We aimed to review our catheter-based cholangioscopy interventions in patients with indeterminate biliary stenosis, using the SpyGlass Direct Visualization System (SDVS) and summarize our experience in terms of procedures and results.

We aimed to review our catheter-based cholangioscopy interventions in patients with indeterminate biliary stenosis, using the SpyGlass Direct Visualization System (SDVS) and summarize our experience in terms of procedures and results.


 Sensitivity, specificity and accuracy for visual diagnosis by SDVS in our cohort were 100, 83.3 and 96 %, respectively.  Today, the SDVS should be considered essential in diagnosing indeterminate biliary strictures, since the procedure is associated with high procedural success in terms of diagnostic accuracy, alters clinical outcome in over 80 % of considered insolvable cases, with an acceptable safety profile.
