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 ...

Peroral-cholangioscopy to plan surgery for protruding biliary lesions: report of four cases

, 2022
Intraductal biliary lesions can involve the main hepatic confluence. Assessment of the extension of pedunculated biliary lesions during per-oral cholangioscopy (POCS) can optimize and personalize the surgical strategy.

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 ...

Structural or functional abnormality of sphincter of Oddi: an important factor for the recurrence of choledocholithiasis after endoscopic treatment

Annals of Medicine
A high recurrence rate is undesirable after treatment of common bile duct (CBD) stones. A major risk factor identified for recurrence is that invasive techniques, including surgical or endoscopic treatments, will impair the biliary tract system either by
