[Morphological study of bile in the diagnosis of biliary diseases]

The purpose of this work was to study principles of bile structurization in healthy people and patients with various biliary diseases. 160 patients with different biliary diseases and other diseases of the hepatopancreaticoduodenal zone were examined. Samples of gallbladder bile were taken from corpses of young men, who did not have any diseases of the hepatopancreaticoduodenal zone. Their diagnoses were confirmed by an ultrasound morphological study. Bile was studied by the cuneate dehydration and viscosimetric methods. The structure of facies of gallbladder bile under conditions of absence of diseases of the hepatopancreaticoduodenal zone was shown. The facies have a wide convex peripheral zone (a cushion) without any well-defined border. The central part of the facies is amorphous or fine-grained, sometimes with occasional inclusions of larger crystals. Markers of exacerbation of chronic cholecystitis (dendrites in the central zone of bile facies) as well as signs of the presence of a malignant neoplasm touching the bile (large diamond-shaped crystals in the central zone of bile facies where dendrites begin) were discovered.
