Finkelmeier F, et al. - This study was set up with the aim to identify imaging parameters and clinical findings predicting the need of necrosectomy in patients with walled-off necrosis (WON). When needed to predict treatment of patients with pancreatic cysts, computed tomography scans were of low diagnostic yield. While patients with diabetes appeared to be at higher risk of developing WON, reduced pancreatic perfusion and solid findings seemed to be a risk factor for WON.
