Editor’s Choice: Computer-aided characterization of early cancer in Barrett’s esophagus on i-scan magnification imaging: a multicenter international study
GIE Associate Editor Seiichiro Abe, MD, PhD, FASGE, FJGES, highlights this article from the April issue: “Computer-aided characterization of early cancer in Barrett’s esophagus on i-scan magnification imaging: a multicenter international study” by Mohamed Hussein, MRCP, et al. Magnifying virtual chromoendoscopy is helpful in differentiating between dysplastic and nondysplastic lesions in patients with Barrett’s esophagus (BE), …
Artificial intelligence for detecting and delineating the extent of superficial esophageal squamous cell carcinoma and precancerous lesions under narrow-band imaging (with video)
Post written by Bing Hu, MD, from the Department of Gastroenterology, West China Hospital, Sichuan University, Chengdu, Sichuan, China. The focus of this study was to train an artificial intelligence (AI) system that could detect and delineate the extent of superficial esophageal squamous cell carcinoma (ESCC) and precancerous lesions under nonmagnified narrow-band imaging (NBI) and to …
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 …
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 …
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 …
Prophylactic EUS-guided gallbladder drainage prevents acute cholecystitis in patients with malignant biliary obstruction and cystic duct orifice involvement: a randomized trial (with video)
Post written by Carlos Robles-Medranda, MD, from the Instituto Ecuatoriano de Enfermedades Digestivas, Guyaquil, Ecuador. This study focuses on the benefits of prophylactic EUS-guided gallbladder drainage (EUS-GBD) in patients with unresectable malignant biliary obstruction (MBO) and occlusion of the orifice of the cystic duct (OCD). Although acute cholecystitis (AC) will not always develop in patients with …
Closure of large mucosal defects for prevention of strictures after duodenal endoscopic submucosal dissection (with video)
Post written by Yoko Kubosawa, MD, from the Division of Gastroenterology and Hepatology, Department of Internal Medicine, and the Division of Research and Development for Minimally Invasive Treatment, Cancer Center, Keio University School of Medicine, Tokyo, Japan. We analyzed the incidence of post–endoscopic submucosal dissection (ESD) strictures after wide-field duodenal ESD. Although it is known that …
Motorized spiral enteroscopy versus double-balloon enteroscopy: a case-matched study
Post written by Ravishankar Asokkumar, MBBS, FRCP, FASGE, from the Department of Gastroenterology and Hepatology, Singapore General Hospital, and the Division of Medicine, DUKE-NUS Graduate Medical School, Singapore. Evaluation of the small intestine can be tedious and challenging because of its anatomical nature. For a long time, double-balloon enteroscopy (DBE) has been considered the gold standard …
