Single-operator Digital Cholangioscopy for the Diagnosis of Malignant and Benign Biliary Strictures

SpyGlass DS Cholangioscopy includes a 10 French diameter single use digital cholangioscope and a light source with the digital sensor. During ERCP with cholangioscopic exam, the cholangioscope would be first inserted through the working channel of the duodenoscope and subsequently passed into the bile duct for direct visualization of the bile duct mucosa. The visual impression (VI) of the biliary stricture will be assessed. Tissue acquisition of the biliary stricture will be performed by cholangioscopy directed biopsy (CDBx), and conventional brush cytology with or without intraductal biopsy.
