Background: Recently, the introduction of the novel digital SpyGlass™ DS Direct Visualization system (Boston Scientific Corp., Natick, MA, USA) has signaled the transition into the era of digital single-operator cholangioscopy (D-SOC). We sought to compare the clinical utility between fiberoptic single-operator cholangioscopy (F-SOC) and D-SOC in a tertiary-care referral center in Greece.

Methods: This was a retrospective analysis of a prospective database of single-operator cholangioscopy (SOC) procedures performed over an 8-year period (2009-2017) at a single tertiary-care referral center. The study population consisted of consecutive adults referred for cholangioscopy for a variety of clinical indications, including biliary strictures, difficult biliary stones and migrated or occluded pancreatic or biliary stents.

Results: A total of 2763 endoscopic retrograde cholangiopancreatography procedures were performed during the study period. Overall, SOC was performed in 68 (2.46%) procedures (F-SOC=39, D-SOC=29), showing a significant increase in the utilization of cholangioscopy during the D-SOC (29/599; 4.84%) compared with the F-SOC (39/2124; 1.83%) period (P=0.0001). The overall technical success of diagnostic SOC was 69.1% (38/55), being marginally higher for D-SOC (83.3%) than for F-SOC (58.1%), although not reaching statistical significance (P=0.07).

Conclusions: D-SOC was utilized more frequently in our tertiary-care non-academic referral center, demonstrating a favorable safety profile and a trend towards a marginally higher technical success rate for the diagnosis of biliary strictures compared with F-SOC.
