walled-off pancreatic necrosis (WOPN) is one of the complications of acute pancreatitis (AP) with high mortality. A method to predict the development of WOPN in AP patients admitted to the emergency department may guide life-saving practices such as early initiation of antibiotic therapy and, when necessary, referral of the patient to a center where necrosectomy can be performed. This study is a prospective observational study. ⋯ In the receiver operating characteristic analysis, all methods except SII were found to be successful in predicting WOPN. QT dispersion, SII, MII-1, MII-2, and MII-3 are valuable tools that provide rapid results and successfully predict the development of WOPN in AP. However, MII-2 and QT dispersion appears to be slightly more successful than the others.
