Do the morphological features of walled off pancreatic necrosis on endoscopic ultrasound determine the outcome of endoscopic transmural drainage?

摘要

Background and Objective:Endoscopic transmural drainage is an effective, but technically demanding treatment modality for walled off pancreatic necrosis (WOPN). The factors that determine the outcome of endoscopic treatment for WOPN have been infrequently studied. We aim to retrospectively correlate the morphological features of WOPN on endoscopic ultrasound (EUS) with the outcome of endoscopic transmural drainage.
