Postoperative acute necrotizing pancreatitis of the pancreatic remnant (POANP): a new definition of severe pancreatitis following pancreaticoduodenectomy.

Patients requiring CP following PD for POANP have an increased risk of major complications, and longer hospital stay. CRP levels, APACHE II and SOFA score, seem to correlate with the severity and might predict POANP. Universally accepted definitions with a clinically validated grading system of severity for POAP and POANP are needed to facilitate appropriate treatment strategies and enable comparison of future studies.
