Helix tack for lumen-apposing metal stent fixation in single-session EUS-directed transgastric ERCP
Post written by Kambiz S. Kadkhodayan, MD, from the Center for Interventional Endoscopy, AdventHealth, Orlando, Florida, USA. We describe the use of a helix tack system to anchor the proximal flange of a lumen-apposing metal stent (LAMS) to the gastric pouch during a single-session EUS-directed transgastric ERCP (SS-EDGE). This video case also describes a reverse …

Computer-aided characterization of early cancer in Barrett’s esophagus on i-scan magnification imaging: a multicenter international study
Post written by Mohamed Hussein, MRCP, from the Department of Gastroenterology, Guy’s and St Thomas’ NHS Foundation Trust, London, United Kingdom. We aimed to develop a computer-aided characterization system that could support the diagnosis of dysplasia in Barrett’s esophagus on magnification endoscopy. We also strived to assess the speeds of the networks in making this …
Effect of ursodeoxycholic acid after self-expandable metal stent placement in malignant distal biliary obstruction: a propensity score–matched cohort analysis
Post written by Mitsuru Okuno, MD, PhD, from the Department of Gastroenterology, Gifu Municipal Hospital, Gifu, Japan. We reported on the evaluation of ursodeoxycholic acid (UDCA) for different self-expandable metal stent (SEMS) types in malignant distal biliary obstruction (MDBO) with a multicenter retrospective study design using propensity score—matched cohort analysis. The non-UDCA group had significantly …
Bile duct tissue acquisition by cholangioscopy-guided cryobiopsy technique: first-in-human application
Post written by Jan Peveling-Oberhag, MD, from the Department of Gastroenterology, Klinikum Stuttgart, Stuttgart, Germany. The cryobiopsy technique is a new method for tissue extraction that allows for extraction of high tissue amounts with a minimal diameter endoscopic instrument. Forceps biopsies through the very small working channel of a cholangioscope are oftentimes unrepresentative. In this …
Interobserver agreement of the modified Paris classification and histology prediction of colorectal lesions in patients with inflammatory bowel disease
Post written by Nayantara Coelho-Prabhu, MD, Associate Professor of Medicine from the Division of Gastroenterology and Hepatology, Mayo Clinic, Rochester, Minnesota, USA. This study was performed to assess the interobserver variability in application of the recommended Paris classification to describe the morphology of visible dysplasia in inflammatory bowel disease (IBD) colonoscopies. There is a lack of …
Utilization of methylene blue–based submucosal injection to identify residual neuroendocrine tumor in the colon after endoscopic biopsy sampling
Post written by Weina Jing, MD, and Kai Deng, MD, from the Department of Gastroenterology & Hepatology, West China Hospital, Sichuan University, Chengdu, Sichuan, China. This study provides a new way to find small residual neuroendocrine tumors. Submucosal staining assisted in the identification of minor lesions in the lamina propria of the mucosa. Neuroendocrine tumors of …
Successful planned piecemeal endoscopic resection using gel immersion and an over-the-scope clip for a lesion extensively extended into the colonic diverticulum
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 …
Underwater versus conventional EMR for nonpedunculated colorectal lesions: a randomized clinical trial
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 …
