Jejunoileal bypass (JIB) is a well known cause of steatohepatitis, which may, on occasion, progress to cirrhosis and require liver transplantation. We report 3 patients who underwent orthotopic liver transplantation (OLT) for steatohepatitic cirrhosis secondary to JIB in which the JIB was left intact. All 3 patients have demonstrated recurrent steatosis in the graft after liver transplantation. In two of the cases, the changes are moderately severe, whereas in one case the changes are mild. All 3 patients have essentially normal liver function tests and are clinically asymptomatic; 1 of the patients has undergone removal of the JIB 2.5 years after transplantation. Control hepatic allografts in patients with primary biliary cirrhosis and primary sclerosing cholangitis show negligible fatty change, and in patients who receive transplants for alcoholic steatohepatitis, they rarely (2 of 20 patients) contain greater than 10% fat. We conclude that transplantation alone is not associated with subsequent steatosis. Presence of JIB is, therefore, a continuing risk factor for steatosis in patients who have undergone OLT. Reversal of JIB after OLT may be considered if fatty changes are severe or associated with significant fibrosis.
