[Change in the exocrine function of the liver after cholecystectomy under the influence of diet therapy].

In patients with sustained cholecystectomy the content of the basic bile components (cholesterol, cholic acid, total phosphorus) was measured. The cholate-cholesterol coefficient, enabling it to a certain degree to evaluate the lithogeneity of the bile, was calculated. The cholesterol concentration in the serum and bile was contrasted. A total of 104 patients were examined at different post-operative periodss and it was found that in 70 per cent of them the bile was not oversaturated with cholesterol. Two variants of the No. 5 diet were used--the sparing and fatty, differing in the amount of fat and carbohydrates. Under the effect of the No. 5 sparing diet a reduced serum cholesterol concentration was noted along with a noticeable rise of the cholic acid content in the bile with a not too brusque rise of the cholesterol level therein, which led to an increase of the cholate-cholesterol coefficient. Against the background of the treatment with a No. 5 fat diet in evidence was a diminution of the serum cholesterol content, a clearcut fall in the cholesteroland cholic acid concentration in the bile with a continuing fairly high cholate-chole sterol coefficient.
