Background Walled-off pancreatic necrosis (WOPN) is effectively managed with percutaneous and endoscopic techniques such as direct endoscopic necrosectomy. However, they require repeat interventions and lengthy hospital stays. Objective To evaluate a new platform to manage WOPNs by using a large-bore, through-the-scope, fully covered, self-expandable metal stent (FCSEMS) to overcome the need for repeat interventions and extended hospital stays. Design Retrospective, single-center study. Setting Academic tertiary care center. Patients Five consecutive patients with symptomatic WOPN underwent EUS-guided drainage of WOPN by using a large-bore FCSEMSs. Interventions EUS-guided transgastric drainage of WOPN by using a large-bore FCSEMS. Cross-sectional imaging was repeated at 6- to 8-week intervals. The FCSEMS was removed after WOPN resolution. Main Outcome Measurements Clinical success, number of repeat interventions, and length of hospital stay. Results Five patients (mean age 60 years) with WOPN (mean diameter, 12.3 cm; range 9.8-14.3 cm) underwent drainage with the described technique. Technical and clinical success was achieved in 100% of patients. Direct endoscopic necrosectomy was not required in any patient. The median number of endoscopic procedures was 1. The median length of hospital stay was 1 day. There were no adverse events. Limitations Small, retrospective study. Conclusions The described novel platform facilitates resolution of WOPN with a single procedure, avoiding the need for repeat interventions and lengthy hospital stays.
