New Options of Cholangioscopy [PDF]

Gastroenterology Clinics of North America, 2010
In the evaluation of biliary diseases, cholangioscopy is considered as complementary procedure to radiographic imaging. Direct visualization of the bile duct is the premier advantage of cholangioscopy over indirect imaging techniques. However, cholangioscopy has not gained wide acceptance because of several technical limitations such as scope fragility,

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 ...

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.

Cholangioscopy and pancreatoscopy (with videos)

Gastrointestinal Endoscopy, 2009
Because the pancreatobiliary tract is not readily accessible to direct visualization by endoscopy, the tract remains a formidable challenge when it comes to differentiate benign from malignant pathologies. Thus, the evaluation of pancreatobiliary disease has relied on radiographic imaging by CT scan, magnetic resonance imaging, MRCP, ERCP, and EUS ...

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.

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.

Cholangioscopy and pancreatoscopy

Techniques in Gastrointestinal Endoscopy, 2017
Abstract Cholangiopancreatoscopy has evolved significantly since its introduction over 40 years ago. The systems have gone through multiple iterations that has allowed for widespread performance of per-oral cholangiopancreatoscopy for diagnostic and therapeutic intent.

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 ...

Direct cholangioscopy and pancreatoscopy

Gastrointestinal Endoscopy Clinics of North America, 2003
Direct cholangiopancreatoscopy has played a minor role in the diagnosis and treatment of pancreaticobiliary disorders, initially because of instrument fragility and suboptimal imaging, and later because of improvements in noninvasive and semi-invasive imaging techniques.
