Background and Objectives: Endoscopic ultrasonography (EUS)-guided transluminal drainage for pancreatic fluid collections (PFCs) has become the standard therapy worldwide as a minimally invasive therapy compared with surgical drainage. Recently, a novel flared-type biflanged metal stent (BFMS) designed specifically for the treatment of PFCs has been developed. The aim of this study was to retrospectively assess the feasibility and safety of EUS-guided drainage and direct endoscopic necrosectomy (DEN) for PFCs using the novel flared-type BFMS. Patients and Methods: Twenty-one patients were treated by EUS-guided drainage using a flared-type BFMS for PFCs (pancreatic pseudocyst, 2 patients; walled-off necrosis, 19 patients). Results: The present study showed a technical success rate of 100%, a final clinical success rate of 100%, a procedure-related adverse event (AE) rate of 0%, an early AE rate of 28.6% (moderate and severe AE rate of 9.5%), a mortality rate of 0%, and a recurrence rate of 9.5%. DEN (mean, 2.3 sessions) was required in 38% of the patients. Conclusion: The present study clarified that the EUS-guided drainage using the flared-type BFMS is an effective and safe treatment approach for PFCs. Further studies using randomized controlled multicenter trials are warranted.
