[A comparison of intravenous and infusion cholangiography with intraoperative and tomocholangiography (author's transl)].

Seventy-four patients are described who were examined by various cholangiographic methods. 1. In the diagnosis of stenosis of the papilla, intraoperative cholangiography was found to be the most reliable. Intravenous and infusion cholangiography were of equal value and provided less information than the intra-operative examination. 2. For stones, intravenous and infusion cholangiography is significantly better than the intro-operative cholangiogram. Tomography provides no additional information. 3. For stones in the papilla, the intra-operative method is best and is superior to intravenous and infusion cholangiography. Pre-operative tomography resulted in a loss of information.
