Aim: The aim of this study was to investigate the incidence, risk factors, and treatment strategies of proximally migrated pancreatic stents. Materials and Methods: The data of 626 sessions of 421 patients with pancreatic duct stenting were retrospectively analyzed between 2010 and 2018, and patients with proximally migrated stents were included in the study. Results: Of 626 stents examined, 77 migrated proximally (12%). The migration rate (MR) was 16%, 2%, and 7%, respectively, in patients treated with chronic pancreatitis, malignancy, and pancreatic leakage indication. The MR was 14% in procedures with pancreatic duct stenosis, 21% in procedures with pancreatic sphincterotomy, and 27% in procedures performed from minor papillae. The MR of the 5, 7, and 10 Fr stents was 4%, 17%, and 10%, respectively. Of the 77 migrated stents, 64 were successfully removed (83%). This success rate (SR) was 84% in procedures with chronic pancreatitis indication, 83% in procedures with pancreatic duct stenosis, 79% in procedures with sphincterotomy, and 75% in procedures performed from minor papillae. The SR of the 5, 7, and 10 Fr stents was 100%, 79%, and 92%, respectively. It was also determined that 33 stents were fractured and migrated (43%). The SR of the fractured stents was 76%. Moreover, of the stents that were successfully removed, 35 were removed with forceps (55%) and 15 (23%) were removed with a balloon. Furthermore, in 47 cases, the stent was removed in the first session (73%). Acute pancreatitis occurred in 5 patients (8%) and perforation occurred in 1 patient (2%). Conclusion: In this study, it was shown that proximal migration of pancreatic stents is frequent and most of these stents can be removed successfully.
