Diagnosis and treatment of a biliary fistula to walled-off pancreatic necrosis
Post written by Erica Park, MD, from the Division of Gastroenterology, Hepatology, and Nutrition, Ohio State University Wexner Medical Center, Columbus, Ohio, USA. We describe a case of biliary obstruction from a walled-off pancreatic necrosis, for which the patient underwent EUS-guided cystduodenostomy for biliary decompression. The patient’s liver function tests results subsequently improved, which we initially …

Radiation exposure to patients undergoing conventional and novel endoscopy procedures
Post written by Anmol Singh, MBBS, and Venkata Akshintala, MD, from the Division of Gastroenterology and Hepatology, Department of Medicine, Johns Hopkins School of Medicine, Baltimore, Maryland, USA. Our study highlights the quantity of radiation exposure incurred during common and novel endoscopic procedures and elucidates the factors affecting it. There has been an upward trend in …
The Lambda stenting technique: a new approach to address EUS-guided biliary drainage–associated adverse events
Post written by Hiroki Sato, MD, PhD, Hidemasa Kawabata, MD, PhD, and Mikihiro Fujiya, MD, PhD, from the Division of Gastroenterology, Department of Internal Medicine, Asahikawa Medical University, Asahikawa, Hokkaido, Japan. We encountered 2 cases of stent migrations and 1 case with repeated cholangitis. In the first 2 cases, the metal stent inserted during the first …
Migrated lumen-apposing stent trapped within a pancreatic fluid collection: Forward-view EUS for the rescue!
Post written by Pradev Inavolu, MD, DM, Wladyslaw Januszewicz, MD, PhD, and Sundeep Lakhtakia, MD, DM, from AIG Hospitals and Asian Institute of Gastroenterology, Hyderabad, Telangana, India. We encountered a case of maldeployment of a lumen-apposing mental stent (LAMS) into the pseudocyst cavity with loss of access. Typically, such an adverse event necessitates a surgical intervention …
EUS-guided coil injection therapy in the management of gastric varices: the first U.S. multicenter experience (with video)
Post written by Ahmad Najdat Bazarbashi, MD, from Washington University in St. Louis School, St. Louis, Missouri, USA. The focus of this study was to evaluate the efficacy and safety profile of EUS-guided coil therapy for the management of gastric varices through a multicenter retrospective collaborative effort in the United States—the first of its kind. There …
Long-term outcomes after EUS-guided antegrade intervention for benign bilioenteric anastomotic stricture
Post written by Kazumasa Nagai, MD, PhD, from Tokyo Medical University, Tokyo, Japan. Bilioenteric anastomotic stricture (BES) is a significant adverse event after hepaticojejunostomy. Recently, EUS-guided antegrade intervention (EUS-AI) has been developed in cases of balloon enteroscopy–assisted ERCP failure. Several reports have demonstrated the efficacy and safety of EUS-AI. However, the results of these studies were …
Two clues make a proof: EUS-directed transgastric ERCP in twice-surgically altered anatomy—Roux-en-Y gastric bypass conversion of a sleeve gastrectomy
Post written by Giuseppe Vanella, MD, from the Pancreatobiliary Endoscopy and Endosonography Division, IRCCS San Raffaele Institute, Milan, Italy. In the realm of endoscopy, the advent of lumen-apposing metal stents (LAMSs) has paved the way for innovative solutions to challenges once considered insurmountable. One such breakthrough is the technique known as EUS-directed transgastric ERCP (EDGE), which …
Ultrathin endoscope equipped with ultrasonic miniprobe for upper GI US in a porcine model
Post written by Hanchao Pan, MM, from the Department of Gastroenterology, First Affiliated Hospital of Soochow University, Suzhou, China. A 1.4-mm diameter EUS miniprobe catheter system (20 MHz and 30 MHz) was designed and fabricated. This system can be compatible with the existing ultrathin gastroscope working channel. Miniprobe ultrasonography through the ultrathin gastroscope can be realized …
