Predictors of the need for necrosectomy in patients with walled-off pancreatic necrosis treated with lumen apposition metal stents.

Background And Aims: Endoscopic necrosectomy through lumen apposition metal stents (LAMS) is increasingly being used for complicated walled-off pancreatic necrosis (WOPN), but the need for necrosectomy after stent placement is not well understood. The aim of this study was to evaluate clinical, endoscopic, and radiologic predictors of the need for necrosectomy in patients treated with LAMS.

Methods: We retrospectively reviewed patients with WOPN treated with LAMS from 2014 to 2017.
