Migrated Pancreaticojejunal Stent Forming a Stent–Stone Complex in the Jejunum with Resultant Small Bowel Obstruction: A Case Report

Transanastomotic pancreatic duct stent placement during reconstruction following pancreaticoduodenectomy is widely performed to prevent postoperative pancreatic fistulas and duct stenosis. However, stent-related complications, such as stent occlusion and migration, may occur. Here, we report a rare case of a migrated pancreatic duct plastic stent. After pylorus-preserving pancreaticoduodenectomy, the stent migrated to the jejunum and served as a nidus of the stent–stone complex, which developed jejunal obstruction. The stent–stone complex was removed by explorative laparotomy.
