[Significance of residual hepatocholedochal dilatation following principal methods of surgical treatment in benign stenoses of the terminal choledochus].

Out of 305 cases, diagnosed and operated in the clinic over a period of 14 years, the authors have investigated in 164 of them--controlled between 2 and 14 years after surgery--the residual dilatation of the hepatic segment of the choledocus following the application of the major methods of surgical treatment of benign stenoses of the terminal choledocus duct. In view of reducing the disturbances that might occur after surgery of the biliary pathways, the material was investigated and, in the light of the data from the literature, the conditions are discussed, in which the residual hepato-choledocal dilatation should be considered as pathological, the methods of investigation, the difference between the duodeno-biliary reflux and the jejuno-biliary reflux, the anatomo-pathophysiological basis of a more complete and differentiated surgical therapy, the precautions necessary for avoiding remaining intra-hepatic abscesses that might complicate the postoperative evolution.
