Through-the-cholangioscope metal biliary stent placement as a novel endoscopic technique for bile duct strictures

The management of biliary strictures remains challenging. Biliary drainage via endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) are the currently preferred approaches [1] [2] [3], but advances in cholangioscopy are allowing new tools to be considered [4]. We present our experience using a novel through-the-cholangioscope self-expandable metal stent (TTC-SEMS; Micro-Tech, Nanjing, China) ([Video 1]).
