Endoscopic ultrasonography-guided transmural drainage of walled-off pancreatic necrosis: Comparison between a specially designed fully covered bi-flanged metal stent and multiple plastic stents
Endoscopic ultrasonography (EUS)-guided drainage of walled-off necrosis (WON) may be carried out by placement of multiple plastic stents (MPS) or specially designed fully covered bi-flanged metal stents (BFMS). Comparative data on efficacy of these two stent types for WON drainage are limited. This retrospective study compares outcomes of WON drainage using BFMS and MPS.
