IgG4-related sclerosing cholangitis mimicking hilar cholangiocarcinoma (Klatskin tumor): a case report of a challenging disease and review of the literature

Innovative Surgical Sciences, 2018
Even though IgG4-related disease has gained increased attention worldwide, the diagnosis remains challenging. IgG4-related sclerosing cholangitis (IgG4-SC) is not well described in the western hemisphere and may mimic cholangiocarcinoma (CC), especially ...

Distal Bile Duct Metastasis From Rectal Cancer: The Diagnostic Contribution of Intraductal Ultrasonography

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT A 49‐year‐old male developed liver dysfunction during chemotherapy for rectal cancer located in the rectosigmoid region. Although magnetic resonance cholangiopancreatography initially indicated sclerosing cholangitis, endoscopic retrograde cholangiopancreatography and intraductal ultrasonography revealed multiple non‐contiguous intraductal ...

Advances in Diagnosis and Treatment With Cholangiopancreatoscopy

Digestive Endoscopy, Volume 38, Issue 4, April 2026.
ABSTRACT Endoscopic retrograde cholangiopancreatography (ERCP) remains the standard for diagnosing and treating pancreatobiliary diseases. Although non‐invasive imaging modalities have significantly improved, ERCP continues to play an indispensable role in clinical practice. However, ERCP has inherent limitations. Diagnostic challenges persist in cases

A young patient with biliary and urinary disease: What's the unifying diagnosis?

Hong Kong Journal of Emergency Medicine, Volume 32, Issue 6, December 2025.
Abstract Introduction Chronic ketamine abuse is a growing public health concern associated with severe organ damage. While ketamine‐induced uropathy and cholangiopathy are well‐documented complications individually, their simultaneous presentation is rare. This dual‐system involvement, however, provides a key diagnostic clue on imaging.

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 ...
