[Roentgeno-surgical comparisons in choledocholithiasis]

The results of roentgenological investigation of bile ducts are analysed in comparison with the revision findings during cholecystectomy and choledochotomy. Among 61 patients concretions were diagnosed in 37, and in 13 pa tients lethiasis of the ducts was suspected. In 6 observations no concretions were revealed, in 5 patients inadequate contrasting did not allow to judge the state of ducts. Emphasis is laid on the importance of infusion-drip administration of a contrast solution and simultaneous tomography of the ducts for the improved diagnosis of lithiasis.
