Digital single-operator cholangioscopy for difficult anastomotic biliary strictures in living donor liver transplant recipients after failure of standard ERCP: SPYPASS-2 study (with videos)
Post written by In Rae Cho, MD, and Sang Hyub Lee, MD, PhD, from the Department of Internal Medicine and Liver Research Institute, Seoul National University College of Medicine, Seoul, South Korea. Anastomotic biliary strictures (ABSs) are a major adverse event after living donor liver transplantation (LDLT) and often difficult to treat with standard ERCP alone. The SPYPASS-2 study evaluated …
Directional movement guide for digital single-operator cholangioscopy system
Post written by Justin Ryan L. Tan, MD, from the Section of Gastroenterology, Chinese General Hospital and Medical Center, Manila, Philippines, and Weigang Gu, MD, from the Department of Gastroenterology, Affiliated Hangzhou First People's Hospital, Hangzhou, China. Although cholangioscopy has undergone increasing therapeutic applications, standardized training remains a significant challenge. Our team has focused on simplifying device …

Virtual indigo carmine chromoendoscopy images: a novel modality for peroral cholangioscopy using artificial intelligence technology (with video)
Post written by Ryosuke Sato, MD, and Kazuyuki Matsumoto, MD, PhD, from the Department of Gastroenterology and Hepatology, Okayama University Hospital, Okayama, Japan. Our study focused on developing and evaluating a novel imaging technique that combines artificial intelligence with peroral cholangioscopy to improve visualization of biliary strictures. We used cycle-consistent adversarial network (CycleGAN) technology to convert standard …
Detection of residual stones by peroral direct cholangioscopy in patients with intrahepatic stones after hepaticojejunostomy: a prospective study (with video)
Post written by Kazuyuki Matsumoto, MD, PhD, from Okayama University Hospital, Okayama, Japan. Radiographic confirmation of the presence of stones remains a challenge in the treatment of intrahepatic bile duct stones in patients after hepaticojejunostomy (HJ). Peroral direct cholangioscopy (PDCS) enables direct observation of the bile duct and is useful for detecting and removing residual stones. However, its …
Adverse events of the single-operator cholangioscopy system: a Manufacturer and User Facility Device Experience database analysis
Post written by Saurabh Chandan, MD, from the Creighton University School of Medicine, Omaha, Nebraska, USA, and the Center for Interventional Endoscopy, Advent Health, Orlando, Florida, USA. The primary aim of our study was to assess and report all adverse events (AEs), including those device- and patient-related, associated with the single-operator cholangioscopy (SOC) system (SpyGlass; Boston …
Cholangioscopy as a rescue for a post-cholecystectomy adherent stone formed around a migrated surgical clip in the common bile duct
Post written by Chukwunonso Ezeani, MD, from Baton Rouge General Medical Center, Baton Rouge, Louisiana, USA. This is a case of an 88-year-old woman with a history of cholecystectomy 30 years prior who presented with acute-onset right upper quadrant pain, nausea, and vomiting. Laboratory and imaging data were consistent with choledocholithiasis, with the bile duct measuring …
Cholangioscopy-guided tunneling and coaxial stenting of a large choledocholithiasis: a novel approach to mechanical lithotripsy
Post written by Abdulrahman Qatomah, MBBS, from the Department of Gastroenterology and Hepatology, McGill University, Montreal, Quebec, Canada. A large common bile duct stone was found in a patient with cholangitis. The stone was difficult to manage using the conventional ERCP method. Sessions of cholangioscopy-guided lithotripsy also failed to achieve stone fragmentation. We wanted to highlight …
Cholangioscopy-guided salvage retrieval of a migrated stent at a hepaticojejunostomy anastomosis using a colonoscope
Post written by Samuel Han, MD, MS, from The Ohio State University Wexner Medical Center, Columbus, Ohio, USA. In this video, we describe the use of cholangioscopy through a colonoscope to successfully retrieve a stent that had migrated into the duct during ERCP in a patient with surgically altered anatomy (Roux-en-Y hepaticojejunostomy). After attempting conventional methods …
Intraductal suture leading to biliary stone formation and recurrent obstruction and cholangitis: cholangioscopy-guided forceps removal
Post written by Najib Nassani, MD, MSc, from CentraCare Interventional Endoscopy Program, St. Cloud Hospital, St. Cloud, Minnesota, USA. We reported on the case of a 64-year-old woman who had a cholecystectomy several years ago and presented with recurrent choledocholithiasis and cholangitis despite previous ERCPs. Upon balloon sweep during ERCP, a stone attached to the bile …
