[Pharmaco-kinetic investigations of a new gall bladder contrast medium--iodoxaminic acid (author's transl)].

Pharmaco-kinetic studies of the cholecystographic contrast medium iodoxaminic acid (Diglumin-Iodaxamate) which is characterised by low toxicity, revealed a half-value period of 93 minutes in the serum and a urinary excretion rate of 12.5% in 24 hours. This indicated the probability that this medium would be suitable for the radiological demonstration of the biliary tract when compared with known and tried contrast media.

[Peritoneoscopy with 2 optical devices: reduced risk - better diagnostic results (author's transl)].

Peritoneoscopy with 2 optical devices was performed in two cases; the technique of this procedure is described. The method allows inspection of areas, which cannot be seen during routine peritoneoscopy, especially of the anterior abdominal wall and of intraabdominal organs covered by adhesions. In addition, this method allows to find out, whether the anterior abdominal wall and vessels in it were injured by the troikart; the risk of the procedure is reduced thereby.
