Complications and expected imaging findings after endoscopic retrograde cholangiopancreatography

Figure 16  Proximal stent migration. A and B: Axial (A) and sagittal (B) contrast-enhanced computed tomography of a 73-year-old male patient with a history of biliary stenting. He presented with persistent abdominal pain following revision of the common bile duct stent 1 week prior. The patient developed progressive jaundice, pruritus, and recurrent fever. Laboratory tests revealed elevated levels of bilirubin, aspartate aminotransferase, and alanine aminotransferase. The stent, which should be located within the common bile duct, migrated proximally into an intrahepatic bile duct and extended toward the subcapsular region of hepatic segment IV (yellow arrows).
