Association between morphological features of necrotizing pancreatitis on endoscopic ultrasound and outcomes of the endoscopic transmural step-up approach.

More solid necrotic debris on EUS is related to more necrosectomy sessions, higher incidence of stent occlusion and longer hospitalization. A nomogram combining procalcitonin and any organ failure performs well in predicting clinical failure of endoscopic transmural step-up approach.
