Acute pancreatitis (AP) remains among the most common gastrointestinal disorders leading to hospital admission. Optimizing nutritional support and maintaining gut function is instrumental in recovery of patients with AP. Enteral nutrition remains one of the only interventions with demonstrated mortality benefit in AP largely through preservation of gut function, serving to preserve the gut barrier as means to mitigate immune dysregulation and systemic inflammation inherent to AP. Practice variation remains in timing, route, and composition of nutritional support. This review highlights contemporary evidence regarding optimal nutritional support in AP and provides recommendations for management in line with current consensus opinions.
