Three pancreatic duct lesions in one patient found at an early stage by cholangioscopy.

A 49-year-old woman with a common bile duct (CBD) stone underwent preoperative magnetic resonance cholangiopancreatography (MRCP) at our hospital. This showed cholangiectasis, the CBD stone, and filling defects in the proximal and middle pancreatic duct (PD) ([Fig. 1]). Endoscopic retrograde cholangiopancreatography (ERCP) was performed, therefore, and the CBD stone was removed successfully; subsequently, the PD was intubated and the filling defect in the mid-PD was confirmed by pancreatography.
