[Dynamic scintigraphy of the liver using 131I-rose bengal and the bile acid content of the blood following gastrectomy for cancer].

Liver function was studied in 84 patients with operable stomach cancer prior to and at varying times after gastrectomy using dynamic scintigraphy with 131I-rose bengal and determination by a radioimmunoassay of bile acids in the peripheral blood. A group of patients without signs of focal lesion of the liver and a history of its diseases was examined. It was shown that disorders of hepatocytic function took place before the operation. After gastrectomy the disorders were accompanied by considerable retardation of the basal secretion of bile into the intestine. At the same time an increase in the concentration of bile acids in the peripheral blood above the discriminant level of healthy persons, i.e. over 0.5 mg/l was observed. Disorders of liver function were of long duration and persistent over 1 year after gastrectomy.
