Association between probiotics and enteral nutrition in an experimental acute pancreatitis model in rats.

Background/objectives: Recently, a randomized controlled trial showed that probiotic prophylaxis was associated with an increased mortality in enterally fed patients with predicted severe pancreatitis. In a rat model for acute pancreatitis, we investigated whether an association between probiotic prophylaxis and enteral nutrition contributed to the higher mortality rate.

Methods: Male Sprague-Dawley rats were allocated to four groups: 1) acute pancreatitis (n = 9), 2) acute pancreatitis and probiotic prophylaxis (n = 10), 3) acute pancreatitis and enteral nutrition (n = 10), and 4) acute pancreatitis, probiotic prophylaxis and enteral nutrition (n = 11).
