Abstract
INTRODUCTION Nonalcoholic fatty liver disease (NAFLD) is a pathological manifestation of fatty liver disease in the absence of a clear history of alcohol consumption. It is broadly classified into progressive [...]
: Aim: Nonalcoholic fatty liver disease (NAFLD) can occur due to various reasons after pancreaticoduodenectomy (PD). This study examined the risk and perioperative determinants of NAFLD and fat deposition after PD. Methods: A total of 101 patients who had undergone computed tomography 6 months after PD were included. We compared perioperative factors between patients who developed NAFLD and those who developed fatty deposits after PD. Results: In the NAFLD group, pancreatic cancer was significantly more prevalent among patients who developed postoperative NAFLD (p = 0.024) and had a lower postoperative body mass index (BMI; p = 0.008). Multivariate analysis revealed that pancreatic carcinoma (hazard ratio [HR] 4.42, 95% confidence interval [CI] 1.118–17.442, p = 0.034) and lower postoperative BMI (HR 0.51, 95% CI 0.274–0.954, p = 0.0355) were risk factors for fatty liver. Pancreatic leakage (p = 0.024) and postoperative BMI (p = 0.002) were significantly lower in the fat deposition group than those in the NAFLD group. Multivariate analysis also revealed that a lower postoperative BMI was a risk factor for fat deposition (HR 0.56, 95% CI 0.523–0.982, p = 0.042). Moreover, multivariate analysis revealed that the fat deposition group had significantly lower pancreatic leakage than the NAFLD group (HR 7.944, 95% CI 1.993–63.562, p = 0.049). Conclusion: The findings of this study suggest that postoperative BMI and pancreatic cancer are associated with a higher risk of NAFLD after PD, possibly because of pancreatic exocrine insufficiency and impaired fat absorption.
