[The cholecystogram as a prerequisite of the chemical litholysis from the view of the roentgenologist. (author's transl)].
The preoperative cholecystography and postoperative radiography of gallstones were compared in 68 patients. Calcified structures were detected in 32% of the stones which were free of calcium in the native roentgenograms. The possibility is stressed that the calciumocontent of cholecystographic transparent stones may be responsible for the failure of CDCA-therapy. 52 of the 68 patients additionally received a fat meal. A contraction of the gallbladder was not observed in 25% of these cases. From the missing contraction of the gallbladder should not be concluded that a CDCA-therapy is contraindicated. A functional analysis with a synthetic derivate of cholecystokinin is recommended.
