Figure 3: (a) Endoscopic ultrasound showed the dilation of B3 segment due to the recurrence of liver metastasis at the porta hepatis and a SEMS of B2 segment. (b) The B3 segment was punctured under endoscopic ultrasound guidance, and cholangiography showed a dilation of B3. (c) A self-expanding metal stent was placed in the stricture site using stent-in-stent technique
