Successful cholangioscopy-guided cannulation using a novel slim cholangioscope in a patient with Roux-en-Y gastrectomy

Selective biliary cannulation in patients with Roux-en-Y gastrectomy is technically challenging [1] [2]. Peroral cholangioscopy (POCS) is beneficial for direct visualization of intraductal bile duct lesions [3]. Recent studies have confirmed the viability of cholangioscopy-guided cannulation [4]. We report a successful cholangioscopy-guided cannulation achieved using a novel slim cholangioscope in a patient with Roux-en-Y gastrectomy.
