Endoscopic retrograde cholangiopancreatography (ERCP) is the gold‐standard modality for diagnosis and therapy of bilio‐pancreatic disease. In particular, peroral cholangiography (POCS) is a useful modality not only for diagnosing biliary disease, but also for therapeutic procedures such as electrohydraulic lithotripsy. The SPY‐DS single‐operator cholangioscope has recently become available, and offers favorable visualization, a wide view, suction function and a larger accessory working channel. However, if the duodenoscope cannot be advanced into the ampulla of Vater for reasons such as surgical anatomy, POCS cannot be performed. On the other hand, percutaneous transhepatic cholangiodrainage (PTCD) has been developed as an alternative endoscopic ultrasound‐guided approach to the biliary tract. Peroral transluminal cholangioscopy (PTLC) using SPY‐DS is a novel approach. Because transluminal interventional procedures under endoscopic ultrasound guidance have recently been developed, our technique may have clinical impact for selected cases.
