[Possibilities of using of crystal-optic qualities of bile in early diagnostic stage of cholelithiasis].

The aim of our investigation was to study the changes of bile morphology and possibilities of its using in early diagnostic stage of cholelithiasis. We spent the complex investigation of biochemical and crystal-optic qualities of bile in 207 patients with cholelithiasis stage I with different disease duration. The revealed crystal-optic morphotypes have selective morphology due to the bile lithogene level that allows to determine the disease duration and the bile instability to make in-time adequate profilactic.
