['The studying of physical-chemical qualities of liver bile and lipid exchange before and after cholecystectomy.', 'We spent the complex investigation of physical-chemical qualities of bile and lipid levels in 210 patients with cholelithiasis stage I (pre-stone) and in 90 patients with cholelithiasis stage II and III (with gallstones) after cholecystectomy.', 'In all examined patients we revealed disturbances of physical-chemical qualities of bile and lipid exchange. With correlation analysis it was found that bile lithogenity increases in high bile density, in progressing of inflammation process in bile ducts, in increasing of aterogene fractions of blood cholesterol.'] Does [ Wether cholescystectomy affect bile lithogenicity in cholelithiasis ]?
