Cálculos vesiculares: contenido de colesterol y su correlación radiológica / [Gallbladder calculi: cholesterol concentration and its radiologic correlates]

Cholesterol concentration in the gallstones of 84 patients obtained by surgery is studied and radiologic correlation of the stones (lucency and opaqueness) is established with relation to cholesterol concentration. We conclude that 70

of gallstones in our population, contain greater than or equal to 80

of cholesterol and the radiographic appearance of stones in functioning gallbladder is a good method to predict cholesterol content in gallstones.

Composición lipídica biliar de pacientes colecistectomizados en ayunas y en períodos post-ingesta / [Bile lipid composition of cholecystectomized patients during fasting and in postprandial periods]

Fasting state, 1 and 3 hours postprandial biliary lipid periods are studied in 19 cholecystectomized gallstone patients. Methodological items togeher with the characteristics of the kind of diet: normocaloric; lipids, 15

; and carbohydrates, 60

are established. It is concluded that biliary lipids are not quantitatively modified in the subjects on established diet respect fasting, 1 and 3 hours postprandial periods, particularly pointing out that the biliary cholesterol saturation rate remains unchanged--supersaturated--for fasting state, as well as for postprandial periods. We believe that the lack of observable changes may be in relation with the characteristics of the employed diet, which is usually suggested to people suffering from cholecystopathies in Argentina.
