[Percutaneous transhepatic radiomanometry of the bile ducts (PTC-manometry) (author's transl)].

Method and first results of the PTC-manometry are shown in 32 cases. Low residual pressures in bilio-digestive anastomosis and high results both in incomplete bile obstruction and in anicteric patients with incomplete stenosis of the common bile duct and with papillary stenosis suggest a clinical importance. In connection with clinical symptoms and x-ray results it is possible to give informations already preoperatively which we could got only by intraoperative radiomanometry till now. There was no correlation between the maximum size of the common bile duct and the residual pressure.
