[Diagnostic possibilities of mathematical analysis in the evaluation of lithogenicity of the bile].

A simple modification of the triangulation system is suggested for determination of lithogenous potential of bile. Basing on correlation analysis the regression equation is derived for quantitation of total bile acids. This makes time-consuming chromatographic evaluation of bile needless. It is believed sufficient to specify only two parameters (bile acids and cholesterol) as their correlation in a coordinate system allows one to define the zone of cholesterol saturation of bile. A table is presented to simplify calculations.

[Lithogenic properties of bile in cholelithiasis].

To specify lithogenic properties of bile in cholelithiasis as well as the effect of cholecystectomy on biochemical composition of bile, 168 patients with cholelithiasis have been examined. Fifty patients underwent preoperative investigation, some of them were followed up for 1-2 years after cholecystectomy (group 1). The rest postcholecystectomy patients were followed up for 10 years (group 2). Bile levels of cholesterol were evaluated by absolute and relative lipid concentrations. The conclusion is made on the absence of a direct correlation between bile cholesterol supersaturation and cholelithiasis as the above supersaturation occurs in healthy subjects as well. It is noticed that cholecystectomy does not warrant discontinuation of cholesterol supersaturation of bile.
