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 ...

The Usefulness of Percutaneous Transhepatic Cholangioscopy for Identifying Malignancies in Distal Commom Bile Duct Strictures [PDF]

, 2008
The diagnostic accuracy of percutaneous transhepatic cholangioscopy (PTCS) was compared to that of three radiologic modalities in distal common bile duct (CBD) strictures for the evaluation of clinical application. Ninety-five patients who underwent PTCS

Evaluating the yield of digital single operator cholangioscopy in posttransplant biliary strictures after unsuccessful guidewire placement with ERCP

JGH Open
Background and Aims Strictures are the most common biliary complication after liver transplantation, and endoscopic retrograde cholangiopancreatography (ERCP) is considered the gold standard in its management.

Lymph Node Metastasis Around the Common Hepatic Artery Is Associated With Dismal Prognosis in Patients Undergoing Resection of Extrahepatic Cholangiocarcinoma

Journal of Hepato-Biliary-Pancreatic Sciences, Volume 32, Issue 10, Page 756-765, October 2025.
Kiritani and colleagues identified lymph node metastasis around the common hepatic artery as a powerful independent predictor of poor survival in extrahepatic cholangiocarcinoma. Readily detectable on imaging and accessible during surgery, common hepatic artery node status provides a practical biomarker to refine biological resectability and guide ...
