Background and Objectives: Long-term indwelling transmural stents in patients with walled off pancreatic necrosis (WOPN) and disconnected pancreatic duct syndrome (DPDS) decreases risk of recurrence of pancreatic fluid collection (PFC). However, stents can spontaneously migrate causing recurrence of PFC in some patients whereas some patients may have asymptomatic migration of stents. We aim to retrospectively evaluate profile of patients with recurrent PFC following migration of transmural stents in patients with WOPN and DPDS and compare it with patients who had asymptomatic migration of stents. Patients and Methods: Records of consecutive patients who underwent endoscopic transmural drainage of WOPN over last 4 years were analyzed and patients with DPDS identified. Results: Thirty-five patients (29 M; mean age 37.0 ± 7.6 years) were followed-up for mean of 28.2 ± 14.0 months (range: 6-50 months). Eight patients (22.8%) had spontaneous migration of stents. It led to recurrence of PFC in three patients, whereas in five patients it was asymptomatic. The patients with recurrent PFC had early stent migration (2, 4, and 5 months respectively) whereas patients with asymptomatic migration had their stents migrating >6 months of resolution. Patients with recurrent PFC had duct disruption in pancreatic head (100% vs. 20%), and low frequency of diabetes (nil vs. 40%), steatorrhea (nil vs. 20%) as well as pancreatic atrophy (nil vs. 80%). Conclusion: Early migration of stents, ductal disruption in pancreatic head as well as absence of diabetes, steatorrhea, and pancreatic atrophy seem to increase risk of recurrent PFC following migration of transmural stents in patients with DPDS.
