There was investigated a hepatic bile in 50 persons, aged 35-58 years old, including 20--practically healthy persons (I group), 20 patients, suffering chronic fibrose-degenerative pancreatitis (CHFDP) without jaundice syndrome (II group) and 10 patients, suffering CHFDP with jaundice syndrome (III group). There were determined the contents of the bile acids, the lipids and electrolytic contents of bile. A trustworthy difference in the bile contents was registered in patients, suffering CHFDP with the jaundice syndrome and without it, comparing with such in healthy persons. This have had permitted to add the complex of medicinal preoperative preparation of these patients substantially, and to apply the electrolytes content of a bile to apply as an additional diagnostic marker.
