Hepatic steatosis, one of the most frequent long-term complications of pancreatectomy, influences not only hepatic function but also survival rate. However, its risk factors and pathogenesis have not been established. The purpose of this study was to clarify the risk factors for hepatic steatosis after pancreatectomy.MethodsIn this retrospective study of 21 patients who had undergone pancreatectomy (19 cases of pancreatoduodenectomy and 2 cases of total pancreatectomy), serum carnitine concentrations, fractions of carnitine, and hepatic attenuation on computed tomography images were analyzed with the aim of identifying risk factors for hepatic steatosis.ResultsThirteen (61.9%) of the 21 patients were diagnosed as having hypocarnitinemia after pancreatectomy. Average hepatic attenuation was as low as 42.2HU (±21.3 SD). A high ratio of acyl/free carnitine was associated with less pronounced hepatic attenuation according to both univariate (P < 0.001) and multivariate (P = 0.020) regression analyses.ConclusionsThe serum carnitine concentrations were low after pancreatectomy in some patients. The statistical analyses suggest that a high ratio of acyl/free carnitine is an independent risk factor for hepatic steatosis after pancreatectomy.
