Objectives: To report the safety and clinical efficacy with the novel lumen-apposing metal stent (LAMS) with an electrocautery enhanced delivery system for the drainage of pancreatic fluid collections (PFCs). Methods: This was a retrospective analysis of all consecutive patients with PFCs who underwent endoscopic ultrasound (EUS)-guided drainage using the LAMS with an electrocautery enhanced delivery system in 2 US centers. Results: Thirteen patients with PFCs (69% with walled-off necrosis [WON]) underwent drainage using the study device. Successful stent placement was accomplished in all patients. Direct endoscopic necrosectomy was carried out in all nine patients with WON complete resolution of the PFC was obtained in all 13 cases, with no recurrence during follow-up. There was one procedure-related adverse event. In one patient, the LAMS was dislodged immediately after deployment, falling into the stomach where it was removed. A second electrocautery enhanced LAMS was placed in this patient immediately afterward. Conclusions: EUS-guided drainage using the LAMS with the electrocautery-enhanced delivery system is a safe, easily performed, and a highly effective for the drainage of PFCs.
