ABSORPTION OF CONTRAST-MEDIA DURING ERCP

During this study the absorption rates of two contrast media were meas ured in double-blind design. 33 patients received lopamidol (Solutrast 300(R)), and 30 patients Meglumine lothalamate (Conray 60(R)). A regu lar absorption of the contrast media during ERC, ERP and ERCP could be stated. With reference to the absorption rates a slight, but for stat istically not significant advantage for the contrast medium lopamidol could be ascertained. During ERC the absorption rates ranged from 0.4 to 30%, during ERP from 2.2 to 18.8% and during ERCP from 1.0 and 30.0 %. Consequently the endoscopist always has to take into account an ana phylactoid reaction due to the systemic absorption of contrast media w hich, compared to other examinations with contrast media, happens rela tively seldom.
