[Modern peroperative radiology in biliary surgery. Results obtained in a continuous series of 341 cases (author's transl)].

The authors study the results obtained in biliary surgery using modern radiological and electronic equipment, combining rapid-sequence image intensified fluorography modular cabinet, television screens and videorecorder. The performance of this apparatus has enabled them to obtain precise measurements of pressure as required, a continuous film reproducing the televised image, films taken in series at the time of and during the desired programming with a very short time required for setting up and with multiple views. Under such conditions, it is possible to avoid troublesome superimpositions, to reduce to the order of 0% the figure for missed calculi and to adequately explore the choledoco-duodenal junction with the possibility of precisely determining the indications for sphincterotomy (Oddi). Finally, the apparatus offers the possibility of combining an abdominal vascular assessment with the biliary investigation, in those cases where such a study may appear useful. Finally, the price of the apparatus is acceptable since it may be used by several departments at the same time within the context of a common operating suite.
