Complications and expected imaging findings after endoscopic retrograde cholangiopancreatography

Figure 17  Distal stent migration. A: A 56-year-old male patient with a history of endoscopic retrograde cholangiopancreatography (ERCP) and biliary stenting presented with right lower quadrant pain lasting for 3 days. The coronal noncontrast computed tomography (CT) images demonstrated distal migration of the stent into the cecum (orange arrow); B: An 85-year-old patient with a history of ERCP and biliary stenting presented with jaundice. The previous stent was not visualized during ERCP for stent revision, and re-stenting was performed (yellow arrow). Post-procedural coronal contrast-enhanced CT revealed distal migration of the previous stent into the ascending colon (blue arrow).
