Suprapapillary placement of plastic versus metal stents for malignant biliary hilar obstructions: a multicenter, randomized trial
Post written by Yoshihide Kanno, MD, from Sendai City Medical Center, Sendai, Japan. This study focused on the outcomes of the suprapapillary placement of plastic versus metal stents for unresectable malignant hilar obstructions. No randomized studies had evaluated the outcomes of suprapapillary plastic stents in comparison with metal stents. The removability of plastic stents is a …
Dilation balloon-occlusion technique for EUS-guided gastrojejunostomy
Post written by Samuel Han, MD, from The Ohio State University Wexner Medical Center, Columbus, Ohio, USA. In this video with 2 cases, we describe a technique for performing an EUS-guided gastrojejunostomy using commonly available endoscopic devices, including an 18- to 20-mm dilation balloon (CRE Balloon Dilatation Catheter; Boston Scientific, Marlborough, Mass, USA). Upon identifying the site …

Predictors of stricture after non-circumferential endoscopic submucosal dissection of the esophagus and single-dose triamcinolone injection immediately after the procedure
Post written by Muneaki Miyake, MD, from the Department of Gastrointestinal Oncology, Osaka International Cancer Institute, Osaka, Japan. The focus of our study was to identify predictors of stricture after endoscopic submucosal dissection (ESD) of the esophagus with local triamcinolone (TA) injection. Local TA injection is widely used to prevent stricture formation after ESD of the …
Loop-and-let-go technique for the management of symptomatic large colonic lipoma
Post written by Syedreza “Reza” Haider, MD, MBA, from Washington University School of Medicine, St. Louis, Missouri, USA. In this video case, we present the successful endoscopic removal of a large colonic lipoma using the loop-and-let-go technique. The patient, a 69-year-old woman, had been experiencing intermittent bloating, abdominal pain, and constipation. During colonoscopy, a 50-mm …
