Necrosectomy and its timing in relation to clinical outcomes of endoscopic ultrasound-guided treatment of walled-off pancreatic necrosis: a multicenter study

Endoscopic ultrasound (EUS)-guided transmural drainage with on-demand endoscopic necrosectomy (EN) is increasingly utilized to manage walled-off necrosis (WON). It has not been fully elucidated how EN and its timing are correlated with treatment outcomes compared to the drainage-based approach.
