Figure 2 Fully covered biliary stents were placed after evaluation by magnetic resonance cholangiopancreatography and cholangiography (step 1). A: Magnetic resonance cholangiopancreatography before fully covered stent placement. The orange arrow indicates the impacted stone; B: Cholangiography before fully covered stent placement. The orange arrow indicates the impacted stone; C: Fully covered stent placement; D: Cholangiography after fully covered stent placement. The patient previously underwent biliary stent placement (7 Fr × 7 cm).
