Acute Pancreatitis (AP) is a potentially fatal syndrome, associated with a hyper-catabolic state as well as early and late complications that may lead to multi-organ failure and death. Clinical researches produced in recent years suggest that acute pancreatitis may benefit from early oral or enteral nutrition. Nevertheless, many clinicians still believe erroneously that fasting – particularly in the early phase – may reduce AP complications and mortality. The goal of our review is to demonstrate that such false belief may harm the patients and that the whole management paradigm must change, adopting a more rational, evidence-based approach. First, we will describe AP physiopathology and the clinical assessment of its severity. Then we will discuss evidence-based data supporting early oral or enteral nutrition in AP. Finally, we will offer some practice recommendations as regards nutritional support.
