Early Enteral Nutrition is Related to Decreased In-hospital Mortality and Hospitalization in Patients with Acute Pancreatitis: Data from the Japanese Diagnosis Procedure Combination Database

Abstract

Management of early nutrition plays an important role in the treatment of acute pancreatitis patients, but the sample sizes of randomized control trials that have compared enteral and parental nutrition were small. From the data of Diagnostic Procedure Combination, we identified patients who had been diagnosed with acute pancreatitis and discharged from the hospital between 2014 and 2015. We compared the length of hospital stay and hospital mortality among patients with acute pancreatitis that was managed with and without enteral nutrition within 7 days from hospitalization. The results showed a significant decrease in the in-hospital mortality rate of 56% (odds ratio 0.444, 95% confidence interval [CI] 0.358 − 0.551, P < 0.001) and length of hospital stay by 8.6 days (95% CI -9.05 − -8.13, P < 0.001) when enteral nutrition was administered within 7 days. According to multivariate analysis, early enteral nutrition was independently associated with in-hospital mortality rate and length of hospitalization. Enteral nutrition is an important management method for the treatment of acute pancreatitis patients.
