The Effect of Dietary Fat Content on the Recurrence of Pancreatitis

Around 20% of patients with acute pancreatitis (AP) will go on to have acute recurrent pancreatitis (ARP) and 10% progress to chronic pancreatitis (CP). While interventions to avoid recurrences exist for the two most common causes - removal of the cholecyst in the case of biliary, and alcohol seccation in the case of alcoholic - a method to prevent idiopathic pancreatitis is not yet known. Although none of the guidelines suggest the administration of low fat diet, it is recommended by physicians to all pancreatitis patients are. Our aim is to conduct a randomized controlled trial, to assess the problem of dietary fat reduction on the recurrence of acute pancreatitis Patients, who had at least two acute pancreatitis episodes in the preceding 2 year will be approached to participate in the study and to either to be randomized to the 'reduced fat diet' (15% fat, 65% carbohydrate, 20% protein) or to the 'standard healthy diet' (30% fat, 50% carbohydrate, 20% protein; based on WHO recommendations) group. During the 2 year long followup, participants will receive repeated dietary intervention at 3, 6, 12, 18, 24 months, they will completer food frequency questionnaires and their data regarding mortality, BMI, cardiovascular parameters and serum lipid values will be recorded The EFFORT trial will determine the effect of modified dietary fat content on the recurrence of AP, mortality, serum lipids and weight loss in idiopathic cases.
