Peroral Cholangioscopy-Guided Targeted Biopsy versus Conventional Endoscopic Transpapillary Forceps Biopsy for Biliary Stricture with Suspected Bile Duct Cancer

Journal of Clinical Medicine, 2022
Background: The recent improvement of peroral cholangioscopy (POCS) maneuverability has enabled the precise, targeted biopsy of bile duct lesions under direct cholangioscopic vision.

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

Role of Peroral Cholangioscopy in the Diagnosis of Primary Sclerosing Cholangitis

Diagnostics, 2020
Primary sclerosing cholangitis (PSC) is characterized by idiopathic biliary stricture followed by progressive cholestasis and fibrosis. When diagnosing PSC, its differentiation from other types of sclerosing cholangitis and cholangiocarcinoma is ...

Usefulness of texture and color enhancement imaging in peroral cholangioscopy

Endoscopy, 2022
The application of peroral cholangioscopy (POCS) has been reported to be useful for detailed inspection of patients with biliary stricture [1, 2]. We report a case of biliary stricture that had undergone POCS using texture and color enhancement imaging ...
