Endoscopic retrieval of proximally migrated biliary and pancreatic stents: experience of a large referral center

A review of problems following insertion of biliary stents illustrated by an unusual complication

“…20,[27][28][29] Price et al 30 reported a successful retrieval rate of 78% which is consistent with results from other retrospective studies that showed a retrieval rate of 80% and 75% for main and dorsal pancreatic duct stents, respectively. 31 The migration of self-expandable metal stents occurs rarely, with a frequency of less than 1%, because the surrounding tissue grows through the interstices of the stent and produces fixation, although the same process is believed to lead to occlusion eventually. [32][33][34][35] It is also believed that the shortening that occurs following placement aids security.…”

Successful management of recurrent biliary colic caused by pancreatic stent migration after Whipple procedure

“…Other invasive therapeutic options such as surgery or percutaneous approaches are used for removal of a migrated pancreatic stent in patients who fail ERCP. 16 …”

A Potentially Fatal Complication of Biliary Stent Migration

“…A recent review showed that this might be difficult for proximally migrated stents (71.4% success) but was more successful for distally migrated stents (100% successfully retrieved) [4]. Indeed 80-86% success for proximal stent retrieval has also been reported but it is a technical challenge to the endoscopist [5]. A strategy of permitting spontaneous extrusion of a planned temporary stent from the bowel may also be followed.…”
