Although the idea that pancreas rest has long been considered as a very relevant topic in acute pancreatitis (AP) therapy, the right time and type of diet to be offered to patients recovering from an acute attack are a great challenge to clinicians who treat this condition. Fortunately, the last decade was noted for several trials looking for the best answer to the question: “when and how to start oral refeeding in AP?” It is well known that 80% of patients present with mild disease characterized by usually uncomplicated clinical course are managed with pancreatic rest through nil per oral; while the use of specific nutritional intervention is an exception. Therefore, mild AP has been the most investigated form of AP and researchers have tried different kind of meals to offer calories and reduce costs by shortening hospitalization time. Usually in mild AP, the oral refeeding is introduced between the first 3 d and 7 d after hospitalization but, the type of diet and patients’ tolerance have been scrutinized in detail with mixed results. Although 20% to 25% have pain recurrence requiring nutritional support and greater time of hospitalization, most patients seem to tolerate oral refeeding well. We propose analyzing the most recent investigations of this matter and their conclusions to develop a better understanding of the management of AP.
