[Two cases of hepatobiliary scintigraphy of liver transplantation in rejection]

We reported two patients with liver transplantation who are performed hepatobiliary scintigraphy in rejection. In one patient hepatobiliary scintigraphy shows dilatation of bile duct but it shows good clearance from liver. In another patient hepatobiliary scintigraphy shows delayed clearance from liver. Both patients recovered from rejection. There are four main complications--vascular and biliary abnormality, infection, rejection--after liver transplantation. Hepatobiliary scintigraphy shows almost same findings except biliary complication, so it is difficult to distinguish between infection and rejection. But hepatobiliary scintigraphy may be useful to evaluate transplanted liver function in rejection.
