ObjectivesThis study aimed to describe the mode of refeeding, frequency of intolerance, and related factors in mild acute pancreatitis (AP).MethodsWe included all cases of mild AP between January 2007 and December 2009 in an observational, descriptive, and retrospective study. We analyzed demographic and etiological data, admission variables, treatment, refeeding mode, intolerance frequency, and treatment. Intolerance-related variables were determined using a Cox regression.ResultsTwo-hundred thirty-two patients were included (median age, 74.3 years, bedside index for severity in AP score, 1). Oral diet was reintroduced at 3 days (range, 0-11 days) in 90.9% of cases with a liquid diet. Intolerance to refeeding appeared in 28 patients (12.1%) at a median time of 1 day (range, 0-14 days). Oral diet was reduced or suspended in 71.4%; analgesic and antiemetic drugs were required in 64% and 35.7% of patients, respectively. The variables independently associated with intolerance to refeeding were choledocholithiasis (hazard ratio [HR], 12.35; 95% confidence interval [CI], 2.98-51.19; P = 0.001), fasting time (HR, 1.33; 95% CI, 1.09-1.63; P = 0.005), refeeding with complete diet (HR, 4.93; 95% CI, 1.66-14.66; P = 0.04), length of symptoms before admission (HR, 1.004; 95% CI, 1.001-1.006; P = 0.012), and metamizole dose (HR, 1.11; 95% CI, 1.02-1.21; P = 0.014).ConclusionsIntolerance to refeeding is an infrequent event. We have identified several factors independently associated with intolerance.
