Prospective Clinical Evaluation of a Novel Repositionable Plastic Stent for Endosonography‐Guided Hepaticogastrostomy With or Without Antegrade Stenting (With Videos)

Journal of Gastroenterology and Hepatology, Volume 41, Issue 9, Page 2817-2825, September 2026.
ABSTRACT Background and study aims A repositionable plastic stent (PS), developed to overcome the limitations of conventional pusher‐type PS in endosonography‐guided hepaticogastrostomy (EUS‐HGS), minimizes the gap between the inner sheath and stent to improve insertability.

Feasibility of Comprehensive Genomic Profiling for Biliary Tract Cancer Using Transpapillary Biopsy Samples: A Prospective Study

Journal of Hepato-Biliary-Pancreatic Sciences, Volume 33, Issue 8, Page 615-623, August 2026.
Miyamoto and colleagues found that introducer‐assisted multipass transpapillary biopsy could yield specimens suitable for comprehensive genomic profiling in biliary tract cancer, although suitability remained limited and panel dependent. Fresh frozen samples yielded markedly higher DNA quality than formalin‐fixed paraffin‐embedded samples, supporting ...

Endoscopic findings of gallbladder lesions evaluated with image‐enhanced endoscopy: A preliminary study using resected gallbladders

DEN Open, Volume 6, Issue 1, April 2026.
Abstract The diagnosis of gallbladder (GB) lesions relies on imaging findings. Transpapillary cholangioscopy can potentially be used to diagnose GB lesions; however, the images obtained remain unclear. This study aimed to characterize the endoscopic findings of GB lesions. We examined the endoscopic features of GB lesions in 50 consecutive patients who

A Case of Obstructive Jaundice due to Bile Duct Tumor Thrombus of Hepatocellular Carcinoma Diagnosed by Peroral Cholangioscopy

DEN Open, Volume 6, Issue 1, April 2026.
Abstract While hepatocellular carcinoma (HCC) often invades the portal or hepatic vein to form tumor thrombus, tumor thrombus in the bile duct is rare. In such cases, differentiation from intrahepatic cholangiocarcinoma is difficult, and the tumor often appears as a smooth, yellowish‐white, polypoid mass within the bile duct lumen.
