However, stent migration is a well\u2010known complication. We report a rare case of small\u2010bowel impaction caused by the migration of a duodenal SEMS with a biliary plastic stent (PS). A 78\u2010year\u2010old woman with pancreatic head cancer underwent biliary PS and duodenal SEMS placement for obstructive jaundice and GOO. At 4 months after initiating neoadjuvant chemotherapy, computed tomography revealed tumor shrinkage and improvement in duodenal stenosis; however, the SEMS and PS had migrated to the ileum. Double\u2010balloon enteroscopy was attempted; however, stent removal was unsuccessful because of mechanical interlocking and impaction. Therefore, a partial ileal resection was performed. Histopathological examination revealed transmural infiltration of inflammatory cells and abscess formation. If a duodenal SEMS migrates with a biliary PS, mechanical interlocking may occur, resulting in small\u2010bowel impaction. Clinicians should be aware of this rare complication and should consider careful follow\u2010up and timely intervention if stent migration is detected.<\/jats:p>\n                  <jats:p>\n
