Vendor‐Agnostic Vision Transformer‐Based Artificial Intelligence for Peroral Cholangioscopy: Diagnostic Performance in Biliary Strictures Compared With Convolutional Neural Networks and Endoscopists

Digestive Endoscopy, Volume 37, Issue 12, Page 1315-1322, December 2025.
ABSTRACT Objectives Accurate diagnosis of biliary strictures remains challenging. This study aimed to develop an artificial intelligence (AI) system for peroral cholangioscopy (POCS) using a Vision Transformer (ViT) architecture and to evaluate its performance compared to different vendor devices, conventional convolutional neural networks (CNNs), and ...

Validity and safety of endoscopic biliary stenting for biliary stricture associated with IgG4-related pancreatobiliary disease during steroid therapy

Endoscopy International Open, 2019
Background Patients with IgG4-related sclerosing cholangitis and autoimmune pancreatitis frequently develop obstructive jaundice, which requires endoscopic biliary stenting (EBS) during steroid therapy to prevent bile duct infection from cholestasis and ...

Diagnostic Utility of Liver Biopsy in Persistent Unexplained Liver Enzyme Elevation: A Retrospective Cohort Study

JGH Open, Volume 9, Issue 11, November 2025.
ABSTRACT Background and Aims Chronically elevated liver enzymes without a clear etiology remain a frequent diagnostic challenge. This study evaluated the diagnostic yield of liver biopsy in such cases and assessed if laboratory parameters predict histological clarification. Methods We retrospectively analyzed 71 patients with unexplained elevated liver

Tepotinib‐Induced Cholangitis in a Patient With Non‐Small Cell Lung Cancer: A Case Report

Respirology Case Reports, Volume 13, Issue 11, November 2025.
Here, we report the first case of tepotinib‐induced cholangitis. When using MET inhibitors for chemotherapy, attention should be paid not only to treatment effectiveness but also to possible hepatobiliary side effects. ABSTRACT Tepotinib, a mesenchymal epithelial transition factor (MET) tyrosine kinase inhibitor, is used to treat non‐small cell lung ...

European Consensus Recommendations for Direct Cholangioscopy and Pancreatoscopy Using a Modified Delphi Process

United European Gastroenterology Journal, Volume 13, Issue 9, Page 1652-1667, November 2025.
ABSTRACT Background and Aim Direct cholangioscopy and pancreatoscopy have become widely implemented techniques in the diagnostic and therapeutic algorithms of several pancreaticobiliary disorders. This study aimed to generate general and indication‐specific European consensus recommendations on cholangioscopy and pancreatoscopy.
