[Experience with percutaneous transhepatic cholangiography].

After description of the technical performance of the percutaneous transhepatic cholangiography is reported on experiences with this method. 114 examinations were performed and in 87.6% the bile ducts were described. The result of the percutaneous transhepatic cholangiography confirmed itself in 85% of the patients, in 10% the diagnosis dilated itself according to the result of the operation, and in 5% the diagnosis had to be changed. In 12.4% no biliary duct could be punctured, among them were 10 anicteric patients. The reflux technique described has a high number of impact and a good evidence in the morphological differentiation of the obstruction syndrome. It seems not indicated for anicteric patients. Indications, contraindications and the comparison of the examination method to the ERC are described. The percutaneous transhepatic cholangiography may be used with simple apparative and instrumental means.

[Hepatogenic ascites].

In the paper the intrahepatic (hydrostatic pressure and colloid-osmotic pressure) and extrahepatic (hepatogenic aldosterolism and portosystemic collateralisation) factors effective in the development of an ascites were described and the frequency was tested on own clinical material. The hydrostatic pressure relations are presented as the most essential genetic factor in the development of ascites for hepatogenic reason.

[Information value of 2 color tests in the determination of alanine and aspartate-aminotransferases in liver and biliary tract diseases].

On the basis of examinations of altogether 197 patients the results of the changes of GOT and GPT were compared with the old and new colour tests of the AWD Dresden in normal histology, virus hepatitis, fatty liver, liver cirrhosis and posthepatic occlusion. Though the new colour test reveals a higher sensitivity, the differential diagnosis between selected liver diseases, especially virus hepatitis and posthepatic occlusion syndrome have become more difficult. The cause for this is the less significant separability between the individual regions of reference.

A prototype of a computerized patient record.

Computerized medical record systems (CPRS) should present user and problem oriented views of the patient file. Problem lists, clinical course, medication profiles and results of examinations have to be recorded in a computerized patient record. Patient review screens should give a synopsis of the patient data to inform whenever the patient record is opened. Several different types of data have to be stored in a patient record. Qualitative and quantitative measurements, narratives and images are such examples. Therefore, a CPR must also be able to handle these different data types. New methods and concepts appear frequently in medicine. Thus a CPRS must be flexible enough to cope with coming demands. We developed a prototype of a computer based patient record with a graphical user interface on a SUN workstation. The basis of the system are a dynamic data dictionary, an interpreter language and a large set of basic functions. This approach gives optimal flexibility to the system. A lot of different data types are already supported. Extensions are easily possible. There is also almost no limit concerning the number of medical concepts that can be handled by our prototype. Several applications were built on this platform. Some of them are presented to exemplify the patient and problem oriented handling of the CPR.
