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 …
Comparative diagnostic performance of different techniques for EUS-guided fine-needle biopsy sampling of solid pancreatic masses: a network meta-analysis
Post written by Antonio Facciorusso, MD, PhD, from the Gastroenterology Unit, Department of Surgical and Medical Sciences, University of Foggia, Foggia, Italy. In the last decade, several EUS fine-needle biopsy (FNB) sampling needles have been developed, and newer end-cutting FNB needles, which feature alterations of the cutting tip, have been found to outperform other needles in …
Auxiliary diagnosis of subepithelial lesions by impedance measurement during EUS-guided fine-needle biopsy
Post written by Yosuke Minoda, MD, PhD, from the Department of Medicine and Bioregulatory Science, Graduate School of Medical Sciences, Kyushu University, and the Department of Endoscopic Diagnostics and Therapeutics, Kyushu University Hospital, Fukuoka, Japan. This study presents a new method to differentiate a GI stromal tumor (GIST) from a non-GIST in gastric subepithelial lesions (SELs) …
Primary needle-knife fistulotomy versus rescue precut: a systematic review and meta-analysis of outcomes
Post written by Jay Bapaye, MD, from the Department of Internal Medicine, Rochester General Hospital, Rochester, New York, USA. Precut sphincterotomy is a technique used when attempts at gaining biliary access with the help of standard catheters, cannulotomes, and guidewires have failed. In our study, we tried to answer the question of how does a primary …

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 …
