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 …

Tunneling-free peroral endoscopic septotomy for Zenker diverticulum

Post written by Maria Manuela Estevinho, MD, and Rolando Pinho, MD, from the Department of Gastroenterology, Vila Nova de Gaia Espinho Hospital Center, Vila Nova de Gaia, Portugal. We report on a modified Zenker peroral endoscopic myotomy (Z-POEM) technique (tunneling-free) that was carried out on 4 patients. Initially, a mucosal incision was made over the septum …

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 …

EUS-guided drainage of a segment VI liver abscess using a lumen-apposing metal stent

Post written by Carlos Robles-Medranda, MD, from the Instituto Ecuatoriano de Enfermedades Digestivas (IECED), Guayaquil, Ecuador. We present a case study of an unilocular collection in the sixth segment of the liver that persisted after treatment with broad-spectrum antibiotic therapy. Because of comorbidities, full-dose anticoagulation, and high cardiovascular, surgical, and bleeding risks of percutaneous drainage, the …

Troubleshooting impaction of a pancreatoscopy-guided retrieval basket during pancreatic duct stone removal

Post written by Samuel Han, MD, MS, from The Ohio State University Wexner Medical Center, Columbus, Ohio, USA. We describe a case of pancreatoscopy-guided removal of a pancreatic duct stone. As electrohydraulic lithotripsy (EHL) was unsuccessful in fragmenting the large pancreatic duct stone, we used a cholangiopancreatoscopy-specific basket device to capture the stone. During removal of …
