Safety, diagnostic accuracy and therapeutic efficacy of digital single-operator cholangioscopy.

Background: Digital single-operator cholangioscopes (digital SOCs), equipped with an improved image quality, have been recently introduced.

Objective: The aim of this study is to evaluate the safety and diagnostic and therapeutic efficacy of digital SOCs (Spyglass™ DS).

Methods: Sixty-seven digital SOC procedures performed between 2015 and 2017 were retrospectively analyzed.

Digital single-operator cholangioscopy: a useful tool for selective guidewire placements across complex biliary strictures.

Background: Treatment of biliary strictures is challenging. Digital single-operator cholangioscopes (SOCs) equipped with an improved imaging quality, were recently introduced and may be useful for selective guidewire placement in difficult biliary strictures.

Methods: A total of 167 digital SOC procedures performed between 2015 and 2018 were retrospectively analyzed for successful guidewire placements across biliary strictures.
