Abstract
OBJECTIVES: To investigate the possible associations of muscle and visceral fat mass with the prognosis of patients hospitalized with acute pancreatitis. METHODS: Body composition analysis (Sliceomatic, TomoVision, Montreal, Canada) was performed on CT images at the L3 level in patients admitted with acute pancreatitis during 2008-2014. Regression analysis was used to examine associations of body composition with 1-year mortality and 1-year readmission rates. RESULTS: A total of 158 patients were included (mean age 63.7 ± 17.4 years, 91 (57.6%) were male). Fat was the most abundant tissue (408 ± 180 cm2 surface area). None of the prognostic factors examined were associated with 1-year mortality. Values below compared to above the medians for muscle mass and visceral fat were associated with higher mean 1-year readmissions: 1.7 versus 1.0, p = 0.02 and 1.6 versus 1.1, p = 0.09, respectively. Logistic regression analysis showed an association of high visceral fat with reduced 1-year readmission (OR 0.995, 95% CI 0.991-1.000, p = 0.03). Linear regression analysis showed an inverse correlation of visceral fat mass with the number of 1-year readmissions (HR -0.004, 95% CI -0.008-000, p = 0.070). CONCLUSIONS: Higher amounts of visceral fat and muscle mass were positively associated with lower recurrent hospitalizations in patients admitted with acute pancreatitis. These results support the importance of nutritional rehabilitation in patients after admission due to acute pancreatitis.
