[Cholangioscopy].

Der Internist, 2013
Cholangioscopy is an important component of the management of a selected group of patients with biliary diseases. Due to the advantage of direct visualization cholangioscopy provides targeted diagnostic and therapeutic procedures under endoscopic control.

Percutaneous Transhepatic Cholangioscopy Interventions—Updates

Journal of Clinical Gastroenterology, 2023
Percutaneous transhepatic cholangioscopy (PTCS) was initially described around the same time that peroral cholangioscopy (POSC) was developed. The cited utility attributed to PTCS is the ability to be utilized in the subset of patients with surgical ...

Virtual CT Cholangioscopy: Comparison with Fiberoptic Cholangioscopy

Endoscopy, 2001
No studies comparing virtual computed tomography (CT) cholangioscopy of the common bile duct compared with fiberoptic cholangioscopy are available. The aim of our study was to evaluate the feasibility of virtual CT cholangioscopy of the common bile duct.The study population comprised 52 patients (25 women, 27 men; mean age 56.5, range 32 - 81) with ...

Fine Caliber Cholangioscopy

Radiologic Clinics of North America, 1990
The miniaturized diameters of endoscopes (miniendoscopes) allow percutaneous access for endoscopic visualization of the extrahepatic and intrahepatic biliary system. Practical aspects of different miniendoscopes in an experimental model are described.

A comparative study of extracorporeal shock wave lithotripsy and cholangioscopy-guided lithotripsy in the management of complex biliary stones: A randomized trial.

Journal of Trauma and Acute Care Surgery
BACKGROUND Large and impacted common bile duct stones (CBDSs) cannot be removed by conventional endoscopic retrograde cholangiopancreatography (ERCP), and extracorporeal shock wave lithotripsy (ESWL) or cholangioscopy-guided lithotripsy is recommended as

Multicenter validation of a cholangioscopy artificial intelligence system for the evaluation of biliary tract disease

Endoscopy
Background Clinicians struggle to accurately classify biliary strictures as benign or malignant. Current endoscopic retrograde cholangiopancreatography (ERCP)-based sampling modalities including brush cytology and forceps biopsy have poor sensitivity for

Choledochoscopy/Cholangioscopy

Gastrointestinal Endoscopy Clinics of North America, 2013
Miniature endoscopes that can be introduced into the bile duct through the duodenoscope during endoscopic retrograde cholangiopancreatography were developed to allow nonsurgical management of difficult biliary stones. The direct visualization enabled by these cholangioscopes of the biliary epithelium provides additional data in the assessment of ...

Percutaneous Transhepatic Cholangioscopy

Techniques in Vascular and Interventional Radiology, 2015
The role of the interventional radiologist continues to expand in the treatment of biliary disease. Percutaneous transhepatic cholangioscopy (PTCS) provides direct visualization of the biliary system for diagnostic and therapeutic interventions, especially in cases where anatomical considerations prohibit a peroral approach.

Acceptable number of cholangioscopy-guided biopsies for diagnosing perihilar cholangiocarcinoma.

Revista Espanola de Enfermedades Digestivas
INTRODUCTION Diagnosing perihilar cholangiocarcinoma can be challenging. Previous studies suggest that the sensitivity of taking three cholangioscopy-guided biopsies is approximately 70%. We hypothesized that obtaining four or more biopsies might improve

Indications for Cholangioscopy

Endoscopy, 1989
Cholangioscopy permits new diagnostic and therapeutic procedures. It can be performed via the peroral route when anatomical conditions are suitable. This procedure was attempted in 6 cases (lithiasis in 5, malignant stenosis in 1): cholangioscopy proved possible in 4 cases, and lithotripsy was successful in 2 cases out of 3.
