Abstract
ObjectiveTo explore the reasons of the proximal migration of pancreatic stents and the endoscopic management.
MethodsFrom April 2007 to January 2015, of all 967 patients with biliopancreatic diseases implanted with pancreatic duct plastic stents at the First Affiliated Hospital of Nanchang University, proximal migration occurred in 10 cases. Migrated rates and endoscopic retrieval methods of pancreatic straight stents and single pigtail stents were compared.
ResultsPancreatic straight stents showed a higher migration rate than those single pigtail ones [3.23% (7/217) VS 0.40% (3/750)]. For 3 migrated single pigtail pancreatic stents: 2 were directly removed with biopsy forceps. Another failed in retrieval, and the same stent then was implanted. There was no discomfort after the operation. For 7 migrated pancreatic straight stents: 2 were pulled out of duodenum papilla incision under wire-guided balloon and basket. Five others were pulled out of papilla under wire-guided balloon, and then the stents were removed by a snare.
ConclusionPancreatic straight stents are more likely to migrate compared with single pigtail stents. Migrated pancreatic straight stents can be removed with wire-guided balloon or basket and snare, while migrated single pigtail stents can be directly retrieved with biopsy forceps.
