written by Rungsun Rerknimitr, MD, FRCP (London), FASGE, from Chulalongkorn University, Bangkok, Thailand. Our case is about a 10-year-old girl with known tropical chronic pancreatitis with mutation at the transition c.206C>T in exon 4 of the SPINK1 gene who underwent pancreatic sphincterotomy via major papilla with pancreatic stone extraction 6 months prior. The patient presented with a new episode of epigastric pain and elevation …
