[Anatomo-surgical aspects of peroperative cholangiography in biliary lithiasis]

Biliary anomalies and volumetric changes in the ductal system often make it difficult to identify individual structures during the course of operations for biliary lithiasis. The Authors reviewed 406 peroperative cholangiographies during the course of 1250 operations, evidencing some statistical data regarding the anomalies of greatest interest for surgical practice and stressing the significance and limits of dilation of the V.B.P. On the basis of their personal experience and the relevant literature the Authors conclude that peroperative cholangiography constitutes a useful method not only for diagnostic purposes, but also for correct definition of certain aspects of the extrahepatic biliary ducts.
