[The effect of cholecystectomy on the lipid composition of the liver bile. Follow-up studies in 10 cholecystectomized patients with recurrent calculi in the bile ducts].

In 10 patients who had formed new stones in the common bile duct after cholecystectomy, the lipid composition of the hepatic bile was determined on three different days after relaparotomy and placing of T-tude and the cholesterol content of the stones was investigated. The cholesterol content in 9 out of 10 recurrent gallstones was between 78 and 93%. The lipid content was lithogenic in these 9 cases. In the tenth (a patient with mixed recurring gallstones) solubility for cholesterol was in the critical area. There thus seems to be no normalization of lipid composition in patients with cholesterol stones after cholescystectomy, and the conditions for recurrence of cholesterol stones remain unaltered.
